_ Cc: John.Stetkar@nrc.gov I'll plan to do all of the appendices

-at least, the first cut at each. I'm now pretty familiar with what the submittals contain and where some of the warts are. So it's probably easiest for me to tell the rail and highway stories. I need to reserve most of next week for subcommittee homework.

I think that the scope of railway analyses is pretty limi t ed , but everyone analyzes highway accidents. I doubt that I'll finish the highways before subcommittee week , but I'll get a s t art on them. If you have some time , could you work with Derek to fix up the text t hat he wrote (e.g., make it flow better , reduce repetition, etc.)?

[External_Sender] Man-Made Hazards Report Hi Derek, Dennis and I are working to get a draft of the report ready for distribution to the other working group members some time in February. That's the good news. The bad news is that we'll need to pull together a complete list of all references that we've cited in the main part of the report and the append i ces. Since you have already compiled much of that list , we'd like you to finish it. r,Ne're working on an edit to the text in the ma i n report , wh i ch should be done i n the next few days. It might contain a couple additional references , but I'm not sure about that right now. I'll get it to you when we have it reasonably stable.) I originally thought about listing references at the end of each appendix , but that leads to a lot of repetition. So it's best to have Just one References section in the main report that covers everything in the main text and the appendices. In some cases , I dredged up additional references f or th e detailed mater i al In the appendices , including a few RAI re s ponses. I tr i ed to document them as I wrote the material , but I probably d i d not catch all of them. So please read through the appendices for citations that you might not already have on your list. Off the top of my head , I know that I also referred to a mor e recent Revision 3 of the NWMI PSAR than you originally sent us. We're not yet quite sure what we're going to do with the final report , but we should assume that it will be available to the public. So we need to be very careful about not c i ting proprietary information. For the most part , I think that we're OK on that account, since we use docketed submittals, SERs , and references cited in the SRP and Regulatory Guides. I'm not completely sure that the SHINE and NWMI PSAR mater i al is publicly available, but I think that it is -please check i t. I'm much less confident about the Indian Point material that I cited i n Pipellne Appendix D. I got some of that material at least third-hand, so I am not su r e about its original categorization. Please take a very close look at it , considering the history of that issue. Anyway , please compile your first shot at the References section , and then we'll compare notes to see if anything needs tweaking.

Thanks! John 1/1 From: To: /@~} I Widma yer Derek: Stetkar. John

References added. A "reference" from a "Reference" has not been cited* -I think we all agreed this is kosher. Redline/SO.

If you accept all changes, it should be good. I was using Rev. 4 -that was the latest version I had. I hope that was right I I did make one minor substantive change -the letter which described the ACRS plans to respond to the UCS letter was actually an answer from the Chairman -so it needed minor rewording.

We can always cut it out i f the others feel differently. After you insert the references into the stand-alon~

supplement, I'll refo rmat them (if necessary).

I think that it makes sense to keep them in the appendix. John 1/1 4/17/2018 Re: Man-Made Hazards

Man-Made Hazards* Stuff Left To Do Derek, I've copied Mark on this to get his input on the logistics.

So here's my current understanding of what will transpire over the next 6-1/2 weeks: 1 -We finalize the report and the supplement

-to be done this week. Acknowledged.

2 -We discuss the report with the members during an in ternal session at the April full committee meeting (currently s lotted for Saturday morning}. No further changes to the report are planned. The intent is to make sure the members have time to ask questions and to develop a sense of support for an ACRS letter in May. Agreed. 3 -We make t he report available publicly (I think). This is a key i tem , since we're planning to have a public discuss ion during the May fu ll committee meeting , with perhaps an ACRS lette r. We certainly 2/3 4/17/2018 RE: Re: Re: Man-Made Ha zar ds. Stuff Left To Do need to a!ert at least Paul Blanch and UCS to that meeting , so they can plan to attend. (It's already pretty late for that.) I think that it would be a good i dea for them (and the staff) to see the report before the May meeting , so they have time to p r epare comments. I don't know any other way to get the report to them , without making it available publicly in ADAMS. If we're going to do that , we'll need to at least slap a cover on it. Pe r haps we make this decision at the April meeting, but that gives us only 4 weeks until the public discussion in May. We would need to very busy, very early during the week of April 9. In two recent examples, Hossein has finalized detailed technical documents and we have internally called them "White Papers." We have a folder in ADAMS where they are kept as records. I suggest we do this to the two Working Group reports -we can just use the same cover and format he used -we will need to make a Table of Contents -but that is easy. We can put it into ADAMS in that folder as a Committee Working Draft with a header that says "FOR DISCUSSION AT MAY 2018 FULL COMMITIEE MEETING" and make it a public document.

We can do th is as soon as needed to make it available to the public, I suggest this be the path desired by the Working Group to be discussed at April FC. In the meantime, we can get them ready with the Covers and TOCs. I suppose we should contact the two interested parties ASAP with a heads up and then notify them as soon as the draft report is up in ADAMS. If you think it is the right thing to do -I suppose we should get at least Dennis and the Leadersh ip to agree -I can contact them (Blanch and UCS) to provide an early notification that the subject will be in May. Then a formal letter that goes out under Mike would probably be desirable (as part of the record of the FINAL responses to the incomings).

4 -Discussion dur i ng May full cormmittee meeting, with poss i ble ACRS letter or working group letter. I think i t is appropriate for the Committee , if it so chooses , to send a letter to the Commission, and attach the Final Report -I would leave the Supplemental Report in ADAMS, not attach it. think it is okay to refer to it as "The Working Group Report" when it would be tiresome to keep providing the full Title. I am not aware of anything going to the Commission or EDO from a "working group of the ACRS." I wonder if we shou l d allow the two stakeholders mentioned above added time at the May Fu ll Committee meeting, more than 5 minutes? OR would it be better to tell them the ACRS report is final, they have 5 minutes at the meeting , and they should send any commen ts to the Commission?

Perhaps discuss this in April. Did I mi ss anything?

I don't think so. As for your PS -I think these logistics will work. If there was a desire to go to a NUREG report, that would substa n tia ll y delay things , to include a technical editor and other "QA" steps required.

What are your thoughts on how we get things done? In particu l ar , what are your thoughts about making the report available in ADAMS before the May meeting? John P.S., If the logis tics seem impossible , we need to settle on a clear Plan B ASAP. T he paperwork is in pr og ress t o t erminate me, effective May 5.

[External_Sender] Man-Made Hazards -Stuff Left To Do My recollection about our outreach to UCS for the December 2015 societa l risk subcommittee meeting is a bit fuzzy. I'm pretty sure that we did that through an email from John Lai to Dave L ochbaum o r Ed Lyman. (I think that we a l so contacted severa l others the same way.) We certainly did not send a formal l etter Invitation.

However, this situation Is different , considering the ACRS correspondence with Paul Blanch and the NRC Chairman correspondence with Dave Lochbaum.

I agree -a lette r from ACRS , Mike is probably appropriate.

I think that Derek shou ld contact each of them very soon by email, a l erting them to the May 3 meeting and its topic -the working group report on eva l uation and review of man-made externa l hazards. Mike shou l d follow up with confirma t ory letters, so we and they have a record of the correspondence.

We shou ld a l so alert them that our work i ng group report will be ava ilable in ADAMS, and l et them know when i t is. I will draft up an email with the Informat io n that is kn ow n at this t i me, with the Ideas expressed in the next parag r aph, and clrculate.

Need to have feedback from Mark and Andrea (If she Is going to be around). Gov't offices closed today. I think that we shou ld afford them more than a nominal 5 minutes presentation time. If we have 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> slotted for the topic , then about 15 minutes each seems reasonab l e. or perhaps 20-25 minutes total if they want to consolidate their commen t s. We sho uld also st re ss that more comprehensive written comments are always appreciated and will be made part of the meeting record. H owever, I don't want to get mired in de t a il s of the Indian Point analysis and review. That i s not the purpose of o ur work i ng group report or the ACRS briefing. Of course, that being said, we can't dictate what the y present, except to ind ica te that we will focus on a range of man-made ha zards, technical basis for eva l ua t ion and r eview guidance, and consistency of applications of the guidance. Tha t might forestall too much discussion about that one particular analysis.

We should also alert the staff (not sure who , considering the history), but indicate that we do not expect any presentations from them. At this point, maybe the contact person for the Natural Hazards COE , who can inform others? Your thoughts?

[External_SenderJ Man-Made Hazards -Stuff Left To Do Derek, I've copied Mark on this to get his input on the logistics. So here's my current understanding of what will transpire over the next 6-1/2 weeks: 1 -We finalize the report and the supplement

-to be done this week. A cknowledge

d. 2 -We discuss the report with the members during an internal session at the April full committee meeting (currently slotted for Saturday morning).

No further changes to the report are planned. The intent is to make sure the members have time to ask questions and to develop a sense of support for an ACRS letter in May. Agreed. 3 -We make the report available publicly (I think). This is a key i tem, since we're planning to have a public discussion during the May full committee meeting, with perhaps an ACRS letter. We certainly need to alert at least Paul Blanch and UCS to that meeting, so they can plan to attend. (It's already pretty late for that.) I think that it would be a good idea for them (and the staff) to see the report before the May meeting, so they have time to prepare comments.

I don't know any other way to get the report to them, w~hout making it available publicly in ADAMS. If we're going to do that, we'll need to at least slap a cover on it. Perhaps we make this decision at the April meeting, but that gives us only 4 weeks until the public discussion in May. We would need to very busy, very early during the week of Apr i l 9.

We can do this as soon as needed to make it available to the public, I suggest this be the path desired by the Working Group to be discussed at April FC. In the meantime, we can get them ready with the Covers and TOCs. I suppose we should contact the two interested parties ASAP with a heads up and then notify them as soon as the draft report is up in ADAMS. If you think it is the right thing to do -I suppose we should get at least Dennis and the Leadership to agree -I can contact them (Blanch and UCS) to provide an early notification that the subject will be in May. Then a formal letter that goes out under Mike would probably be desirable (as part of the record of the F INAL responses to t he incomings).

Man-Made Hazard s -Stuff Left To Do 1/5 4/17/2018 Re: Man-Made Hazards -Stuff Left To Do My recoUectlon about our outreach to UCS for the December 2015 societa l risk subcommittee meeting Is a bi t fuzzy. I'm pretty sure that we did that through an emai l from John Lai to Dave Lochbaum or Ed Lyman. (I think that we al so contacted several others t he same way.) We certainly did not send a formal letter invitation.

However, this situation is differe nt, considering the ACRS correspondence wit h Paul Blanch and the NRC Chairman correspon d ence with Dave Lo chbaum. I agree -a l etter from ACRS , Mike is probably appropriate.

OK -sounds fine I th i nk that Derek should contact each of them very soon by email , alerting them to the May 3 meeting and Its t opic -th e working group report on evaluat io n and review of man-made external hazards. Mike shou ld follow up with confirmatory l etters , so we and they have a reco r d of the correspondence. We should also a l ert them that our working group repo rt w ill be available In ADAMS, and let them know when I t Is. I will draft up an emai l with th e information that i s known at this t ime. with the ideas expressed in the next paragraph, and circulate.

Ne ed to have feedback from Mark a n d Andrea (if she i s going t o be around). Gov't offices c lo sed toda y. OK -sounds fine I t hi nk that we should afford them more than a nominal 5 minutes pre sen tation time. If we have 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> s lott ed for t he t opic , the n about 15 m inu tes each seems reasonable , or perhaps 20-25 minutes total if they want to consolidate their comme nt s. We shou ld a l so stress that more comprehensive writte n comments are always appreciated and wi ll be made part of th e meet in g record. However , I don't want t o get mired in details of the Indian Point analysis and review. That Is not the purpose of our work i ng group report or the ACRS briefing. Of course , that belng said , we can't dictate what they present, except t o i ndicate that we will focus on a range of man-made hazards , technical basis f or eva l uation and rev i e w guidance, and consistency of app l ications of the guidance. T ha t might forestall too much d iscussion about that one particu lar analysis.

OK -I would suggest 20-25 min combined We should also alert the staff (not sure who , considering the history), b ut indicate that we do not expect any prese nta tio n s fr om them.

[External_Sender] Man-Made Hazards -Stuff Left To Do Derek , I've copied Mark on thi s to get h is input on the logist i cs. So here's my current understanding of what will tra nspire over the next 6-1/2 weeks: 1

• We finalize the report and the supplemen t -to be done thi s week. Acknowledged.

2 -We discuss the report with the members during an interna l session at the April full committee meeting (currently s lott ed for Saturday morning).

No further changes to the report are planned. Th e inte nt is to make sure the members ha ve time to ask questions and to develop a sense of support for an ACRS l etter in May. Ag reed. 3 -We make the report available publicly (I think). This is a key item, since we're planning to have a public discussion during the May full committee meeting. with perhaps an ACRS letter. We certainly need to alert at least Paul Blanch and UCS to that meeting, so they can plan to attend. (It's already pretty late for that.) I think tha t It would be a good i dea for t hem (and t h e staff) to see the report before the May meeting, so th ey have t i me to prepare comments.

I don't know any other way to get the report to them. without maklng It available publicly In ADAMS. I f we're going to do that, we'll need to at l east s lap a cover on i t. Perhaps we make this decision at the April meeting, but tha t gives us only 4 weeks until t he public discussion In May. We would need to very busy , very early during the week of April 9. In two recent examples, Hossai n has finalized detailed technica l documents and we have interna ll y called them 'White Papers." We have a folder in ADAMS where they are kept as records. I suggest we do t h is to the two Working Group reports -we can just use the same cover and format he used -we will need to make a Tab l e of Contents -b ut that i s easy. We can put it into ADAMS in t h at fo ld er as a Committee Working Draft with a header that says "FOR D I SCUSS I O N AT MAY 2018 FULL COMM I TIEE MEE T IN G" and make it a public document.

We can do this as soon as needed to make it available t o the public , I 4/5 4/17/2018 Re: Man-Made Hazards -Stuff left To Do s u ggest th i s b e the path desired by the Working G r o u p to be disc u ssed a!

T h en a fo r mal letter t hat goes out under M i ke wou l d probab l y be desirable (as part of the r ecord of the F I NAL responses to the incomings). 4 -Discussion during May full c ommitte e meeting, with pos s ibl e ACR S letter or working group letter. I think It Is appropriate for t he Committee, if I t so chooses , to send a l etter to the Commiss i on, and attach the Fina l Repo rt -I wou l d leave the Supplemental Report in ADAMS, not at t ac h it.

I'm pretty sure that we did that through an email from John Lai to Dave Lochbaum or Ed Lyman. (I think that we also contacted several others the same way.) We certainly did not send a formal letter invitation. However , this situat i on is different , considering the ACRS correspondence with Paul Blanch and the NRC Chairman cor r espondence with Dave Lochbaum. I ag r ee -a l etter f r om ACRS , Mike is probab l y appropr i ate. OK -so unds fine I think that Derek should contact each of them very soon by email , alerting them to the May 3 meeting and its topic -the wor1<ing group report on evaluation and review of man-made external hazards. Mike should follow up with confirmatory letters, so we and t hey have a record of the correspondence. We should also alert them that our wor1<ing group report will be a v ailable in ADAMS , and let them know when it is. I will draft up an email with th~ informat i on that is known at this time , with the ideas expressed i n the next paragraph , and circulate. Need to have feedback from Mark and Andrea (if she is going to be around). Gov't offices closed today. OK -sounds fine I thin k that we should afford them more than a nominal 5 minute s presentation time. If we have 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> slotted for the top i c. then about 1 5 minutes each seems reasonable, or perhaps 20-25 minutes tota l if they want to consolidate their comments. We should also s tress that mor e comprehen s ive written comment s are alway s appre c iated and will be made part of the meeting record. However , I do n't want to get mired in details of the Indian Point ana l ysis and review. That is not t he purpose of our working group report or the ACRS briefing.

Of course , that being sa i d, we can't di c tate what they present , except to i ndicate tha t we will focus on a range of man-made hazards , technical basis for evaluation and review guidance , and consistency of applications of the guidance.

That might forestall too much discussion about that one particular ana lysis.

I don't know any other way to get the report to them, without making it available publicly in ADAMS. If we're going to do that , we'll need to at least slap a cover on it. Perhaps we make this decision at the April meeting , but that g i ves us only 4 weeks until the public discussion in May. We would need to very busy , very early during the week of April 9. In two recent examp l es, Hossein has fina l ized detailed technical documents and we have internally called them "White Papers." We have a folder in ADAMS where they are kept as records. I suggest we do this to the two Working Group reports -we can just use the same cover and format he used -we will need to make a Table of Contents -but that is easy. We can put it into ADAMS in that folder as a Committee Working Draft with a header that says "FOR DISCUSSION AT MAY 2018 FULL COMMITTEE MEETING" and make it a public document.

We can do this as soon as needed to make it available to the public, I suggest this be the path desired by the Work ing 7/9 4/17/2018 R e: Man-Made Ha zards -S tuff Left To Do Group to be discussed at April FC.

We certainly did not send a 3/12 4/17/201S Re: Man-Made Hazards -Stuff Left To Do formal letter invitation. However , th is s it uation is d ifferen t , considering the ACRS correspondence with Paul Blanch and the NRC Cha i rman correspondence with Dave Lochbaum.

I agree -a lette r from ACRS , Mike is probably appropriate.

OK -sounds fine I think that De re k should contact each of them very soon by email, alerting them to the May 3 meeting and its topic -the working group report on evaluation and review of man-made external hazards. Mike should follow up with confirmatory letters , so we and they have a record of the correspondence.

We shou ld also alert them that our work i ng group report will be available in ADAMS , and let them know when it is. I will d r aft up an email with the i nformation that is known at this time, with th e id eas expressed in the next paragraph , and circulate.

Need to have feedback from Mark and A n drea (i f she is going to be around). Gov't offices closed today. OK -sounds fine I think that we should afford them more than a nom i nal 5 m i nutes presentation time. If we have 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> s l otted for the topic, then about 15 minutes each seems reasonable , or perhaps 20-25 m i nutes total if they want to consolidate thei r comments.

We shou ld a l so stress that more comprehensive written comments are always appreciated and will be made part of the meeting record. However , I don't want to get mired in details of the Indian Po i nt analysis and review. That is not the purpose of our working group report or the ACRS briefing. Of course, that be i ng said , we can't dictate what they present , except to i ndicate that we will focus on a range of man-made hazards, technica l bas i s for evaluation and rev i ew guidance , and consistency of applications of the guidance. That m i ght forestall too much dis c uss ion about that one particular analys i s. OK -I would suggest 20-25 min combi ned We should also alert t he staff (not sure who , considening the history), but indicate that we do not expect any prese ntations from them. At this point , maybe the contact person for the Na t ural Hazards COE , who can info rm others? OK -sou nd s fine Your thoughts?

Re: Man-M ade Hazard s -Stuff Left To Do Hi M ike, As Dennis noted, we should contact Paul Blanch and Dave Lochbaum ASAP to alert them to the May meeting. I think that we should elicit comments from the members during the April retreat. Unless there are egregious errors, we don't plan any major changes to the report. My primary objective for the April discussion is to answer questions about technical details (if any) and gain a sense of member support for the recommendations.

Man-Made Hazards -Stuff left To Do Derek , I've copied Mark on t his to get his input on the logistics.

So here's my current understanding of what will transpire over the next 6-1/2 weeks: 1 -We finalize the report and the supplement

-to be done this week. Acknowle dged. 2 -We discuss the report with the members during an interna l session at the April full committee meet i ng {currently slotted for Saturday morning).

No further changes to the report are planned. The Intent is to ma ke sure the members have time to ask questions and to develop a sense of support for an ACRS letter in May. Agreed. 3 -We make the report available publicly {I think). Th i s is a key item, since we're planning to have a public discussion during the May full committee meeting , with perhaps an ACRS letter. We certa i nly need to alert at least Paul Blanch and UCS to that meeting , so they can plan to attend. {I t's already pretty late for that.) I think t ha t it would be a good idea for them {and the staff) to see the report before the May meeting , so they have time 9/12 4/1 7/201 8 R e: M a n-M ad e H aza rd s -Stuff Left To D o t o prepare c omme n ts. I d o n't know any other way to get the report to t h em , w i thout maki n g it available public l y i n ADAMS. I f we're going t o d o that , we'll need to at least slap a cove r on i t. Perhaps we make this d ecis io n at the April mee ti ng , but that gives us only 4 weeks until t he public discuss i on i n May. We would need to ve ry busy , very early during the wee k of April 9. In two recent examp l es, Hossein has final i zed deta il ed technical documents and we have internally ca ll ed them "White Papers." We have a f ol d er in ADAMS where they are kept as records. I suggest we do this to the two Working Group reports -we can just use the same cover and format he used -we will need to make a Tab l e of Contents -but that is easy. We can put it into ADAMS in that folder as a Committee Working Draft with a header that says " FOR DISCUSS I ON AT MAY 2018 FULL COMMITIE E MEET I NG" and make it a public document.

We can do this as soon as needed to make it avai l able to t he public , I suggest this be the path desired by the Working Group to be discussed at April F C. In t h e meantime , we can get them ready with the Covers and TOCs. I s u ppose we should contact the two interested parties ASAP with a heads up and then notify them as soon as the draft report is up in ADAMS. If you think it is t h e right thing to do -I suppose 10/1 2 4/17/2018 Re: Man-Made Hazards

• S tuff Left To Do we should get at least Dennis and the Leadership to agree -I can contact them (Blanch and UCS) to provide an early notification that the subject will be in May. Then a formal lette r that goes out under Mike would probably be desirable (as part of the reco rd of the FINAL responses to the i ncomings).

4 -Discussion during May full committee meeting , with possible ACRS letter or working group letter. I think it is appropriate for the Committee, if it so chooses, to send a letter to the

• Commission , and attach the Final Report -I would leave the Supplemental Report in ADAMS , not attach it. I think it is okay to refer to it as "T he Working Group Report" when it wou l d be tiresome to keep providing the fu ll Tit l e. I am not aware of anything going to the Commission or EDO from a "working group of the ACRS." I wonder if we should allow the two stakeho l ders mentioned above added time at the May Full Committee meeting , more than 5 minutes? OR would it be better to te ll them the ACRS report is final , they have 5 minutes at the meeting , and they should send any comments to the Commission?

Perhaps discuss this in Apr il. 11/12 4/17/2018 CbX5) Re: Man-Made Hazards* Stuff Left To Do Diel I miss anything?

I don't think so. As for your PS -I think these logistics wi ll work. I f there was a desire to go to a NUREG report , that wou ld substa nt ia ll y de l ay things , to i nclude a t echnical editor and other <<QA" steps required.

What are your thoughts on how we get things done? In particular , what are your thoughts about making the report available in ADAMS before the May meeting? John P.S., If the logistics seem impossible , we need to settle on a clear Plan B ASAP. The paperwork i s i n progress to term i nate me , effect i ve May 5. If the ACRS meeting on this topic is pushed to June or July , either Dennis will need to take the lead , or perhaps I could present the report as an " invited expert". 1 2/12 4/17/2018 R e: Man-Made Hazards -Stuff Left To Do

I am not aware of anything going to the Commission or EDO from a "working group of the ACRS." 13/15 4117 1 2018 Re: Man-Made Hazards

• Stuff Left To Do I wonder i f we should allow the two stakeholders mentioned above added time at the May Full Committee meeting , more than 5 minutes? OR would it be better to tell them the ACRS report is final , they have 5 minutes at the meeting, and they should se nd any comments to the Commission?

Perhaps di scuss this in April. Did I m iss anything?

I don't think so. As for your PS -I th ink these logistic s will work. If there was a desire to go to a NUREG report , that would substantia ll y de lay things, to includ e a technical ed i tor and other "QA" steps required.

What are your thoughts on how we get things done? In particular, what are your thoughts about mak in g the report available in ADAMS before the May meeting? John 14115 4/17/2018 Cb X 6) Re: Man-Made Hazards -stuff Left To Do P.S., If the logistics seem impossible , we need to settle on a clear Plan B ASAP. The paperwork is in progress to terminate me, effective May 5. If the ACRS meeting on this topic is pushed to June or July , either Dennis will need to take the lead , or perhaps I could present the report as an " invited expert". 1 5/15 4/17/2018 Re: Draft Supplemental Report with References Incl u ded.

Re: Draft email for Mr Blanch and Mr Lochbaum Looks good. I have only three comme*nts. (1) I think that it makes sense to i nclude the supplemental information as Appendix G of the working group report. That provides background and context for tlhe report , and it is useful information for many readers. We can discuss that i n April. For these emails , it's less confusing i f we c ite only one working group r eport. If we later dec i de to keep t he supplemental information separate, we can always tell fo l ks where to find that report. (2) We should encourage Mr. Blanch and Mr. Lochbaum to prov i de written comments to the Committee and note that those comments will be i ncluded in the meeting record. That reduces the time pressure for a 1 0-minute oral presentation.

(3) As for timing of filing the report in ADAMS , we should probably wait until after the April ret r eat session, i n case some of that discussion prompts last-minute tweaks. Rather than say the report will be available

" shortly", it might be better to say "in early April". We shou l d shoot for early in the week of April 9.

.__ ____ _, Dere k, Mike, and Dennis, That's unfortunate , considering his long involvement with t he pipeline issue. I don't think that we have any flexibility on the date, unless Mike and Dennis decide otherwise.

We're trying to get this wrapped up before I leave the Committee, which will be effective May 5. If we postpone the Full Committee briefing, Dennis would need to take the lead, or I would need to be called in as an "inv i ted expert" or something similar. That's certainly feasible, if we collectively t hink that it is important for Mr. Blanch to attend the meeting. I'm sensitive to the relatively short notice for the meeting. W ri tten comments are often better than short oral presentations, so we would not necessarily lose the benefit of his technical input. However , speaking on the record at the meet i ng is important to some people. I'm on the fence regarding postponement until a date when Mr. Blanch can attend, leaning slightly in favor of postponement.

Mike and Dennis -What do you think? John In a message dated 3/26/2018 1:24:04 PM Central Standard Time, Derek.Widmayer@nrc.gov writes: Gentlemen:

Re: Invitation to r eview ACRS Report and present commen t s at upcoming meeting. Derek: I am going to attem pt to rearrange my sche dule but not overly optimistic I can do so.

I just talked to Dave Lochbaum who is also invited to speak before the ACRS. Dave has agreed to present my position on the gas lines as related to Indian Point and Turkey Point. His views are similar to mine. Our presentations will be somewhat independent of the other. My preference for the full ACRS meeting would be the June dates but I am also available in July.

His views are simi lar to mine. Our pre sentations will be somewhat independent of the other. My preference for the full ACRS meeting would be the June dates but I am also a va ilable in July.

We're trying to get this wrapped up before I leave the Committee, which will be effective May 5. If we postpone the Full Committee briefing , Dennis would need to take the lead, or I would need to be called in as an "invited expert" or something similar. That's certainly feasible , if we collectively think that it is im portant for Mr. Blanch to attend the meeting. I'm sensitive to the relatively short notice for the meeting. Written co mments are often better than short oral presentations, so we would not necessarily lose the benefit of his technical i nput.

Man-Made Hazards The following is a comprehensive list of man-made "hazards ," comprised from internet searches, newspaper and magazine articles, and other various sources. Many sources are "lists" of the "worst" disastrous events or instances of a " hazard," compiled by the authors of the lists using various "metrics>> for the measure of why the event is considered one of the " worst." Most of these "metrics," are some variant of the impacts of the event on loss of human life and/or casualties, costs of property damage (or loss of revenue}, environmental loss (some measure of land/water/air rendered " harmful" to humans) or ecological loss (some measure of land/water/air rendered "harmful" to plants and animals), or a combinat 1 i on of more than one of these. There are several ways these events are " grouped" to compile these lists, so the organization of the following list could be done in several ways. Further evaluation of some kind could probably be performed to result in a l i st of man-made " hazards" that " likely" could impact a nuclear facility, or which should be considered in evaluating a nuclear facility for impacts from such hazards. One " evaluation" of the list has already been completed: any man-made hazard that was evaluated in the NRC safety evaluation documents compiled for this effort i s included in this l i st.

Working Gr oup Report on Man-Made Hazards Colleagues, Attached is a copy of our work i ng group report on man-made external hazards that I mentioned briefly during P&P Friday. We plan to discuss the report in an internal ACRS retreat session during the April Full Comm i ttee meeting. The purpose of lhat session is to familiarize everyone with the report and our conclusions and recommendations, and to discuss a path forward for possible action by the Committee.

During our working group meet i ng on F riday , we tentatively decided to formally present the report at the May Full Committee meeting, inviting the NRC staff and interested members of the public to attend. Our hope is for an ACRS letter transmitting the report to the Comm i ss i on and endorsing some or all of the working group recommendations.

The system was invented with all good intentions, but I don't think it functions the way that most people "think." Anyway. The Program Plan is within an ML " package." This allows one to create several documents and work on them separately , and then pile them together when one is ready to distribute. This mechanism is not supposed to make the i ndividual documents "invisible" but anyway. ML16229A350 is the "package." See i f you can bring that up. The Plan is one of the documents in that package.

At the conclusion of the discussion, I believe the Working Group will get "permission" from the full membership to make the report available for you and others to review. I would expect, therefore, it will become publicly available short ly thereafter, maybe on Tuesday, ifit goes to the ADAMS processors on Monday. l will ask pennission tomorrow to email the report to you (and David Lochbaum) at the conclusion of the discussion if the full committee says the report can go public, then you will have it early to begin your review. Look for something from me tomorrow one way or another. Derek -----Or iginal Message-----

• Because the report will remain a Draft ACRS Working Product during this time , ACRS staff will plan on the meeting being closed and will check with OGC to ensure this Is allowed.

• After NRC staff review and the Subcommittee meeting , the Working Group will make the report publicly available (incorporating revisions agreed to after the staff review , if needed).

• The Full Committee will hear from the staff (if they desire) and the members of the public who have an interest in this work and who will be invited to present (Paul Blanch and David Lochbaum) after the Subcommittee meet i ng at a future Full Committee meeting and after the report is made publicly available.

Th e Full Committee will decide at th i s future Full Committee m e eting whether to send a letter attaching the report with c onclusions and recommendations to the Commission or the EDO. D e rek A. Widmay e r A C RS/Technical Support Branch ._I Cb .... X 6 __ ) __ _,I (c ell) dcrek.wjdmn

• The Full Committee session scheduled for May 3,c:' will be cancelled.

• ACRS Staff (Derek Widmayer) will notify Paul Blanch and David Lochbaum of this immediately by email (ac , '). ACRS Staff (Widmayer) will also send an email to the EHCOE regarding the meeting cancellation (done). NRO and NRR Management will be notified by Mike Snodderly and Weidong Wang at the Monday AM Management Meetings for NRO and NRR. Other notifications will be sent as needed. ACRS Executive Director (Andrea Veil) will notify the EDO's Assistant for Operations (AO) at her next periodic meeting (Tuesday, April 1 oth) of this agreed process.

• The Working Group will prepare the Report for review and transmit it to the NRC staff (exactly who to formally send it to is yet to be decided).

This will be done as soon as possible EARLY NEXT WEEK AFTER ACRS MEMBER FEEDBACK.

At a minimum, the Working Group would like the report to be reviewed by the External Hazards Center of Expertise (EHCOE). This invitation will indicate that the ACRS will hold a Subcommittee meet i ng on the report if the staff desires , at which they can present their review of the report.

• ACRS Staff (Widmayer) will establish a time for this Subcommitte~

meeting on the ACRS SC schedule at which the staff will be invited to provide a presentation of their review of the report (if they desire).

" Wankegan" Is a direct quote from the reference c i tation in SRP 3.1.5.6. That's why I stuck the [sic] in the c i tation.

Man-Made Hazards Report and MOU Andrea: Reporting on the subject subjects

• Repo , rt-Joe Sebrosky from NRR called me this morning along wi t h his BC-they wanted a big picture on where the Man-Made Hazards report came from and what was happening next. I gave them the details on the background and summarized the next steps as agreed to at the April Full Committee meeting. During these discussions, it seemed that sending the report to the EDO and asking for review (as suggested by Mike Snodderly) is the way to go. They indicated that it was probably not clear to anyone in NRR who might all should be involved in the review, so It would be best for the NRO Director lo decide. They also pointed out that RES might be interested in commenting. I also told them I had not scheduled a SC meeting yet , but consider i ng all of the staff interest, I suggested it might be in 2 or 3 months in order for all parties to do a thorough review and prepare for the meeting. So I will find a time and put it In webACTS as tentative for now. MOU -As you know, I asked OCIO about the CUI issue -they have made a suggested revision and also asked if I wanted them to look at th e SUNSI section and see i f their suggestion makes sense -so I told them I would ask you if that was OK. I wi ll make sure them comment on l y on that section and only in response to the question posed by Larry in the EDO's Office. DAW Dch..c.A t:A-.

That seems rather short for public reading and preparation of comments , especially since the July 4 holiday is in that period (folks might have already planned a whole week away, since the 4th Is in the middle of the week). Also, based on my experience from trying to get the report :'done" this week, if there are any changes at all as a result of the subcommittee meeting, we need to plan at least a week's delay before the report is publicly available.

So, no, I don't think that a mid-June subcommittee meeting and a July Full Committee briefing would work.

Man-Made Hazards Meetings Colleagues, This morning, Mark sent out the meeting schedules for the next few months. The man-made hazards line item has correctly disappeared from the May Full Committee meeting list. Members make travel plans based on the published schedule, especially for the next 60-90 days. We seem to have two options for the path forward on the man-made hazards topic. (1) Closed subcommittee meeting on June 4, Full Committee briefing i n July 1/2 4/17/2018 Re: Man-Made Hazards Meetings (2) Closed subcommittee meeting on June 21 , Full Committee briefing in September There are , of course, other possible comb i nations , but this suffices for now. I thought that Mark or Derek was going to pulse members about their availability for June 4. That hasn't happened.

Since it's now mid-Thursday, I think that we should do that ASAP. Should I take the initiative and list the options shown above? I'm really sorry to bother you with this , but I'm gett i ng rather frustrated by this whole process. John 2/2 4/17/20 18

{NUREGs , reports , obscure citations , e t c.). So far , we've had varying success in trying to find some of the references that pre-date the mld-70's. That's probably been you r experience , too. Aft e r we've finished our initial searches , we'll need to compare notes on what the three of us have , and what we're missing. Dennis and I plan to do that during the Sep t ember subcommittee week. A coup l e of weeks ago , you said t h at you had compiled many of the submitta l s for man-made hazards (e.g., Chapter 2 of COL applications , SHINE , NWM I , and whatever else we had on our 11st). You mentioned that you had sent that stuff to us , bu t neither Dennis nor I can find i t i n ou r flies. Do you have that mater i al? If so , can yo u get it to us? Thanks , John 1/1 4/17/2018

I am working on the " External Man-Made Hazards" report (currently w i th John and Dennis), and they have asked me to locate and make avallable to them about a dozen references from the Standard Review Plan and a couple of Reg Guides. These references are, for the most part , very old, and such have never been added to ADAMS In electronic form. Most of them are , however , showing up in the ADAMS "Legacy Library* or in anciml1 Docket Files (for example, an affidavit from an NRC employee on the Skagit Nuclear Power Plant license!)

The Technical Library is running them down for me, and is nearly finished. Of the dozen, It turns out three of them have been located in electronic format, so I have downloaded those. What will probably be needed for the other Nine is a hard copy will need to be made, and that is where I will need your help. Have you ever used a NUDOCS station? These old references will be found in microfiche form. When the Tech Library is done, they will provide the microfiche addresses for them all, and then somebody has to sit at a NUDOCS station and make the hard copy. it Is very tedious, but I found it very fun (in the old daysl). I think there wlll be a couple of microfiche that will be found in the NUDOCS station in the Technical Library , and then the rest will be in the NUDOCS station in the public document room. I will le t you know when the Library is done with the research. Let me know if this sounds like (also you Mark) some th ing somebody else m ight like to (or shoul d) do.

I was ab l e to find of the Elusive References on available technical document resources that are available to the NRC Technica l Library , and l ibrary staff was able to find one other. 1/3 4/17/2018 Re: Man-Made Hazards In the meantime , the remaining ruM documents are being chased by the Technical Library and the Public Document Room , and I hope to hear from them soon. It has been my experience with the NRC document system that EVERY document that I have looked for has been availab l e on microfiche. Sometimes it is just a matter of knowing where and how to look , so I am hoping that the PDR folks retain those skills! (I had an amazingly fun project when I was in NMSS he lp ing solve a legal case for a Decommissioning project -where a major contamination had taken place in the 60s and a " partial" cleanup had been done. The current owner was doing a " final" decommissioning and was trying not to pay for any of the added cleanup that was needed to bring the " partially" c l eaned up areas up to current standards. Fascinating stuff-I had to run down licens i ng documents clear back to the 50s.) So hopefully everything should still be there someplace. Derek From:!(b)(6) ! ._!(b_X6_) ______ __.

Dennis suggested that we ask the NRC library to try to find them. Before we do that , did you find any of them during your searches?

S ub ject: RI:: Rl:H:Rl:NCES need for ACRS Hello Derek, We re ceived your 11 st of referen ces. I have mad e a first pass through them and, as you noted, many seem to be related to docket mes. The Public Document Room at NRC headquarters does have a docke t microfiche collection and I'm going to enlist the help of my colleagues, Sardar and Lee (copied on this email-they also work In the Technical Library) to search through the docket microfiche on Monday to see if they can loca te any of these references there. The only reference I've located 1n electronic format so far is #10 and I found it on the EPRI Web site for download at https:/lwww.eprLcom/#/pages/producUNP-5283-sRA %20%20%20%20%20%20%20/

If we do locate the other references only on m ic rofiche or print here at he adquarters, you m ig ht want to consider asking an ACRS colleague to come to the Te chnical Library or Public Document Room to view the items on your behalf as we cannot make electronic copies of microfiche or print documents for you. Also , please note that for any NRG documents we locate for which we may have on microfiche, if you need an " offic i al agency record" copy of the document or if you would like the document to be made electronically ava i lab l e in ADAMS , you would need to go th ro ug h r:eGO!.d.s..resource

@nc.c ,.g, ov for that service. We can assist with verify i ng the references you have and obtain i ng microfiche add re sses , but then you would need to work with the Records team to get the m digitized/put i nto ADAMS. H owever , you can have an ACRS colleague view the documents and save electron i c " reference" copies if that's all you need. Lee and/or Sardar w i ll be in touch next week wi t h further search results.

REF E RENC ES ne e d for ACRS H ello I am working on a project for the ACRS and I have a list of about a dozen r eferences that I cou ld use some help r unning down. I have attached the list whi c h contains as complete a reference as possible. (one is crossed out because I did find thi s one on my own). These references all are cited In the Standard Review Pl ans and Reg G u ides used by NRO and NRR for reactor reviews , however , they were first cited In the early 70s and 80s and have not been replaced or removed from any revisions of the documents.

Since they are old , they don't appear i n ADAMS as referenced. I th i n k some of them might be in the legacy library o f ADAMs but I have not successfully found them (and even if I did, I work permanent te lework and am not nea r any NUD0Cs mach i nes anymore). Also , as noted and w i th emphas i s added , most of them mighVshould be included i n Dockets. It Is a l so poss i b l e (I guess) tha t some of them m ig ht be available at the Law Library?

Please advise on how I should continue?

If you can help run these down , do you need a CAC number or are you covered for any work you do? (Time recording is changing i n one week , so I thought I would ask in case there Is a change to how you are to do business).

Re: Update on Elus iv e References

Man-Made Hazards Hi Derek, I think that we shou l d declare a truce for the "Elusive References" (not a victory , but a draw). I'm p retty confident that missing References 2 , 3 , and 4 are backups fo r Reference

1. I know that 3 and 4 are consultant reports , which were likely never filed on the docket. Reference 2 i s cited in the guidance , but it is always pa i red w ith Reference

1. So I think that Reference 1 should be adequate for tha t group (I hope). Missing Referen ce 5 apparently pertains to military a i rcraft crashes. I think that recent submlttals rely on guidance in a DOE standard that we have. Reference 5 I s cited I n SRP 2.2.1-2.2.2 , so that's why i t Is on the list. Mi ssing Referen ce 8 apparently perta i ns to gasoline barge accidents. I think that the PSEG ESP probably contains more recent methods. Reference 8 is cited in SRP 2.2.1-2.2.2 , so that's why it is on the list. 1/'4 4/171201 8 R E: R e: Update on Elusi ve Reference s. M e n-Made Hazard s Missing Refe r ence 1 2 i s a mystery. It I s ci t e d i n SRP 2.2.3 , but I have no i dea what types o f haza r ds I t might ad d ress. It's too o l d and too nebulous to J ustify mor e effort. So , I th i nk we now have enough.

3 were found In either print or on microfiche

-the microfiche addresses are included on the list. If you need help for some reason, Sardar Zuberi of the PDR found those for me So, what Dennis and John need are electronic versions of these. I guess a two-step process Is required, copying and/or downloading the hard copies available, and then scanning those into an e-version. The members have asked for this as they are trying to work In a paperless environment.

If you think you will need some help as the scanning might be labor intensive, please ask Mark and Alesha who you could solicit for aid. As far as timing -I think having these available within the next 2 weeks should be good. Send them to me when they are ready e-versions as I will package all of the documents we found into one email , to minimize confusion.

Let me know if you have any questions.

I am work i ng on the " External Man-Made Hazards" report (currently with John and Dennis), and they have asked me to locate and make ava i lable to them about a dozen refer ences from the Standard Review Plan and a couple of Reg Gu i des. The se references are, for the most part, very old, and such have never been added to ADAMS In e l ectronic form. Most of them are, however , showing up In the ADAMS " Legacy Library" or In ancjent Docket Files (for example , an affidavit from an NRC employee on the Skag i t Nuclear Power Plant license I) The Technical Library is running them down for me , and i s nearly fin i shed. Of the dozen, it turns out three of them have been located In e l ectronic format , so I have down l oaded those. What will probab l y be needed for the other Nine is a hard copy will need to be made , and that Is where I will need your help. Have you ever used a NUDOCS station? These old references will be found i n microfiche form. When the Tech Library is done, t hey will provide the microfiche addresses for them all , and then somebody has to sit at a NUDOCS station and make the hard copy. It i s very tedio u s , b ut I found it v ery fun (in the old daysl). I think there will be a couple of microfiche that will be found in the NUDOCS station In the Technical Library , and then the re s t will be in the NUDOCS s tation In the public document room. I will let you kn o w when the Library I s done with the resear c h. Let m e know if t h i s sounds like (a lso y ou Mark) something somebody else m i ght like to (or shou l d) do.

• The loader of the film ... the wheels had some drift at points so I may have repea t ed slldes but I think my system of captures was the best tradeoff of speed and accuracy.

Sorry In advan ce I

• On the a l bum of the microfilm, I have to save each individua l page. Also, each page was NOT ID'd. Rcr 11-I think I captured a Livermore page. This address was not correct! TL; DR-Ug l y, but I got done what was possible given physical const r aints.

Acceptance for Referencing of Licensing Topical Report Titled, "Guidelines for Pennanent BWR Hydrogen Water Chemistry Installations," 1987 Revision

Dear Mr. Neils:

We have completed our review of the topical report submitted by your letter dated December 5, 1986, We find the report acceptable for referencing in licensee requests for approval of permanent hydrogen water chemistry installation to the extent and under t~e limitations delineated in the repC'rt and the associated NRC evaluation, which is enclosed.

The evaluation defines the basis for acceptance of the report. We do not intend to repeat our review of the matters described in the report and found acceptable when the report is referenced in licensee requests for approval of a permanent hydrogen water chemistry installation, except to ensure that the material presented is applicable to the specific plant involved.

Our acceptance applies only to the matters described in the report. In accordance with procedures established in NUREG-0390, we request that EPRI publish accepted versions of this report within three months of receipt of this letter. The accepted versions should incorporate this letter and the enclosed evaluation between the title page and the abstract.

The accepted version should include an -A (designating accepted}

following the report identification number. Hydrogen water chemistry in combination with high water quality has demonstrated that mitigation and possibly complete suppression of intergranular stress corrosion cracking can be achieved in 280°C water at an electrochemical potential of less than -230 mV {Standard Hydrogen Electrode).

This can be achieved with a dissolved oxygen content below 20 ppb and the conductivity maintained below 0.3 µS/cm. Consequently, the staff is developing criteria to give credit for effective hydrogen water chemistry in reducing frequency of inservice inspection of recirculation piping. There have been a number of recent potentially hazardous hydrogen concentrations and/or deflagrations resulting from hydrogen leaks (NRC Infonnation Notice No. 87-20: Hydrogen Leak in Auxiliary Building).

When this topical report is revised to.incorporate our evaluation, it may also be useful in providing industry guidance for the design, operation, maintenance.

surveillance, and G. Neils testing of hydrogen supply systems (1) for providing a cover gas in the PWR volume control tank and (2) for cooling the generator (in addition to hydrogen water chemi~try).

We recommend that you consider providing such guidance in the final version. Sincerely.

Status of Man-Made Externa l Hazards Working Group During the reporting of the Planning and Procedures Subcommittee (P&P) at the 628 1 h full Committee Meeting I took an action Item to be the staff engineer for a working group on man-made external hazards. l noted that the Members of this working group are the addresses of this email. We discussed during the P&P that consideration of man-made external hazards was specifically excluded by the NRC staff during their consideration for resolving open Fukushima Tier 2 and 3 recommendations. More specifically.

the NRC staff stated In the draft Tier 2 and 3 SECY that , " Because man-made hazards do not have a direct nexus to the Fukushima Oai-ichi accident, the staff concluded that they should be treated outs i de the scope of Fukushima lesson-learned activities. As such , the NRC staff submitted the consideration of man-made hazards to the NRC's Generic Issue (GI) program by memorandum dated September 9 , 2013 (ADAMS Accession No. Ml12328A180). By memorandum dated January 17 , 2014 (ADAMS Accession No. ML13298A782), the NRC staff concluded that the proposed GI does not satisfy at least three criteria for acceptance as a GI. Therefore , the NRC staff did not undertake possible regulatory requirements or infonnation collection related to man-made hazards and will continue to address i ssues i n that area as they arise on a case-by-case basis, as has been the NRC's historica l pract i ce.* Attached please find the staffs evaluation of the proposed GI. Please note it is not publlcally available and treat it accordingly. The s1aff ooncludes in its evaluation that several regulations are potentially gennane to the issue of Increased risk due to man-made external hazards. Accordingly, NRC may inspect in this area, and may prompt further evaluations (either by Individual plants or generically

), as appropriate. Slmllarly, regulatory processes are available to address FSAR updates of new information. So the staff is say i ng that If they are made aware of information that would potentially negate a licensee screening out a man-made hazard they could pursue IL I think the next step is to determine if we have sufficient Information to question the screening of certain man-made hazards and then determine how best to communicate this with the NRC staff (What is the most germane regulation or regulatory process for this issue. Perhaps enhanced guidance on consideration of the new data in the RG). Finally , please note that the Paul Blanch letter of October 1 , 2015 that was shared with the Committee at P&P on this issue is noo-pubUcaUy available. It should not be shared outside the Committee. I look forward to further direct i on from the working group.

Subject:

Preliminary Research on Natural Gas P ipeline Explosions I am sending this to you because I :hlnk you are the members interested in the White Paper the Committee wants to develop on natural gas pipeline Incidents. (Remind me 1 f there are others and I will send to t hem!) I have done some preliminary r esearch on natural gas pipeline explosions and vetted some of the i nf orma t ion that is available.

The Internet yields websites and sources where there Is Da t a, and where there is anecdotal information.

The most comprehensive data on pipeline explosions 1s kept by the Pipeline and Hazardous Mate r ial Sa fety Administration (PHMSA), part of the Department of Transportation.

The data he re seems fairly comprehensive back to 1994 and individualized reports can be made sorting o n pipeline types, allowing one to remove gasoline and crude oil pipel i ne incidents from natural gas Incidents, for example. Maybe some other playing around would result i n even more specialized reports. As one would expect, the data concentra t es on deaths and Injuries from the inci d ents, as well as proper ty damages. I don't have an understand i ng yet of when and/or why an incident would or would not be reportable to the PHMSA, although i t appears as if ALL incidents must be r eported If there is either death or i njury. The N a t ional Transportation Sa f ety Board (NTSB) 1s called In on many occasions (I had not pa id attention to this before) to investigate the causes of pipeline incidents. I h ave not done enough discovery to learn w hen and/or why they would be asked to investigate (versus not asked). But a q uick search yielded so me 120 indivi dua l reports on pipeline Incidents of all k ind s. I did not d ig deeper to see how many are natural gas reports, but a quick look seems t o indicate there are several. T he San Bruno 2010 incident ,s one that NTSB Inves t igated and I downloaded that report to r ead. Anecdotal information, mo stly in the form of Newspaper art i cles, Is readily available from several sou r ces, Including Wlklpedla, as well as "WatchdogN groups (e.g., Natural Gas Watch) w hich can be used to supplemen t data sources, if desired. As I said, not understand i ng yet when and/or why a n incident wou l d or w ould not be reportable to a government agency, I figure not all pipeline I nciden t s are reported, I don't know how many of the anecdo t al discussions are "repeats" of the data until more work is completed

-if we go that route. So th at is a fast 10,000-foot l evel look.

• Master meter & petroleum gas operators exem p t (un l ess transports gas as primary a c tivity).

Public Awareness Regulations

§ 192.616/ §195.440 Public Awareness d)* Program must specifically include provisions to educate the public, appropriate government organizations, and persons engaged in excavation related activities on: ( 1 ) Use of a one-call notification system prior to excavation and other damage prevention activities; (2) Possible hazards associated with unintended releases from a pipeline facility; (3) Physical indications that such a release may have occurred; (4) Steps that should be taken for public safety in the event of a pipeline release; and (5) Procedures for reporting such an event.

• Master meter & petroleum gas operators exempt (unless transports gas as primary activity).

Public Awareness Regulations

§ 192.616/ §195.440 Public Awareness e)

• Program must include activities to advise affected municipalities, school districts, businesses, and residents of pipeline facility locations.

f)

• Program and the media used must be as comprehensive as necessary to reach all areas in which the operator transports gas. g)

• Program must be conducted in English and in other languages commonly understood by a significant number and concentration of the non-English speaking population in the operator's area.

• Master meter & petroleum gas operators exempt (unless transports gas as primary activity).

Public Awareness Regulations

§192.616/

§195.440 Public Awareness h) Operators in existence on June 20, 2005, must have completed their written programs no later than June 20, 2006 (June 13, 2008 for master meter or petroleum gas system operators}.

i) Program documentation and evaluation results must be available for periodic review by appropriate regulatory agencies.

• Master meter & petroleum gas operators exempt (unless transports gas as primary activity).

Public Awareness Regulations

§ 192.616/ §195.440 Public Awareness j) Unless the operator transports gas as a primary activity, master meter or petroleum gas system operators are not required to develop a public awareness program as prescribed in paragraphs (a) through (g). Instead must develop and implement a written procedure to provide its customers public awareness messages twice annually.

The message must include: 1) A description of the purpose and reliability of the pipeline 2) An overview of the hazards of the pipeline and prevention measures used; 3) Information about damage prevention;

4) How to recognize and respond to a leak; and 5) How to get additional information.

Section Four How effective is the operator's public awareness program?

• Collecting data is not the o*nly component to completing an effectiveness evaluation.

• Operator effectiveness evaluations should:

• Identify program metrics

• Describe evaluation methodology

• Summarize findings or conclusions

• Identify changes in written plan and/or implementation Conclusion

• Most operators putting forth effort and improving programs with creative approaches

• Process/methodology improvements are needed with annual audits/effectiveness evaluations

• Motivating stakeholders to stop, listen, and change

• Balancing information overload with specific messages Gathering Pipelines

• What is a gathering pipeline?

>>,, transport ga s e s and liquid s from the commodity' s source -to a proce ss ing facility , refinery or a transmis s ion line.

• Gathering lines are defined as: }> For natural ga s, a pipeline that transp o rts ga s from a current productior:i facility to a transmi ss ion line o r main (49 CFR 192.3) a s determined using an indu s try s tandard (49 CFR 192.8). F o r hazardous liquid s, a pipeline 219.1 mm (8 5/8 in) o r le ss in nominal o utside diameter that tran s p o rt s petroleum from a production facility (49 CFR 19 5.2).

Gas Gathering

• §192.8 How are onshore gathering lines and regulated onshore gathering lines determined?

> An operator must use API RP 80 (incorporated by reference, s ee §192. 7), to determine if an on s hore pipeline (or part of a connected s erie s of pipeline s) is an on s hore gathering line. The determination is s ubje c t to the limitations listed below. After making this determination, an operat o r mu s t determine if the on s hore gathering line i s a regulated onshore gathering line under paragraph (b) o f thi s s ection. (Type A or B)

Gas Gathering

• §192.9 What requirements apply to gathering lines? , Off s hore ga s gathering pipeline s and highpre ss ure on s hore line s (Type A) must meet all requirement s of 49 CFR192 applicable to ga s transmi ss ion pipeline s. On s h o re gas gathering pipeline s that o pe r ate at lower pre ss ures (Type B) mu s t c omply with a s ubset of the s e requirements s pecified in 49 CFR 192.9.

,. Liquids Gathering

• §195.11 What is a regulated rural gathering line & what requirements apply? A regulated rural gathering line means an onshore gathering line in a rural area that ha s: a nominal diameter from 6 5/8 inche s (168 mm) to 8 5/8 inche s (219.1 mm); is located in or within one-quarter mile (.40 km) of an unu s ually s en s itive area a s defined in §195.6; and operate s at a maximum pre ss ure corre s ponding to a s tre ss level greater than 20-percent of the s pecified minimum yield strength of the line pipe; or if the s tre ss level i s unknown or the pipeline i s not constructed with s teel pipe, a pre ss ure of more than 125 p s i (861 kPa) gage.

Damage prevention program. External corrosion control for steel pipelines. Internal corrosion prevention and mitigation for steel pipelines. Operator Qualification.

-7 6-Gathering Pipelines

• If regulation is eventually extended to all onshore gathering pipelines, who will be in charge of regulating them? Mo s t onshore gathering pipelines begin and end in the s ame s tate. While PHMSA i s resp o n s ible for conducting in s pections o n pipeline s that c ro ss s tate boundarie s, individual s tate s' w/c ertified pipeline s afety agencie s govern line s that do not. Intra s tate pipeline s are regulated by the s e agencie s through adoption and enforcement of PHMSA Federal s afet y s tandards. PHMSA's r o le i s to o versee s tate agen cy performance. The State maintains direct regulatory authority , but must maintain Federal Regulations.

Ref: q ues t ion on gas pipelines around IP Hell o Br ian, Sarah and Garrett , I am he lp ing the ACRS staff gather informat i on on man-made hazards at nuclear plants ,

with particular Interest In gas p i pelines that are existing or being purposed In the vicin i ty of a nuclear facility. It is my understanding that Indian Po i nt has had this Issue and came to some conclusion.

If you could verify this for me and direct me to any analysis they produced to support the i r posit i on would be greatly app r eciated. Sincerely, Ev elyn Gettys Project Manager ACRS (R) 301-415-4029 TWF-D41 Natural Gas Pipeline Project Proposed Near Indian Point Key Messages

• On March 3 , 2015 , the Federal Energy Regulatory Commission (FERC) approved the proposed Spectra Energy expansion to natural gas pipelines In the New England area. If constructed, a new 42-inch diameter p i peline will traverse a portion of the controlled property at the Ind ian Point site.

• Entergy Nuc lea r Operations, Inc. performed a site hazards analysis of the new pipeline pursuant to 1 O CFR 50.59 and concluded that the project poses no additional risks and that prior NRC review and approval Is not required.

• NRC staff from Region I , NRO , and NRR reviewed Entergy's 50.59 evaluation, performed an Independent blast analysis, and concluded that the proposed natural gas pipeline will not pose additional risks to radiological safety at the Indian Point site. Facts

• Natural gas pipelines have existed on the Indian Point owner-controlled property prior to plant construction. A 26-inch diameter natural gas pipeline was built In 1952, followed by a 30-lnch diame te r pipeline In 1965. Operating licenses were granted to Indian Point Units 1 , 2, and 3 in 1962, 1973, and 1975 , respectively. The existing pipelines are located approximately 640 feet from the Un it 3 containment.

The AEC/NRC performed confirmatory analysis to determine the impact of a rupture of the existing natural gas pipelines at the Indian Point facility in 1973 , 2003 and 2008.

• NRC regulations require that the licensee perform a site hazards analysis to determine the Impact of a rupture of the proposed natural gas pipeline on the safe operation and shutdown of nu clear power plants. Entergy submitted their analysis concluding that a rup , ture of the 42-inch natural gas pipeline would not represent an increased risk of rad iolog ical safety at the site and that prior NRC review and approval was not requi red.

• While the new pipeline is larger than the existing pipelines, it will be routed significantly further away from safety-related systems , structures, and components (SSCs) than the existing gas pipelines at the Indian Point site. The c losest distance from the underground piping to the security owner controlled area fence is 1580 ft. As a result , the blast analys i s performed by the licensee and the confirmatory analysis performed by the NRC concluded tha t resultant pressure waves and critical heat flux from a pipeline rupture would not adversely impact SSCs at the site.

• Both the licensee and the NRC used the ALOHA computer code for the blast analysis.

ALOHA , which was developed by EPA and NOAA, is designed to model chemical releases and Is widely accepted by numerous industries. Release rates determined by ALOHA have been compared with release rates calculated manually based upon equations available in reference li terature and reports. The ALOHA model predicts maximum and average release rates that are h i gher than the ones calculated by hand and, therefore, is considered rea sonable and conservative for this application.
