Measures to reduce pollutant loadings shall be evaluated to determine whether they are adequate and properly implemented in accordance with the terms of the permit or whether additional control measures are needed. Structural stormwater management measures, sediment and erosion control measures, and other structural pollution prevention measures identified in the plan shall be observed to ensure that they are operating correctly. A visual inspection of equipment needed to implement the plan, such as spill response equipment, shall be made.

b. Based on the results of the inspection, the description of potential pollutant sources identified in the PPC plan, and pollution prevention measures and controls identified in the plan shall be revised as appropriate within 15 days of such. inspection and shall provide for implementation of any changes to the plan in a timely manner, but in no case more than 90 days after the inspection.

D. Stormwater Sampling and Reporting

1. Ail samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inches in magnitude and that occurs at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> from the previously measurable (greater than 0.1 inches) storm event.

2. When the discharger is unable to collect samples due to adverse climatic conditions, the discharger, must submit, in lieu of samipling data, a description of. why samples could not be collected, including available documentation of the event.. This'sampling waiver may not be used more than once during a two0-yea period.

3. Grab samples shall be collected during the first 30 minutes of the discharge.

4. Stormwater monitoring results shall be summarized on a DMR form and the Department's "Additional Information for the Reporting of Stormwater Monitoring" form.

5. When a facility has two or more outfalls that may reasonably be believed, to discharge substantially identical effluents, based on a consideration of features and activities within the area drained by the outfall, the permittee may sample one such outfall and report that the quantitative data also applies to the substantially identical outfalls.

6. The following table describes the outfall locations and drainage areas.

EnvironmentalReport Appendix B CLEAN WATER A CT DOCUMENTATION Discharge Monitoring Reports & Supplemental Report Forms

" *(Instructions and helpful hints for their completion)

Please find attached your Discharge Monitoring Report (DMR) and Supplemental Report forms. These forms are used in the self-monitoring program as required by your NPDES permit. You should make copies of these forms for your use.

The reporting period is generally a calendar month. Your reports must be received by the 28th day of the following month.

Please see that all treatment facility personnel are aware of the permit and DMR form. We seek your assistance in preventing errors and reporting mistakes.

DISCHARGE MONITORING REPORTS (DMRs)

. Inspect the form and contact us immediately if you find errors or omissions. Do not change or add information yourself.

. Complete all blocks where we have listed an entry under Permit Condition. This includes the FREQUENCY OF ANALYSIS and SAMPLE TYPE columns. Do not complete any other blocks.

Make sure your reports are neat and legible. Submit original DMR, signed in ink to DEP.

Report in the same significant figures as shown on Effluent Limitations, Monitoring, Recordkeeping, and Reporting Requirements page.

• Report in the same units shown on the DMR.

• List the number of times a particular permit condition has been exceeded under the NO EX column. This would include daily, Weekly, and monthly limitations. If there were none for that month, enter zero (0). This does not apply to flow.

• If there was no discharge for a particular outfall, a DMR must still be submitted. Write "NO DISCHARGE" on the FLOW line or on the first parameter line if FLOW is not listed.

• If a particular parameter is conditional on other parameters (such as FLOW or TEMPERATURE), it may not always be reportable. If this is the case, write "NO DISCHARGE" on that parameter line and provide an explanation.

If you have quantity limits (loadings) listed on the DMR, you will need to calculate the quantity in lb/day. To do this, use the following formula:

mg/I (concentration) x MGD (Flow) x 8.34 Ib/gal = lb/day The monthly average lb/day is the sum of all the daily lb/day results divided by the number of days you sampled.

Do not use monthly average flow and monthly average concentration in the above formula:

All effluent samples taken using approved methods must be recorded on the Supplemental form and reported on the DMR.

For every day you sample the effluent, you should record the sample result for that day. The discharge flow should be recorded in million gal/day for that day, (a 24-hour period). Use these figures to calculate the lb/day in the formula above.

Use > (greater than), < (less than) - the method detection limit to report results that are above or below the detection limit and cannot be quantified. Use the method detection limit for calculating loadings if values are less than detection limit.

http://www.dep. state.0a.us/dep/deputate/wateroos/hdex.htm Enter the site and click on: Water/Wastewater Calculators.

Supplemental Form (W)

This form is used for many industrial dischargers and in conjunction with Supplemental Form (S) for some sewage facilities. The column headings in Form (W) are matched to individual permit requirements.

• Flow. Report in million gallons (MG). For example: 13,000 gallons= 0.013 MG; 7,500 gallons = 0.0075 MG; 540 gallons.= 0.00054 MG; if no flow, indicate by printing "NO FLOW".

• Total Suspended Solids (TSS). Report TSS concentration (mg/I) and quantity (lb/day).

• pH. Record the pH of the effluent.

• Report' effluent parameters at least as often as specified in the permit. Report any influent and process control

.data as you perform them.

You may use a computer-generated report for the Supplemental DMR only. Please use the same format as ours.

Please contact this office concerning use of your own forms.

Indicate any outside laboratory use at the bottom of the form. Mark with an X if all of the testing is done in-house at your facility.

Please do not send laboratory report forms from your testing laboratory. Do not send your bench sheet or other records, which should be kept at your facility.

• There are a great number of possible column headings for Form (W). Let us know if the abbreviations used are not clear.

We ask that you call us immediately in the event of any equipment breakdown, chemical spilli or shock loading to your influent. Call us also if operational problems result in a failure to achieve your treatment requirements. This includes treatment facility bypasses, pump station failures, and collection system overflows. Violations of.effluent limitations for toxic constituents should also be reported. A Written report should follow within five (5) days of the event. Refer to your permit for acomplete description of the monitoring and reporting responsibilities.

NON-COMPLIANCE DISCHARGE REPORT FORM Included with the DMR Supplemental Form is a Non-Compliance Discharge Report Form. This form, when, property completed, will suffice as the five-day letter as required in the permit. The following sections must be completed:

1. Describe what was discharged (sludge, raw influent, bypass, etc.) and the date(s) the non-compliance occurred.

2. Circle the applicable stream effects, or describe any unlisted impacts.

3. Explain the cause of the non-compliance. Use the reverse side of the paper or attach additional pages as necessary.

.4. Fill in the date(s) and time(s) of the event. Indicate when the event will cease.

5. List here what has been done to reduce, eliminate, and prevent a recurrence bf the non-complying discharge.

6. List here any special analyses performed and/or field tests conducted on thedischarge and/or stream.

7. When and who did you notify of the non-complying discharge.

8. Your signature and title.

SUBJECT:

Three Mile Island Nuclear Station Unit I License Renewal. Request for information on state-listed threatened and endangered species and

-important habitats (plants)..,

Dear Ms. Firestone:

AmerGen is preparing an application for the U. S. Nuclear Regulatory Commission (NRC) to renew the operating license for Three Mile Island Nuclear Station Unit I (TMI-1). The current operating license for TMI-1 will expire in 2014. The renewal term would be for an additional 20 years beyond the original license expiration date. As part of the license renewal process, the NRC requires license applicants to "assess the impact of the proposed action on threatened or endangered species in accordance with the Endangered Species Act" (10 CFR 51.53). The NRC will also request an informal consultation with your office at a later date under Section 7. of the Endangered Species Act. By contacting you early in the application process, we hope to identify any issues that we need to address or any information that we should provide to your office to expedite the NRC consultation.

TMI-1 is located on Three Mile Island, in the Susquehanna River, in the Londonderry Township of Dauphin County, Pennsylvania. AmerGen began operations of TMI- 1 after its purchase of the facility in 1999. The transmission lines associated with the facility are owned and operated by First Energy Corporation. Four transmission lines. connect the station to the regional grid, and are thus relevant to license renewal. The Final Environmental Statement for operation prepared in 1972 by the U.S. Atomic Energy Commission identified three 230-kilovolt (kV) transmission lines that were built to connect Unit I to the electric grid. Two of these 230-kV lines span northeast approximately 1.4 miles in the same corridor connecting the plant with the substation at Middletown Junction. The third 230-kV line extends for 4.1 miles to the western side of the Susquehanna River connecting with the Jackson Substation near Cly. Subsequent to the publication of the Final Environmental Statement, a fourth 230-kV line was also constructed that extends 0.7 miles southeast to the TMI-l 500-kV substation. All of the transmission lines are within 150-foot wide corridors Three Mile Island Nuclear Station Unit I Page.C-I License Renewal Application

Environmental Report Appendix C SPECIAL STATUS SPECIES CORRESPONDENCE May 22; 2007 Page 2 of 2 and are primarily in agricultural or pasture lands that continue to be cultivated. Included is a map of the transmission line system layered over the USGS topographic maps surrounding the TMI-I facility (see Figure 1). Pennsylvania counties crossed by the transmission lines include Lancaster, Dauphin, and York. AmerGen is not aware of any state-listed plant species at TMI or along the TMI-associated transmission lines, with the exception-of the American holly (Hex opaca), which was identified on TMI as part of Exelon's cominitinent to the environment under the Wildlife Habitat Council program.

A review of the Pennsylvania Natural Heritage Program web site for state-listed endangered or threatened species indicates that numerous state-listed plant species have been recorded in the counties crossed by the transmission lines; however, a large percentage of these plants have been recorded in Lancaster County and TMI-1 transmission lines only cross a very small section of Lancaster County in the extreme western comer (see Figure 1). First Energy.

maintains the transmission lines and ensures adherence to regulatory requirements regarding sensitive areas that could contain threatened or endangered species as well as state-listed species and works closely. with your department.to ensure protection of these sensitive'areas.

AmerGen is committed to the conservation of significant natural habitats and protected

.species, and -expects that operation of TMI-1, including maintenance of. the identified transmission lines, through the license, renewal period (an additional 20 years) would not

.:adversely affect any listed species. AmerGen has no plans to a'lter current operatidns over the license renewal period:. Any maintenance activities necessary to support license renewal would be limited to previously disturbed areas.

In addition, AmerGenplans to replace the existing steam generators with newer models in the fall of 2009. These replacement activities would occur within the existing Unit .1 containment structure. A 6,000 square foot- dedicated storage facility would be built within the existing industrial footprint of the site to house the old steam generators. No additional land disturbance is anticipated in support of license renewal.

Please call Fred Polaski (610) 765-5935 if you have any questions or require any additional information. After your review, we would appreciate receiving your input by August 17, 2007, detailing any concerns you may have about any listed species or critical habitat in.the area, or confirming AmerGen's conclusion that operation of TMI-I over the license renewal.

term would have no effect on any threatened or endangered species. This will enable us to meet our application preparation schedule. AmerGen will include a copy of this letter and your response in the Environmental Report that will be submitted to the NRC as part of the TMI-1 license renewal application.

Dear Mr. Gallagher,

This responds to your request about a Pennsylvania Natural Diversity Inventory (PNDI) ER Tool "Potential Impact" or a species of special concern impact review. We screened this project for potential impacts to species and resources of special concern under the Department of Conservation and Natural Resources' responsibility, which includes plants, natural communities, terrestrial invertebrates and geologic features only.

PNDI records indicate that species and communities of special concern under DCNR's jurisdiction are known to occur in the vicinity of the above-mentioned project. Please see the attached list for species found in the project area. If any earth disturbance is planned or more detailed project information becomes available, please submit this project to our office for further review of potential impacts to the attached species list.

This response represents the most up-to-date summary of the PNDI data files and is good for one (1) year fiom the date of this letter. An absence of recorded information does not necessarily imply actual conditions on-site.

A field survey of any site may reveal previously unreported populations. Should project plans change or additional information on listed or proposed species become available, this determination may be reconsidered.

This finding applies to impacts to plants, natural communities, terrestrial invertebrates and geologic features only. To complete your review of state and federally-listed species of special concern, please be sure the U.S.

Fish and Wildlife Service, the PA Game Commission and the Fish and. Boat Commission has been contacted regarding this project either directly or by performing a search with the online PNDI ER Tool found at wv.naturalherita e.state,pa.us.

SUBJECT:

Three Mile Island Nuclear Station Unit I License Renewal. Request for information on state-listed threatened and endangered species and important habitats (fish, reptiles amphibians, and invertebrates).

Dear Mr. Urban:

AmerGen is preparing an application for the U. S. Nuclear Regulatory Commission (NRC) to renew the operating license for Three Mile Island Nuclear Station Unit 1 (TMI-1). The current operating license for TMI-I will expire in 2014. Therenewal term would be for an additional 20 years beyond the original license expiration date. As part of the license renewal process, the NRC requires license applicants'.to "assess the impact of the proposed action on threatened or endangered species in accordance with the Endangered Species Act" (10 CFR 51.53). The NRC will also request an informal consultation with your office at a later date under Section 7 of the Endangered Species Act. By contacting you early in the application process, we hope to identify any issues that we need to address or any information that we should provide to your office to expedite the NRC consultation.

TMI-1 is located on Three Mile Island, in the Susquehanna River, in the Londonderry Township of Dauphin County, Pennsylvania AmerGen began operations of TMI-I alter its purchase of the facility in 1999. The transmission lines associated with the facility are owned and operated by First Energy Corporation. Four transmission lines connect the station to the regional grid, and are thus relevant to license renewal. The Final Environmental Statement for operation prepared in 1972 by the U.S. -Atomic Energy Commission identified three 230-kilovolt (kV) transmission lines that were built to connect Unit I to the electric grid. Two of these 230-kV lines span northeast approximately 1.4 miles in the same corridor connecting the plant with the substation at Middletown Junction. The third 230-kV line extends for 4.1 miles to the western side of the Susquehanna River connecting with the Jackson Substation near Cly. Subsequent to the publication of the Final Environmental Statement, a fourth 230-kV line was also constructed that extends 0.7 miles southeast to the TMI-1 500-kV substation. All of the transmission lines are within 150-foot wide corridors Three Mile Island Nuclear Station Unit 1 Page C-7 License Renewal Application

Environmental Report Appendix C SPECIAL STATUS SPECIES CORRESPONDENCE May 22, 2007 Page 2 of 2 and are primarily in agricultural or pasture lands that continue to be cultivated. Included is a map of the transmission line system layered over the USGS topographic maps surrounding the TMI-1 facility (see Figure 1). Pennsy]vania counties crossed by the transmission lines include Lancaster, Dauphin, and York. Based on our direct observations, a review of TMI-1 records, and a review of the Pennsylvania Natural Heritage Program web site for state-listed endangered or threatened species, AmerGen believes that a complete list of state-listed threatened and endangered species has been compiled. This species list includes: three reptiles (Bog turtle, Clemmys muhlenbergii,Rough green snake, Opheodrys aestivus, and the Redbelly turtle, Pseudemys rubriventris);one fish (Black bullhead, Ameiurms melas) and one invertebrate (Dwarf wedgemussel, Alasmidonta heterodon), that could occur in the counties crossed by the transmission lines.

AmerGen is committed to the conservation of significant natural habitats and protected species, and expects that operation of TMI-1, including maintenance of the identified transmission lines, through the license renewal period (an additional 20 years) would not adversely affect any listed species. AmerGen has no plans to alter current operations over the license renewal period. Any maintenance activities necessary to support license renewal would be limited to previously disturbed areas.

In addition, AmerGen plans to'replace the existing steam generators with newer models in the fall of 2009. These replacement activities would occur within the existing Unit I containment structure. A 6,000 square foot dedicated storage facility would be built within the existing industrial footprint of the site to house the old steam generators. No additional land disturbance is anticipated in support of license renewal.

Please call Fred Polaski (610) 765-5935 if you have any questions or require any additional information. After your review, we would appreciate receiving your input by August 17, 2007, detailing. any concernis you may have about any listed species or critical habitat in the area, or confirming AmerGen's conclusion that operation of TMI-1 over the license renewal term would have no effect on any threatened or endangered species:' This will enable us to meet our application preparation-schedule. AmerGen will include a copy of this letter and your response in the Environmental Report that will be submitted to the NRC as part of the TMI- I license renewal application.

Sincerely, Michael P. Gallagher

Dear Mr. Gallagher:

This responds to your letter of May 22, 2007, requesting information about federally listed and proposed endangered and threatened species within the area affected by the Three Mile Island Nuclear Station Unit I License Renewal, located in Lancaster, Dauphin and York Counties, Pennsylvania. The following comments are provided pursuant to the Endangered Species Act of 1973 (87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.) to ensure the protection of endangered and threatened species.

A nest of the federally listed, threshold bald eagle (Haliaeetusleucocephalus) is located on the west side of the Susquehanna River.to the northwest of the proposed project. Based on the nature and scale of project activities, and the distance of these activities from the nest, we do not anticipate that bald eagles will be adversely affected.

The Fish and Wildlife Service proposed to remove the bald eagle from the federal List of Endangeredand Threatened Wildlife on July 6, 1999 (FederalRegister, Vol. 64, No. 128), but final action on that proposal has not been taken. Therefore, the bald eagle continues to be listed under ihe Endangered Species Act. Any changes in the regulatory status of the bald eagle can be monitored by accessing our web site at http://wwvw.fws.gzov/migratorybirds/baldeagle.htm.

If the bald eagle is delisted, it will no longer receive protection under the Endangered Species Act, but it will continue to be protected by the Bald and Golden Eagle Protection Act (Eagle Act) and the Migratory Bird Treaty Act (MBTA). Both acts protect bald eagles by prohibiting killing, selling or otherwise harming eagles, their nests or eggs. The Eagle Act~also protects eagles from disturbance.

On June 4, 2007, the Service released several important documents related to the protection of bald eagles under the Eagle Act, including 1) a final rule establishing a regulatory definition of Three Mile Island Nuclear Station Unit I Page C-19 License Renewal Application

Environmental Report Appendix C SPECIAL STATUS SPECIES CORRESPONDENCE "disturb"; 2) a final environmental assessment of the "disturb" regulation; 3) National Bald Eagle Management Guidelines; and 4) a proposed rule to establish a permit for the take of bald and golden eagles. The proposed rule would establish regulations for issuing permits to take bald and golden eagles where the take is associated with, and not the purpose of, otherwise lawful.-

activities. A second permit type would provide for permits to take bald and golden eaglenests for safety emergencies (of humans or eagles). All of these documents can be found at the web site referenced above.

Based on our review of the proposed project, it is our determination under the Endangered Species Act that this project is not likely to adversely affect bald eagles. It is also our determination under the Eagle Act that this project will not disturb bald eagles. Because no take or disturbance.is anticipated, none is authorized. If project plans change, please contact the.

Service to determine whether or not the project modifications will result in effects to bald eagles that may necessitate an Eagle Act permit or Endangered Species Act authorization. " .

Three Mile Island Nuclear Station Unit 1 License Renewal. Request for Information on Thermophilic Microorganisms.

Dear Mr. Aunkst:

AmerGen, is preparing an application to the U.S. Nuclear Regulatory Commission (NRC) to renew the operating license for Three Mile Island Nuclear Station Unit I (TMI-1). The current operating license for TMI-1 will expire in 2014. Renewing the licenses would provide for an additional 20 years of operation beyond the original license expiration date.

The NRC requires license applicants to provide "...an assessment of the impact of the proposed action {license renewal) on public health from thermophilic organisms in the affected water" (10 CFR 51.53). Organisms of concern include the enteric pathogens Salmonella and Shigella, the Pseudomonas aeruginosa bacterium, thermophilic Actinomycetes ("fungi"), the many species of Legionella bacteria, .and pathogenic strains of the free-living Naegleria amoeba.

As part of the license renewal process, AmerGen is consulting with your office to determine whether there is any concern about the potential occurrence of these organisms in the Susquehanna River at the TMI-1 location. By contacting you early in the application process, we hope to identify any issues that we need to address or any information that we should provide to your office to expedite the NRC consultation.

AmerGen began operations of TMI-1 after its purchase of the facility in 1999. The facility is located on Three Mile Island, in the Susquehanna River in the Londonderry Township in Dauphin County, adjacent to Lancaster and York Counties, Pennsylvania (see Figure 1).

TMI-1 uses two natural draft cooling towers to dissipate waste heat from the station's circulating water system. Thernmal modeling conducted by the NRC for the operation of TMJ-1 indicated that the .station's discharge would have a modest impact on downstream river temperatures (0 to 2.0'F, during summer months). The station's National Pol.lutant Discharge Elimination System (NPDES) permit requires continuous temperature monitoring of the circulating cooling water systems effluent before discharge into the Susquehanna River. Recent temperature data from the stations NPDES Discharge Monitoring Reports for 2004, 2005, and 2006 indicate that the 24-hr average maximum temperature was 100.4*F.

Three Mile Island Nuclear Station Unit 1 Page C-21 License Renewal Application

EnvironmentalReport Appendix C SPECIAL STATUS SPECIES CORRESPONDENCE May 22, 2007 Page 2 of 2 Water temperatures of 100°F are well below the optimal temperature range (122*F-140'F) for growth and reproduction of thermophilic microorganisms.

Fecal coliform bacteria are regarded as indicators of other pathogenic microorganisms, and are the organisms normally monitored by state health agencies. The NPDES permit for TMI-1 requires monitoring of fecal coliforms in the station's sewage treatment plant effluent.

Samples are collected once per quarter for fecal coliform analysis and other parameters. The TMI-1 NPDES permit calls for "effective disinfection" to control disease-producing organisms during the swimming season (May I through September 30) and imposes a limit of 200 fecal coliform colonies (geometric average value) per 100 ml sample during this period. The NPDES permit also stipulates that no more than 10 percent of samples tested may contain 1,000 colonies.

Given the-thermal characteristics of the Susquehanna River at the TMI-l thermal discharge and disinfection of the station's sewage treatment plant effluent, AmerGen does not expect station operations to stimulate growth or reproduction of thermophilic microorganisms.

Under certain circumstances, these organisms might be present in limited.numbers in the station's discharge, but would not be expected in concentrations high enough to pose a threat to recreational users of the Susquehanna River.

We would appreciate your relating any concerns you may have about these organisms and potential public health effects over the license renewal term by August 17, 2007, or your confirmation of AmerGen's conclusion that operation of TMI-1 over the license .renewal term would not stimulate growth of thermophilic pathogens. This will enable us to meet our application preparation schedule. AmerGen will include a copy of this letter and your response in the Environmental Report that will be submitted to the NRC as part of the TM]-1 license renewal application.

SUBJECT:

Three Mile Island Nuclear station Unit 1 License Renewal, Request for Information on historic and archaeological resources.

Dear Ms. Cutler:

AmerGen Energy Company, LLC (AmerGen) is preparing an application to the U.S. Nuclear Regulatory Commission (NRC) to renew the operating license for Three Mile Island Nuclear Station, Unit 1 (TMI-1). The current operating license expires in 2014. The renewal term would be for an additional 20 years beyond the original license expiration date. As part of the license renewal process, NRC requires license applicants to ."assess whether any historic or archaeological properties will be affected by the proposed project." NRC may also request an informal consultation with your office at a later date under Section 106 of the National Historic Preservation Act of 1966, as, amended (16 USC 470), and Federal Advisory Council on Historic Preservation regulations (36 CFR 800). By contacting you early in the application process, we hope to identify any issues that need to be addressed or any-information your office may need to expedite the NRC consultation.

AmerGen does not expect TMI-1 operations through the license renewal term (an additional 20 years) to adversely affect cultural resources in the area. Renewal of the TMI-1 operating license does not involve any changes or additions to the plant or transmission line structures.

In addition to normal operations, AmerGen plans to replace the existing steam generators with newer models in the fall of 2009. These replacement activities would occur within the existing Unit I containment structure. A 6,000 square foot dedicated storage faciliiy, would be built within the existing industrial footprint of the site to house the old steam generators.

This storage facility will be separately permitted, and will be located at a location that has previously been disturbed. For this project and any other potential earthworks projects, AmerGen's corporate procedures will ensure the protection of cultural resources.

Three Mile Island Nuclear Station Unit 1 is located in Londonderry Township in. Dauphin County, Pennsylvania, on the northern end of Three Mile Island near the eastern shore of the Susquehanna River. Four transmission lines connect the station to the regional grid, and are thus relevant to license renewal (see Figure 1,.TMI-1 Transmission System).

Three Mile Island Nuclear Station Unit I Page D-1 License Renewal Application - P

• Line No. 1091 - TMI-1 Plant to Middletown Junction - This 230-kV line operated by First Energy Corporation extends north for 1.4 miles in a 150-foot wide corridor to the Middletown Junction Substation near Middletown.

• Line No. 1092- TMI-I Plant to Middletown Junction- This 230-kV line operated by First Energy Corporation extends north for 1.4 miles in a 150-foot wide corridor to the Middletown Junction Substation near Middletown.

• Line No. 1051 - TMJ-l Plant to Jackson Substation - This 230-kV line operated by First Energy Corporation extends southwest for 4.1 miles in a 150-foot wide corridor to the Jackson Substation near Cly, west of the Susquehanna River.

• Line from TMI-I Plant to the 500-kV Substation- This 230-kV line shares the first four towers with the TMI-1 Plant to Jackson Substation line. The line extends southwest for 0.7 miles and connects to the 500-kV Substation.

In total, the transmission lines of interest are contained in approximately 5.5 miles of corridor that occupy approximately 130 acres. The TMI,1 Plant to Middletown Junction lines have adjacent corridors. The corridors pass through land that is primarily agricultural. The areas are mostly remote, with low population densities. Corridors that pass through pastures generally continue to be used as pastures. Each of the lines crosses State Highway 441 after leaving the switchyard. The TMI-I Plant to Jackson Substation line also crosses several smaller roads.

..Using the National Register Information System (NRIS) on-line database, we have compiled a list of sites on the National Register of Historic Places within a six-mile radius of the TMI-1 property. Table I (see attached) details those sites. We will provide, this information to the NRC to aid in its evaluation of the license application.

Additionally, we will notify the NRC of cultural resources investigations of the TMI-l site.that have been performed. In 1967, TMI-l's applicants funded an archaeological survey and subsequent excavation of artifacts from the island prior to construction. The survey and excavation was conducted by the Pennsylvania Historical and Museum Commission (PHMC 1977). More than 1,000 artifacts were found and, from these artifacts, it was deduced that the site had period components ranging from 4,000 B.C. to 1,000+ A.D.

In April, 1987, a paper was presented at the MidAtlantic Archaeological Conference Annual Meeting in Lancaster, Pennsylvania by two archaeologists detailing Work they'd performed in relation to Three Mile Island (Mangold and Grace 1987). The archaeologists wanted to more clearly define the cultural occupations of the island by 1) inspecting extant private collections of those who've collected artifacts from Three Mile Island, 2) reviewing previous archaeological investigations, and 3) performing limited testing on the island. Their investigation led to the conclusion that cultures from the prehistoric Early Archaic through the historic Susquehannock Indians used the island and that much of the cultural data, stratigraphy, and features indicating human activity remain to be investigated.

In 1988, the Curator of Archaeology from the State Museum of Pennsylvania performed an investigation of a burial site discovered on the southern tip of the island by a TMI-1 Page D-2 Three Mile Island Nuclear Station Unit I License Renewal Application

EnvironmentalReport Appendix D STATE HISTORIC PRESERVATION OFFICER CORRESPONDENCE May 21, 2007 Page 3 of 4 employee. The Curator concluded that the human burial was not the product of a recent homicide, but the remains of a 19th century island resident. The remains were collected and later reburied in a location near their original burial sited Associated cultural materials (i.e., clothing buttons, coffin nails, etc.) were collected and donated to the State Museum of Pennsylvania for perpetual curation (Burke 2006).

In 1999, the PHMC held a public history symposium and erected a "historical marker" on State Highway 441, south of the TMI-1 Visitor Center sign, commemorating the 20th anniversary of the TMI-1 Unit 2 accident. The symposium was a cooperative effort of the Pennsylvania Departmnent of Environmental Protection; the Pennsylvania Historical Museum Commission, Pennsylvania State University - Harrisburg, the NRC, GPU Nuclear Incorporated, Three Mile Island Alert, Middletown Borough, and Londonderry Township (PHMC 1999).

Please call Fred Polaski (610) 765-5935, ifyou have any questions or require any additional information. After your review, we would appreciate receiving your input by August 17, 2007, detailing any concerns you may have about cultural resources in the area or .confirming AmerGen's conclusion that operation of TMJ-I over the license renewal term would have no effect on cultural resources. This will enable us to meet our application preparation schedule. ArnerGen will include a copy of this letter and your response in the Environmental Report that will be submitted to the NRC as part of the TMI- I license renewal application.
