DIRECT TESTIMONY OF DAVID T. HARTGEN, Ph.D.,
P.E.,
ON BEHALF OF THE STATE OF NEW YORK REGARDING BOSPITAL EVACUATION TIME ESTIMATES I.
Qualifications and Foundation Q.
Please state your name and occupation.
A.
My name is David T. Hartgen.
I currently am employed by the New York State Department of Transportation as a Principal l
Transportation Analyst.
t l
l Q.
Please provide a brief description of your qualifications.
i A.
My professional career spans approximately 20 years.
Throughout this period, I have developed extensive experience with transportation planning matters, including traffic time l
8804260043 880413 bg])
PDR ADOCK 05000322 T
a estimates nd methods for computing such estimates in an accurate manner.
I also have developed extensive expetience in the field of information systems management.
As part of my duties with the New York State Department of Transportation, I have been responsible for the collection and analysis of transportation statistics pertaining to the State of New York's highways.
I have been directly involved in assessing the performance of various aspects of the State's highway system, including assessing traffic speeds, traffic volumes and highway capacities.
Consequently, I am familiar with the use of sophisticated computerized transportation models.
I have written more than 100 transportation-related articles and reports, more than half of which have been published in various professional journals.
I have served on or chaired over 20 professional panels and committees on transportation issues.
In addition, I am an Adjunct Professor at the State University of New York at Albany, where I assisted in establishing a transportation studies program and where I teach courses related to transportation analysis.
I have been found to be an expert qualified to testify on matters related to evacuation time estimates in two Shoreham j
proceedings:
the 1984 emergency planning hearings and the 1987 reception center hearings I submitted testimony and defended my i
views on cross-examination in both hearings.
As a result of my l
participation in those proceedings, I became familiar with the l
2 l
l t
evidence and testimony sponsored by LILCO and KLD Associates, Inc., concerning evacuation time estimates for Shoreham.
A copy of my resume is Attachment 1 herein.
Q.
What material have you examined concerning LILCO's hospital evacuation time estimates?
A.
I have reviewed portions of Revision 9 of the LILCO Plan pertinent to LILCO's hospital evacuation time estimates, particularly OPIP 3.6.5 and parts of Appendix A of the Plan.
I also have reviewed a stack of hundreds of handwritten worksheets underlying the hospital evacuation time estimates prepared by or under the supervision of Mr. Sobotka (a LILCO consultant) and transmitted to the State of New York under cover of a letter dated February 29, 1988.
Other LILCO Plan materials that I have examined include certain draft revisions to Revision 8, dated February 20, 1987, which were submitted in connection with the 1987 reception center proceedings, and Mr. Lieberman's testimony in that proceeding regarding, in particular, average travel speeds.
In addition, I have reviewed "LILCO's Motion For Summary Disposition of the Hospital Evacuation Issue," dated December 18, 1987; the NRC Staff's response, dated January 15, 1988; the Board's "Memorandum and Order (Ruling on LILCO's Motion for Summary Disposition of the Hospital Evacuation Issue)," dated February 24, 1988; "LILCO's Responses and Objections to Suffolk 3
County's First Set of Interrogatories and Request for Production of Documents," March 10, 1988; and "LILCO's Responses and Objections to Suffolk County's Second Set of Interrogatories and Request for Production of Documents," dated March 10, 1988.
It is important to note, too, that I attended the depositions of Mr. Sobotka and LILCO's expert witness, a principal of KLD Associates, Inc., Mr. Lieberman.
I have read the transcripts of their depositions, as well as the transcript of the deposition of the NRC Staff's expert witnecs, Dr. Urbanik.
1 Q.
Please describe your familiarity with Revision 9 of the LILCO Plan as it pertains to hospital evacuation time estimates?
A.
I am familiar with what the LILCO Plan refers to as an "evacuation strategy" for the three hospitals in or near the EPZ.
Plan, Appendix A, at IV-173.
The actual hospital evacuation time estimates are contained in Table XIIIA (Plan, Appendix A, at IV-184).
LILCO's evacuation ime estimates for each hospital, assuming an evacuation of the full 10 mile EPZ, are:
Inclement Weather Hospital Normal Weather Summer Winter John T. Mather Hospital 12:00 15:42 16:41 Central Suffolk Hospital 12:19 15:52 16:51 St. Charles Hospital 12:20 16:13 17:14 4
-_ herein shows the locations of these hospitals as well as other pertinent facilities.
See also Table XV (Plan, Appendix A, at V-8).
As can be seen from the above results, the longest hospital evacuation time estimate is associated with St.
Charles Hospital, but the evacuation time estimate for Central Suffolk Hospital is just one minute faster.
OPIP 3.6.5 sets forth skeletal procedures for implementing the hospital "evacuation strategy."
Essentially, several LILCO Coordinators are given instructions to evacuate homebound persons I
and persons in health facilities, including hospitals, to reception facilities.
For example, OPIP 3.6.5, Section 5.5.5, instructs the Hospital Coordinator to "assign evacuating patients to reception hospitals listed in Attachment 5" and to "(a]ssign patients requiring ambulances to the reception hospitals closest i
to the EPZ "
Similarly, OPIP 3.6.5, Section 5.6.1, tells the 1
Ambulance Coordinator to "estimate the number of trips the ambulances and/or ambulettes will.need to make."
A list of
)
possible reception hospitals, their addresses and telephone i
numbers is set forth in Attachment 5 of OPIP 3.6.5, but it presents no information at all regarding which hospitals are to receive which patients in which order. herein shows the locations of these reception hospitals.
According to Revision 9 of the LILCO Plan, homebound handicapped persons are evacuated first; health facilities, ordered by proximity to Shoreham, are evacuated second; Suffolk Infirmary is evacuated third; and the three hospitals are 5
evacuated last.
Plan, Appendix A, at IV-178.
Vehicles used to evacuate the hospitals will be provided by the companies who are supplying the vehicles for the evacuation of other segments of the population.
The vehicles consist of a combination of buses, ambulances and ambulettes under contract to LILCO.
The LILCO Plan provides that "[t]hese vehicles will be supplied on an as available basis as the rest of the affected population evacuation nears completion."
Plan, Appendix A, at IV-173.
Therefore, the evacuation of the hospitals is dependent on the prior release of vehicles from their primary responsibilities.
At a site area emergency classification, LILCO would begin the process of mobilizing ambulances and ambulettes at LILCO's facility in Brentwood or Peconic Ambulance Company's facility in Riverhead.
Buses would be mobilized at LILCO's Patchogue facility.
Plan, Appendix A, at IV-176.
Vehicles would then be dispatched from these locations to execute the assignments made by the Hospital and Ambulance Coordinators.
Vehicles would return periodically, as necessary, to Brentwood for reassignment.
The movement of each vehicle involves traveling l
from the applicable staging area to the location of a homebound person or evacuating facility, picking up patients, taking them to reception facilities, unloading them, and then returning to Brentwood for reassignment, and repeating the process, i

II.
Theme of Testimony Q.
What is your general opinion of LILCC s hospital evacuation time estimates?
A.
From the following statement by the Board, it is evident that the Board is interested in knowing whether LILCO's hospital evacuation time estimates can be relied upon ';y LILCO's emergency planners to form the basis of correct protective action recommendations:
(T]he narrow issue of the accuracy of the evacuation time estimates seems to us both unresolved and important.
Clearly both the Appeal Board and the Commission were concerned about these data and their accuracy.
And well they might be for in an emergency, it is on the basis of just such data that responsible officials will need to make fundamental decisions of
~
health ind saf ety for the patients in the hospitals in question.
We therefore will hold a hearing on the matters restricting it to the narrow confines of the bases and the accuracy of the evacuation time estimates presented in Revision 9.
(Emphasis added]
Memorandum and Order (Ruling on LILCO's Motion for Summary Disposition of the Hospital Evacuation Issue), (February 24, 1988) at 12 (emphasis added).
The purpose of this testimony is to demonstrate that LILCO's hospital evacuation time estimates are unreliable because their "accura-is in doubt and their "bases," or underlying assumptions, are questionable in some instances and untenable in others.
It is important to recognize that LILCO's hospital evacuation time estimates are based on a large number of assumptions.
As assumptions fail or fluctuate, LILCO's hospital 7
4 evacuation time estimates also can change accordingly.
LILCO's effort, which could have been and should have been more sophisticated than hundreds of handwritten worksheets, seems to ignore this fundamental traffic planning concept.
Evacuation time estimates that are based on multiple assumptions subject to substantial variation, such as LILCO's hospital evacuation time estimates, are most useful to the personnel charged with implementing the evacuation only if those assumptions hold true at the time of the accident.
If the conditionu (such as traffic speed) prevailing at the time of an evacuation are not in accordance with those assumptions, then LILCO's hospital evacuation time estimates will be substantially inaccurate.
LILCO's Plan does nothing to inform LILCO's personnel how variations in the numerous assumptions may affect evacuation times or affect protective action recommendations.
Further, the Board should be aware that LILCO's hospital evacuation time escimates are based on procedures that appear to be inconsistent with the LILCO Plan.
Thus, for instance, routing and hospital assignment decision made in the worksheets may be totally different in a real emergency. Yet, these decisions have substantial bearing on the overall time estimates.
If the LILCO personnel charged with implementing the LILCO Plan's hospital "evacuation strategy" were to attempt to do so in l
a real emergency, it is questionable whether, given the LILCO Plan's current lack of details, the LILCO personnel would be able to successfully develop a complex vehicle and reception 8
l l
hospital assignment scheme, let alone duplicate the scheme devised by LILCO's consultants.
This could mean that the hospital evacuation time estimates upon which a protective action recommendation would be based could be lengthened.
III.
Findings Q.
Please explain your analysis of how LILCO calculated the longest evacuation time estimate for hospitals.
A.
LILCO's handwritten worksheets calculate evacuation time estimates under seven scenarios.
The scenarios are Schedules 1-6, and "Full 10 Mile."
Schedule 1 corresponds to an evacuation of the fewest EPZ subzones.
Full 10 Mile corresponds to an evacuation of all of the EPZ subzones.
Schedules 2-6 fall in between.
As I indicated above, the longest evacuation time is 12:20, associated with St. Charles Hospital.
Inspection of numerous LILCO worksheets reveals that the longest time occurs under the Full 10 Mile scenario.
A copy of the relevant worksheet is herein.
The third column on the fourth page of the worksheet shows that two ambulances with St. Charles patients crossed the EPZ boundary at 12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br /> after the order to evacuate, which is equivalent to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and 20 minutes.
Following or "tracing," the paths of these two ambulances from the beginning of the emergency to the end is the key to l
i 9
interpreting LILCO's evacuation time estimates.
As demonstrated by Attachment 3 herein, the two ambulances involved in the longest evacuation time (12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br />) participated in two evacuation waves at the Suffolk Infirmary and then participated in a third evacuation wave at St. Charles. herein is the State's computerized version of this trace.
The assignment takes 12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br /> to complete, results in the evacuation of twelve persons, covers 138.52 miles (using LILCO's figures), and consists of eight distinct trips.
In this path, patients are actually transported only during 28% of the time and over 42% of the distance.
The rest of the time is spent traveling to and from the Brentwood staging area, receiving instructions, etc., loading and unloading at hospitals, and waiting in queues at hospitais.
Specifically, the paths or trace of the two key ambulances began when they initially arrived at Brentwood at 2.50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br /> after the order to evacuate.
The two ambulances then traveled to the Suffolk Infirmary, transported patients to the VA Medical Center in Northport, returned to Brentwood, traveled again to the Suffolk Infirmary, again took patients to the VA Medical Center, returned again to Brentwood and then made the trip to St. Charles for the evacuation of the remaining hospital patients.
A copy of the pertinent worksheets, in order of the trace, is Attachment 3 herein.
A diagram of this complex path is shown in Attachment 4 herein.
The worksheets show that, at each step, LILCO makes a series 10
of assumptions about arrival times at staging areas, processing times, highway speeds, travel distances, travel routes, destination hospitals, patient loading and unloading times, and queueing times.
All of these assumptions, as well as others contained in Appendix A of the Plan, are the bases of LILCO's hospital evacuation time estimates.
Q.
Did you also trace the second longest evacuation time estimate for hospitals?
A.
Yes, as I indicated above, the second longest evacuation time is 12.19 hours2.199074e-4 days <br />0.00528 hours <br />3.141534e-5 weeks <br />7.2295e-6 months <br />, associated with Central Suffolk Hospital.
It also occurs under the Full 10 Mile Scenario.
Like St. Charles, the evacuation time for Central Suffolk Hospital is dependent on the time it takes for the vehicles to participate in one prior evacuation wave involving the Suffolk Infirmary.
herein is a diagram that shows the complex movement in the trace of this second longest evacuation time.
Q.
Why is following the traces of the vehicles that provide the longest evacuation times the key to interpreting LILCO's analysis?
A.
The trace of these vehicles is the key because a change in any of the related assumptions could change the time it takes for these last two vehicles to evacuate the last patients.
Thus, we 11
l l
can determine what factors will shorten or lengthen overall evacuation times.
Changes in the assumptions related to evacuation times of other vehicles and patients would not necessarily affect the longest evacuation time, and would therefore not necessarily be the controlling evacuation time estimate.
Tracing the vehicles involved in the longest and second longest evacuation times is also important because it enables the Board to visualize the complexity of the evacuation and the additive nature of the numerous assumptions along the entire trace.
1.
Assumptions Concerning Speeds of Vehicles Q.
Are LILCO's assumptions about speeds of buses, ambulances and ambulettes appropriate?
A.
No.
LILCO's assumptions concerning these speeds are unreliable because they do not account for the uncertainties of future evacuation events.
The assumptions are not compelling in their justification, and are too generous to reflect the congested conditions that the State of New York believes will be likely in an extensive evacuation scenario, as I testified during the reception center proceedings.
See Direct Testimony of David T.
Hartgen and Robert C. Millspaugh on Behalf of the State of New York Regarding LILCO's Reception Centers (April 13, 1987) ("State Reception Center Testimony").
12
1 1
Let us look first at the speeds which LILCO assumes for the Long Island Expressway, one of the main routes traveled by the vehicles which will be evacuating the hospitals.
LILCO lists in Table XIIIB of Appendix A of the Plan a number of assumed speeds, depending on certain factors.
As an example, let us look at the speed for westbound travel on the LIE between the western edge of the EPZ and the village of Brentwood.
LILCO estimates that this speed is 15 miles per hour.
This estimate, however, is unjustified.
During an evacuation, the LIE will be operating under very congested conditions which can be categorized as level of service F1 The Highway Capacity Manual indicates that at level of service F, speeds could vary from 0 mph to 30 mph at any one point in time during such congestion. herein shows the operating curve for speeds versus volume-to-capacity ratio for freeways.
The dotted line at the bottom of the curve shows level of service F.
The average of this portion of the curve is not a fixed number, like LILCO's 15 mph, but rather is a range of speeds dependent on the volume to capacity ratio.
For level of service F congestion, the implied average speed is approximately 8 mph, but the important observation is that speeds are variable between 0 and 30 mph.
Since such a wide 1
The various levels of service and the nature of traffic flow associated with those levels of service were discussed in my testimony on reception centers and will not be repeated here.
See State Reception Center Testimony at 40-46.
l l
13 i
I
range in speed is likely, it is unsound for LILCO to assume an average speed of 15 mph.
At the unstable flow which characterizes level of service F, average travel speed could vary by 5 mph or more.
LILCO should have analyzed the sensitivity of the hospital evacuation time estimates to such a 5 mph variation in assumed average freeway speed.
Q.
What support do you have for your opinion about speeds at level of service F?
A.
An article, co-authored by Mr. Lieberman, one of LILCO's witnesses, supports the State of New York's position.
The article is entitled "Enhanced FREFLO:
Modeling of Congested Environments", by A.K.
- Rathi, E.B.
Lieberman, and M.
- Yedlin, printed in Transportation Research Record No. 1112, Transportation Research Board, Washington, D.C.,
1987.
A copy is herein.
In this article, Mr. Lieberman described a modification of a computer model of freeway traffic flow to make it more realistically reflect congested operation.
He presented results (shown in Table 2 of Attachment 8 herein) showing that in the modified model, "a realistic stop-and-go pattern of entering flow was established." (Attachment 8 herein, at 65).
The article also indicated (Attachment 8 herein, at Table 2) that congested operation implies: (1) traffic densities of 89-152 vehicles per lane-mile, (2) average speeds of 6.9 mph to 10.6 mph, and (3) highly variable vehicle flow rates, ranging from 0 14
to capacity.
Accordingly, Mr. Lieberman's own research bolsters the State of New York's criticism of the assumed speeds set forth in Table XIIIB of Appendix A of the Plan.
Q.
Do you have any concerns about other assumed speeds set forth in Table XIIIB of Appendix A of the LILCO Plan?
A.
Yes.
LILCO produced no data that would justify the assumed speeds in Table XIIIB, especially epteds of vehicles headed away from the EPZ on local streets or non-freeway evacuation routes, and speeds of vehicles headed toward the EPZ.
The assumed speeds appear to be the result of conjecture.
Indeed, Mr. Lieberman stated as much in his deposition.
Liberman Deposition Tr. 23-35 (March 25, 1988).
In particular, the assumption that speeds would be higher between the EPZ and Brentwood than they would be inside the EPZ is without basis because pervasive congestion would reduce speeds in between the EPZ and Brentwood.
In addition, there is no apparent justification for assuming that speeds change at Brentwood.
There is also no support for the assumption in Table XIIIB that ambulances inside the EPZ would travel faster than ambulettes inside the EPZ after the evacuation ends.
This seems illogical because ambulances usually travel faster than other vehicles during periods of congestion, not in the absence of congestion.
15 l
l
1 Further, Table XIIIB contains anomalies which reflect the arbitrary nature of the assumed speeds.
For instance, vehicles are assumed to travel faster on the westbound congested Long Island Expressway (15 mph) than on the northbound uncongested Sunken Meadow Parkway (10 mph).
On Route 111, vehicles are assumed to travel one speed (20 mph) at all times, regardless of congestion and other factors.
Finally, Table XIIIB assumes a remarkable jump in speeds when the evacuation time exceeds the benchmark times listed in Table XIIIB.
Another way of saying this is that the "tail" of the evacuation ends abruptly, meaning that when tPe last general population evacuating vehicles pass a given point, the road suddenly clears.
LILCO has provided no support for this assumption.
Q.
Do you have any other reasons to question the speeds assumed in Table XIIIB?
A.
Yes, as I discussed earlier, LILCO's hospital evacuation time estimates are based on seven scenarios:
Schedules 1-6 and Full 10 Mile. Schedule 1 cor. templates an evacuation of only subzones A-E, I and J.
"Full 10 Mile" contemplates an evacuation of the entire EPZ.
However, the assumed speeds in Table XIIIB are the same regardless of which evacuation scenario actually occurs.
This seems illogi al because more extensive evacuations would presumably generate more evacuating traffic and have a greater tendency to reduce speeds.
It would be more prudent from a 16
t.
planning perspective to assume that more extensive scenarios, such as Schedule 6 and Full 10 Mile, would be characterized by speeds that are lower than speeds in the less extensive scenarios, such as Schedules 1 and 2.
Q.
Have you determined the effect of different speed assumptions on the hospital evacuation time estimates?
A.
- Yes, I recalculated the longest evacuation time estimate (12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br /> for the last two "trace" ambulances to evacuate St.
Charles Hospital) by assuming slightly different speeds than those that LILCO assumed.
I chose these different assumptions to determine a range of answers corresponding to upper and lower bounds of speeds.
The results, which are summarized in herein, reveal the following:
1.
Reducing speeds on the Long Island Expressway to 10 mph outbound, and 25 mph inbound (other roads 15 mph outbound, 20 mph inbound) would increase evacuation times to 14.54 hours6.25e-4 days <br />0.015 hours <br />8.928571e-5 weeks <br />2.0547e-5 months <br />, or 17.3%.
2.
Reducing all speeds by 3-5 mph would increase evacuation times to 14.00 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, or 12.9%.
3.
An across-the-board 10% reduction in speeds would increase evacuation times to 13.07 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />, or 5.4%.

Yes.
I recalculated the longest evacuation time estimate (12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br /> for the last two "trace" ambulances to evacuate St.

4.
Reducing expressway speeds to 6 mph outbound, and 15 mph inbound, would increase evacuation times to 20.58 hours6.712963e-4 days <br />0.0161 hours <br />9.589947e-5 weeks <br />2.2069e-5 months <br />, or 66%.

Allowing operations at present (posted) speeds would decrease evacuation times to 8.97 hours0.00112 days <br />0.0269 hours <br />1.603836e-4 weeks <br />3.69085e-5 months <br />, or -27.6%.
This would appear to be the absolute lower bound for evacuation times.
Calculations for these estimates are in Attachments 10-15 herein.
O.
What is the significance of these results?
A.
It is reasonable to assume that evacuation speeds could be lower than LILCO has postulated.
When such lower speeds are
- assumed, evacuation times for the hospitals could increase to 20.6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, or 66% more than asserted by LILCO.
LILCO should have recognized the inherent uncertainty in its calculations, analyzed the nature and scope of the uncertainty, and put the results in its Plan as guidance to personnel managing the evacuation.

2.
Number of Patients to be Transported Q.
How many hospital patients need to be evacuated, and how many patients are evacuated, according to LILCO's hospital evacuation time estimates?
A. of OPIP 3.6.5, sets forth the number of total beds at each hospital and the handwritten worksheets identify the number of patients at each hospital who were evacuated in connection with the calculations of the hospital evacuation time estimates.
The information is as follows:
Number of Beds Number of Evacuated (Per OPIP 3.6.5, Patients (Per LILCO's Hospital )
Worksheets)
John T. Mather Hospital 238 238 Central Suffolk Hospital 168 168 St. Charles Hospital 271 260 Suffolk Infirmary 215 215 This information is depicted graphically on the bar charts for each hospital in Attachment 16 herein.
Q.
What is the significance of the discrepancy at St. Charles Hospital?
19
d A.
It appears that LILCO's time estimate calculations have neglected to include eleven patients at St. Charlea Hospital.
According to LILCO's origin-destination worksheet (Attachment 17 herein), a total of only 260 patients were evacuated from St.
Charles Hospital, while the number of beds (and the number of patients presumed by LILCO) is 271.
Depending on particular transportation arrangements, inclusion of these omitted patients could result in longer hospital evacuation time estimates.
In any event, an error which could result in patients not being evacuated is significant and casts doubt on the validity of LILCO's calculations.
t i
]
Q.
Do you have any other concerns about the number of patients for whom transportation should be provided?
A.
Yes, LILCO implicitly assumes that the number of patients at the evacuating hospitals in need of tranr.i;ortation will be the same as the current number of beds.
However, no allowance is made for future hospital growth or reductions.
If growth were to 1
occur, evacuation times could become longer.
1 3.
Capability of Reception Hospitals to Receive Patients Q.
Have you analyzed the capability of the reception hospitals to receive patients?
4 2
20
A.
Yes.
First of all, I discovered two serious errors in the worksheets that were used by LILCO's consultants to prepare the hospital evacuation time estimates.
One. error, as seen in the attached worksheet (Attachment 17 herein) is that LILCO assigned 30 evacuating patients to a reception hospital named Lydia Hall.
This hospital is closed and is not included within the list of potential reception hospitals in Attachment 5 of OPIP 3.6.5.
Of these 30 patients, 16 are from St. Charles Hospital.
The assignment of evacuating patients to a hospital that is not available and not even contemplated in LILCO's plan renders LILCO's evacuation time estimates incomplete.
Another error, as seen in the attached worksheet (Attachment 17 herein) is that LILCO assigned evacuating patients to Massapequa Hospital, which also is not on the list in Attachment 5 of OPIP 3.6.5.
This affects 14 patients assigned from St.
Charles Hospital.
Again, this error jeopardizes LILCO's results.
Both errors demonstrate that LICLO's evacuation time estimates do not reflect what might acutally occur in a real emergency.
In accordance with Section 5.5.5 of OPIP 3.6.5, LILCO's Hospital Coordinator would not assign any evacuating patients to either one of these hospitals, and, therefore, would not duplicate the "evacuation strategy" that LILCO's consultants used in the calculation of the time estimates, and would not be able to f
effect an evacuation within the time frame anticipated by i
LILCO's hospital evacuation time estimates.
21 i
I These errors are particularly serious because they involve St. Charles patients, who have the longest evacuation times.
In reality, those patients would have to be transferred elsewhere, which could further increase evacuation times.
Q.
Are there any other errors concerning the assignment of patients to hospitals?
A.
Yes.
Section 5.5.5 cf OPIP 3.6.5 instructs the Hospital Coordinator to assign evacuating patients requiring ambulances to the closest reception hospital.
For Central Suffolk Hospital, one of the closest hospitals would be Eastern Long Island Hospital in Greenport, which is on the list of possible reception hospitals in Attachment 5 of OPIP 3.6.5.
See Attachment 16 herein.
However, the worksheets prepared by LILCO's consultants indicate that no patients were assigned to Eastern Long Island Hospital.
Similarly, Syosset Hospital, which also is on the list of possible reception hospitals in Attachment 5 of OPIP 3.6.5, is not used even though it is closer to the EPZ than several hospitals that were used.
Such assignments may or may not have an effect on evacuation times, but the point is that the Hospital Coordinator would implement a different "evacuation strategy," assuming that he or she followed OPIP 3.6.5, Section 5.5.5, than that which was implemented in the calculations that generated the hospital evacuation time estimates.
Therefore, there is no assurance that the actual evacuation time would 22
coincide with what LILCO's emergency planners think the time will be when they rely on the time estimates to make what the Board referred to as "fundamental decisions of health and safety for the 2 1tients in the hospitals."
In addition, according to Sections 5.5.5 and 5.6.1 of OPIP 3.6.5, vehicles not expected to be needed for additional trips are assigned to reception hospitals farthest away from the EPZ.
However, it is likely that LILCO's personnel would not know the extent of the final evacuation until the accident itself progressed to its terminal stages.
In other words, LILCO's personnel would not know if the Schedule 1 evacuation under which they were proceeding might develop into a Full 10 Mile evacuation or might not develop beyond a Schedule 1 evacuation at all.
For example, LILCO's worksheets indicate that the trace vehicles are assigned to transport patients from the Suffolk Infirmary to St.
John's Hospital under a Schedule 6 evacuation.
However, under a Full 10 Mile evacuation, LILCO's worksheets indicate that the same trace vehicles are assigned to transport patients from the Suffolk Infirmary to the VA Medical Center.
This means that LILCO's personnel must know whether the evacuation will terminate as a Schedule 6 evacuation or as a Full 10 Mile evacuation before they assign the vehicles to reception hospitals.
Obviously, if the accident does eventually progress to a Full 10 Mile evacuation, the vehicles might have to change destinations to l
adhere to the Full 10 Mile assignment, and longer evacuation times than those that were anticipated in LILCO's worksheets 23
'l l
might result.
Q.
Does the LILCO Plan contemplate filling reception hospitals to capacity?
A.
Generally, yes.
Q.
Could this policy result in increased evacuation times?
A.
Yes.
Assuming that reception hospitals have a 14% vacancy rate, I have prepared Attachments 16 and 18 herein, which show the reception hospitals and their available capacities, along with the number of patients assigned to them from each evacuating hospital. 6 herein clearly illustrates that virtually all of the available capacity in tne 10 nearest hospitals west of the EPZ is used up.
Essentially, the LILCO Plan is right at the margin of capacity for all of the proximate reception hospitals.
A slight increase in patients to be transported out of the EPZ, or a reduction in reception center capacity (perhaps due to an influx of arriving general population evacuees), could cause an increase in evacuation time.
A prudent assessment woulo have included a test of the sensitivity of the evacuation time estimates to assumptions about capacity of reception hospitals, because so much of the available capacity is taken up.
For example, I calculated the additional time it would take for the ambulances involved in the longest 24
evacuation time at St. Charles Hospital ('.he "trace") to transport patients to Huntington Hospital if the VA Medical Center ('che reception hospital used by LILCO's consultants in the worksheets) were already filled to capacity.
(The VA Medical Center might already be filled for several reasons, including something as simple as the Hospital Coordinator assigning other vehicles to go there beforehand, which is the Hospital Coordinator's prerogative under OPIP 3.6.5.) 9 herein shows that if just the second wave (i.e.,
the second trip from Suffolk Infirmary to the reception hospital) must travel to I
Huntington Hospital instead of the VA Medical Center, assuming LILCO's travel speeds, the overall hospital evacuation time estimate for the trace vehicles is increased by 19 minutes to 12.72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Although a 19 minute increase may not seem substantial, it could be significant due to the additive nature of LILCO's many assumptions.
This is just a sample of the kind of sensitivity analysis that LILCO should have performed but neglected to perform.
4.
Vehicle and Vehicle Driver Availability Q.
Have you reviewed LILCO's hospital evacuation time estimates from the perspective of vehicle availability?
A.
Yes.
LILCO assumes that 63 ambulances and 130 ambulettes will be available to evacuate persons in special facilities and 25
persons who are homebound.
If any of these vehicles are not available, then the slack will have to be taken up by more waves of departures for those vehicles that are available.
The effect could be lengthened evacuation times.
As a rule of thumb, bus companies. typically build in an approximate 15% fleet excess to ensure continued full operation.
This allows for periodic maintenance or other events that reduce fleet presence.
This means that if LILCO needs 193 ambulances and ambulettes to implement the evacuation, LILCO should plan to have a 15% surplus on hand.
By inference, LILCO's current fleet size of 193 ambulances and ambulettes should be discounted by 151 to account for the lack of a 15t surplus.
In other words, LILCO's hospital evacuation time estimates involve 193 ambulances and ambulettes.
To ensure that 193 actually would be available, LILCO should have 193 +.15(193), or 222 ambulances and ambulettes, at the Brentwood and Peconic staging areas.
With 193 ambulances and ambulettes, LILCO only ensures that it has 193 -
.15(193), or 164, ambulances and ambulettes.
Evacuation times would be lengthened if LILCO only has the number of evacuation vehicles actually available in an emergency.
Other reasons why ambulances and ambulettes might not be available are:
1.
The special health facilities, which evacuate with their own vehicles, t ald reduce their fleet size through lack of replacement, of aging vehicles or other reasons, putting more of a burden on LILCO's fleet; 26
2.
The special facilities populations might grow much faster than growth, if any, in LILCO's fleet; U
3.
Ambulance companies may be called directly by private. citizens, thereby reducing the number of vehicles available to LILCO a. 3rentwood or Peconic.
Furthermore, LILCO assumes that vehicles will arrive in accordance with the arrival distribution specified in the contracts.
This general distribution is then arbitrarily broken down into finer 10-minute arrivals, for purposes of dispatching.
There appears to be no empirical basis for this arrival-every,
minute distribution, but it appears that if a critical ("trace")
ambulance were to arrive one hour late, then the evacuation times would be lengthened by approximately an hour.
The ratio between arrival tardiness and evacuation duration is 1 to 1.
Q.
Have you reviewed LILCO's hospital evacuation time estimates from the perspective of vehicle driver availability?
A.
Yes. LILCO implicitly assumes that each vehicle has one driver for the full time period necessary.
This is unrealistic because leave time, fatigue and work rules, etc. may reduce tne number of available drivers.
27
Consistent with what has been previously discussed regarding planned vehicle excesses, bus companies typically employ 1.35 to 2.0 times as many drivers as vehicles to ensure that a fleet of a given size can in fact be operated. 0 herein presents more precise figures in this regard. LILCO should have followed the same principle and planned for a 35% - 100% surplus instead of planning for 0% surplus.
Driver unavailability due to fatigue could result in lengthened evacuation times.
5.
Hospital Evacuation Routes Q.
What assessment have you made concerning routes used in the evacuation of hospitals?
A.
The LILCO Plan does not expressly describe the routes used in the evacuation of hospitals.
There is a general assumption 1
stated that the routes taken are assumed to be those used by the general evacuation population, but since many of the reception hospitals are not on those routes, clearly some off-path travel is implied.
The worksheets, however, describe the individual routes assumed for each movement.
I did not check all of the routes because there were too many, but I did focus on the path of the trace vehicles.
These paths, for the two longest traces, are shown in Attachments 4 and 6 herein.
Q.
What concerns do you have about the routes to be taken?
28 l
l l
t i
l A.
I have the following concerns:
1.
The routes are not minimum time paths.
Although the routes were selected to "minimize delays," the main selection criteria were that "major routes" or "more prominant, more familiar roads" were preferable and "local streets" or "circuitous routes" were avoided.
Lieberman Deposition Tr. 66-67 (March 25, 1988); Sobotka Deposition Tr. 23 (March 7, 1988).
In short, the selection criteria were qualitative, not quantitative.
Essentially, the routes were selected arbitrarily.
2.
Route distances appear to be in error.
Many route lengths were estimated by scaling the distances off Hagstrom maps, and multiplying by a scaling factor.
To correct these problems, I carefully reviewed the distances on the trace path to assess this method.
Of the 11 primary distances, two were correct.
All of the segments on the State routes were, in fact, of different i
lengths, and arithmetic and scaling errors were made on the remainder of the segments.
Some of these resulted in longer or shorter distances. 1 herein I
shows the results.
When the trace is corrected for these 1
errors, a +1.52-mile difference is introduced:
The revised trace time is 12.40 (12:24).
See Attachment 22 herein.

4 3.
Several route directions could be confusing to drivers.
On the route to St. Charles Hospital, vehicles are assumed to travel north on Route 25A to Port Jefferson, and then to take a right on Myrtle Avenue. -
However, a generic hospital roadsign (intended to direct motorists to Mather Hospital) is posted four intersections earlier, at North Country Road.
There is no direction sign for St. Charles Hospital at the Myrtle Avenue turn.
Drivers destined for St. Charles Hospital could depart from the assumed route and report to Mather Hospital by mistake.
This could delay the St. Charles evacuation, particularly if queues form at Mather.
These are problems on the longest path.
It is reasonable to assume that other paths have similar problems.
6.
Formation of Queues at Evacuating and Reception Hospitals O.
What concerns do you have about the formation of queues at hospitals?
30
A.
LILCO's implicit assumption appears to be that vehicles were dispatched so as to minimize queue formation.
Sobotka Deposition Tr. 71 (March 7, 1988).
However, that goal was not achieved, since this is not an optimizing model in any sense and the trace path does, in fact, contain queueing time totaling 18 minutes.
For summer adverse conditions, the queuing time is 1.62 hours7.175926e-4 days <br />0.0172 hours <br />1.025132e-4 weeks <br />2.3591e-5 months <br />, or 10% of the total time.
Also, documentation on how the queues were calculated is non-existent beyond approximately six hours.
The bases of these calculations are unknown.
Since queues are clearly a result of inefficient dispatching, it would seem that LILCO should improve its dispatching procedures to reduce them.
7.
LILCO's Effort Has Not Been Comprehensive Q.
On the subject of hospital evacuation time estimates, is the j
LILCO Plan sufficiently comprehensive?
i A.
The portion of the LILCO Plan that deals with hospital evacuation time estimates is not a "plan" at all, but a set of largely arbitrary and unsupported assumptions supplemented by worksheets that produce a single "answer,"
i.e.,
the longest evacuation time estimate of 12.34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br />.

4.

5.
Actions to ensure that the recommended procedure can, in fact, be implemented effectively, and actions to respond to unforeseen circumstances.
8.
Failure to Use Appropriate Analytical Tools Q.
Did LILCO use appropriate analytical tools to generate its hospital evacuation time estimates?
32
A.
LILCO did not use a number of analytical tools which, if used, would likely have lead to more reliable hospital evacuation time estimates.
For instance, the time-based routing should have been handled with a computerized network of the evacuation area between the EPZ and the reception centers.
Alternative origin-destination assignments could then have been efficiently selected.
The scheduling could have been undertaken with either l
an integer programming algorithm, or with a dynamic simulation model, so that the true optimum assignment could be determined.
Finally, once identified, the best schedule should have been converted to specific instructions to the LILCO Coordinators on how to im{lsment it.
i IV.
Summary Q.
Please summarize your findings concerning the bases and accuracy of LILCO's hospital evacuation time estimates?
A.
The need for information about variables affecting evacuation times is substantial because LILCO's hospital evacuation time estimates are based on assumptions, many of which are subject to wide variations, and some of which are not well-supported. For example, the longest evacuation time (12:20) is derived from two ambulances which participate in two evacuation waves involving the Suffolk Infirmary, and then participate in another evacuation 33
wave involving St. Charles Hospital.
Every step in this sequence of eight trips is based on assumptions about arrival times at staging areas, processing times, highway speeds, distances, travel routes, destination hospitals, patient loading and unloading times, and queuing times that are at best questionable or unsupported, at worst miscalculated.
Without a full sensitivity analysis assessing the affect of variations in these assumptions, the LILCO Plan is incomplete.
LILCO, however, ignores the need for more information about variables and unrealistically assumes that all of its assumptions will in fact hold true in a real emergency.
The most critical assumptions made by LILCO concern speeds.
Given that congestion will be pervasive and that level of service F operation will be the rule, speeds cannot be determined to any greater accuracy than 5 mph.
However, LILCO failed to consider this variation in speed.
As can be seen from Attachment 9 herein, more realistic assumptions involving speed variations, when applied to the LILCO trace vehicles, yield an evacuation time of 14.5 - 20.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, or 17-66% more than LILCO's numbers.
This is just one illustration of how evacuation times are increased by applying a different, more appropriate set of 1
assumptions.
Errors concerning the number of patients to be evacuated, road distances, and reception hospital assignments also reveal inaccuracies that belie LILCO's time estimates.
Furthermore, factors such as vehicle and vehicle driver availability, hospital evacuation routes, and formation of queues i
34
at hospitals bear upon LILCO's time estimates.
Taken together, all of these considerations have the additive effect of substantially increasing LILCO's hospital evacuation time estimates.-
Q.
Are LILCO's hospital evacuation time estimates reliable?
A.
No, for the reasons stated above.
Q.
Does this conclude your testimony?
A.
Yes.
