4 This testimony was developed in response to the Joint Interveners (JI) Contention 57 regarding the process for handling and disposal of contaminated waste water and contaminated materials as described in the Seabrook Plan for Massachusetts Communities (SPMC).
I.
SOLID WASTE HANDLING / DISPOSAL During the activation and set-up of the Monitoring Trailers and emergency worker facility, the Monitoring / Decontamination Leaders assign personnel to various tasks including decontamination activities (SPMC, IP 2.9 at steps 5.2.9 and 5.3.7).
Specifically, two Monitoring / Decontamination personnel are assigned to decontamination activities inside the Monitoring Trailers (e.g., decontamination of persons and small articles) and four are assigned to decontamination activities outside the trailers (e.g.,
decontamination of vehicles, personal articles and equipment).
These personnel are responsible for ensuring that contaminated personal articles and contaminated waste are placed in the proper, clearly identifiable yellow plastic bags.
Thus, contrary to the assertion made by the Joint Interveners, personnel to bag, label and set aside contaminated materials are designated in the SPMC.
The contaminated solid wastes would include paper, wipes, muslin cloth, sponges, tewels and other supplies used i
during the decontamination activities at the trailers.
Waste bags that have been filled during the emergency phase of an - _ _ _ _ _ - _
accident are securely sealed and placed in a controlled area designated.by the Monitoring / Decontamination Leader for disposal at a later time. 'The controlled area also includes space for the storage of contaminated personal articles which will be decontaminated and returned to the owners.
The boundaries of the controlled area are identified by either yellow and magenta rope, or tape with the word
" radioactive" printed at intervals.
Since there is no basis to expect general public evacuees to violate the controlled area, only one Monitoring / Decontamination person is assigned to watch over the contaminated articles.
During the emergency phase, Monitoring /
Decontamination personnel are primarily concerned with meeting the monitoring and decontamination needs of evacuees.
The number of personnel assigned to decontamination activities is adequate for the handling of contaminated wastes generated during this phase, because the waste is tagged and set aside in a controlled area.
Once the emergency phase of an accident ends, personnel who were assigned initially to other duties can be reassigned to handle contaminated waste (SPMC,.IP 2.9, step 5.2.2.1).
The Monitoring / Decontamination Leader contacts the Radiological Health Advisor at the New Hanpshire Yankee (NHY)
Offsite Response Emergency Operations Center (EOC) for licensed disposal of contaminated waste material as part of the deactivation of the trailer (SPMC, IP 3.3 at step 5.1.15 I
l and IP 3.4 at step 5.1.17).
The Radiological Health Advisor, as part of recovery operations, will coordinate the disposal of radiological waste through Seabrook Station Emergency Response Organization (ERO).
l Radiological waste disposal will be accomplished through a contractual agreement between Chem-Nuclear Systems, Inc.
and New Hampshire Yankee which will be in place prior to commercial operation.
The terms of the contract cover radiological waste generated during the implementation of the SPMC.
A letter confirming the contract agreement is provided as Attachment A hereto.
The Chem-Nuclear personnel who respond during an emergency for purposes of waste disposal will use that firm's processing procedures, which are consistent with applicable federal requirements for packaging and transport of contaminated wastes.
II.
WASTE WATER AT THE MONITORING TRAILERS Waste water generated from decontamination activities at the Monitoring Trailers at the Reception Centers will be j
stored until processing and licensed disposal can be performed.
Disposal of waste water will be accomplished i
through a contractual agreement between Chem-Nuclear Systems, Inc. and New Hampshire Yankee.
The terms of the contract cover waste water generated during the implementation of the i
SPMC. l 1

A.
Anticipated Production of Waste Water The flow rates for the showers at each Monitoring Trailer were evaluated.
The highest observed flow rate was 2.11 gallons per minute (gpm), which occurred at the Beverly Monitoring Trailer when only one shower was running.
This flow rate was selected to conservatively estimate waste water production at each Monitoring Trailer.
Each shower stall is configured with an adjacent changing area.
The planning basis for this configuration allows for one shower to take approximately ten minutes (i.e., a five minute shower and a five minute changing time).
Accordingly, each shower will produce waste water for five minutes per ten minute shower.
Under constant operation, each shower will produce waste water for thirty minutes of each hour.
Using the maximum flow rate value and assuming constant operation of both showers, the waste water production rate is calculated for the trailers:
(2 showers / trailer) x (2.11 gpm/ shower) (30 running minutes / hour) = 126.6 gallon / hour per trailer l

Waste Water Storage and Processing Chem-Nuclear Systems, Inc. requires 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to respond to an emergency at Seabrook Station.
(Oct. 13, 1988 letter from Chem-Nuclear to New Hampshire Yankee, Attachment B hereto).
Therefore, each trailer needs the capacity to store any
- d all waste water generated at the facility for approximately the first 24-hour period of shower operation.
The maximum amount of waste water generated during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at each trailer is 126.6 gallon / hour x 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> =
3038.4 gallons.
Each trailer is currently equipped with four waste water tanks that provide a total storage capacity of 1200 gallons.
To supplement these tanks, additional storage capacity for at least 2300 gallons will be made available at each trailer site.
This will effectively increase the water storage capacity of each trailer to at least 3500 gallons, which includes an approximate 13 percent surplus capacity.
Once Chem-Nuclear's services are available, waste water can be processed in an expeditious manner and represent a practically limitless cycle of waste water handling and disposal capacity.
