MEMORANDUM
TO: File
FROM: J. Trevor Clements
SUBJECT: Salisbury Grants Creek WWTP
After conferring with Meg Kerr (Tech. Supp. Supervisor) and Alan
Wahab of Construction Grants, it was decided that the BOD5 and NH3-N
limits formerly developed for Salisbury would be applied as final permit
recommendations. These limits were determined using the old ultimate BOD
breakdown of: 1.0 BOD5 + 4.0 NH3'-NIt has now come to our attention
that Salisbury receives industrial waste comprising about 20 percent of
their wasteflow. If this new information were incorporated with the
development of limits, Salisbury's limits would be substantially more.
stringent (2.0 BOD5 + 4.57 NH3-N). For Salisbury's allocation of 39
mg/1 ultimate BOD, the alternative breakdowns are shown below:
a) 1.0 (15 mg/1 BOD5) + 4.0 (6 mg/1 NH3-N) = 39 mg/1 BODult
b) 2.0 (10 mg/1 BOD5) + 4.57 (4 mg/1 NH3-N) = 39 mg/1 BODult
Several elements of the 201 area plan for Salisbury were based upon the
limits shown above in (a.). Because of these plans and commitments, the
current permit limitations will reflect those numbers. However, future
permits should reflect the new information and Salisbury should be made
aware of the potential for change.
