1BOD is Ultimate Biochemical Oxygen Demand. Its concentration is derived by the following: BOD5 /0.80+ 4.5(TKN)=(UBOD). NOTE: The amount of TKN utilized depends on the location in the basin.
2Projected for 1977 based on population projections.
3Recommended allocation based on BPCTCA effluent guidelines applied to raw waste loads at 2020.
4Minimum removal efficiency.
5Allocation based on BPCTCA effluent guidelines; amended by Minute 25, June 3-5, 1979 board meeting.
7Assimilative capacity.
8Amended by Minute 1, August 17, 1978, board meeting.

NOTES: (1) Parham Landing WWTP: waste load allocations
(WLAs) based on a design flow capacity of 3.0 2.0 million gallons
per day (MGD). If plant is not certified to operate at 3.0 2.0
MGD design flow capacity by December 31, 2010, the WLAs will decrease to TN =
10,416 lbs/yr; TP = 1,215 lbs/yr, based on a design flow capacity of 0.57 MGD.
