Rc = 0.00834 p (C – 300)
|
Where:
| |||
Rc
|
=
|
the BOD surcharge rate in cents per 1,000 gallons of waste discharged.
| |
p
|
=
|
the average annual fixed, operating and maintenance cost of
secondary treatment processes per pound of BOD received at the treatment
works. Such secondary processes shall include chlorination as well
as trickling filter or activated sludge processes. (Prior to completion
of the first year of operation, the value of "p" shall be assumed
to be $0.04.)
| |
C
|
=
|
the average BOD of the industrial waste expressed in parts per million as determined in accordance with § 371-73 of this article.
|
R2 = 0.00834 × B (S – 275)
|
Where:
| |||
R2
|
=
|
the suspended solids surcharge rate in cents per 1,000 gallons
of waste discharged.
| |
B
|
=
|
the average annual fixed, operating and maintenance cost of
the sludge digestion, sludge drying and sludge disposal operations
per pound of suspended solids received at the treatment works. (Prior
to completion of the first year of operation, the value of "B" shall
be assumed to be $0.04.)
| |
S
|
=
|
the average suspended solids concentration of the abnormal industrial waste expressed in parts per million as determined in accordance with § 371-73 of this article.
