NOTES:
| ||
All units in mg/l, unless otherwise specified. The daily maximum
limits are based on a composite sample for the twenty-four-hour or
working-hour period as approved by the Town, except for pH, oil and
grease, cyanide, and volatile organics. The Town will define the sample
collection and sample type of each pollutant for compliance assessment.
| ||
(1)
|
Dischargers exceeding BOD5, TSS, ammonia and/or phosphorus limitations as stated above may request a variance from the Town. Based upon the submitted supporting concentration and loading data and the available treatment plant loadings, the Town may allow discharge of wastewater with the concentration(s) greater than the limits imposed above, upon payment of a sewer surcharge fee, as set forth further in § 228-12E and § 100-19U, based upon availability of any excess capacity available at the treatment plant. The Town reserves its right to impose an upper cutoff concentration limit based upon available treatment plant capacity and loadings.
| |
(2)
|
The Town may impose discharge limitations, restrictions, and/or
prohibition of total toxic organics (TTO), including any volatile
organics, base/neutral organics, acid extractable organics, pesticides,
PCBs and any other toxic organic, on a case-by-case basis.
