USFK Regulation 201-1 OWS Effluent.pdf

USFK REG 201-1, 30 July 2020 or vapors.

(e) Waste capable of detonation or explosive decomposition or reaction at standard temperature and pressure.

(f) Wastes that contain explosives regulated by Chapter 5, “Hazardous Material.”

(g) Wastes which produce any toxic fumes, vapors, or gases with the potential to cause safety problems or harm to workers.

(4) Corrosivity. It is prohibited to discharge pollutants that have the potential to be structurally corrosive to the DWTS. Specifically, no discharge of wastewater below a pH of 5.0 or above a pH of 9.0 is allowed, unless the DWTS is specifically designed to handle that type of wastewater.

(5) Oil and grease. The direct discharge of the following oils, which can pass through or cause interference to the DWTS, is prohibited: petroleum oil, non-biodegradable cutting oil, and products of mineral oil origin.

(6) Spills and batch discharges (slugs). Activities or installations that have a significant potential for spills or batch discharges will develop a slug prevention plan. Each plan must contain the following minimum requirements:

(a) Description of discharge practices, including non-routine batch discharges.

(b) Description of stored chemicals.

(c) Plan for immediately notifying the DWTS of slug discharges and discharges that would violate prohibitions under this chapter, including procedures for subsequent written notification within five days.

(d) Necessary practices to prevent accidental spills. This would include proper inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, and worker training.

(e) Proper procedures for building containment structures or equipment.

(f) Necessary measures to control toxic organic pollutants and solvents.

(g) Proper procedures and equipment for emergency response, and any subsequent plans necessary to limit damage suffered by the treatment plant or the environment.

(7) Trucked and hauled waste. The discharge of trucked and hauled waste into the DWTS, except at locations and under conditions specified by the DWTS operator, is prohibited.

(8) Heat in amounts that inhibit biological activity in the DWTS resulting in interference, but in no case in such quantities that the temperature of the process water at the DWTS exceeds 40°C (104°F).

f. Effluent limitations for specific industrial dischargers. In addition to requirements in paragraph 4-3e, industrial wastewater sources listed in table 4-6 must comply with discharge requirements identified in table 4-7. Effluent limitations for electroplating.
