(A) Any discharger using bulk salt (greater than 100 pounds per day) for product preparation and/or ancillary plant operations (such as water softeners for boilers) or other chemicals that contribute salinity to the discharge, shall implement and submit to the General Manager a salinity control plan by the effective date of this chapter. The salinity control plan shall use best management practices to reduce the electrical conductivity discharges below the maximum concentration limitation provided in § 7.20.480. The salinity control plan shall contain the following items, at a minimum:
(1) Determinations or best estimates of the identities and approximate quantities of salts used and discharged;
(2) Descriptions of the major salting operations and locations of potential salt release points on site drawing;
(3) A spill prevention, control and countermeasures (SPCC) plan;
(4) A description of the methods of salt waste removal and disposal;
(5) A description of the employee training program for salinity control; and
(6) Identification of the person responsible for implementation of the salinity control plan.
(B) The salinity control plan shall be implemented and submitted to the General Manager by the effective date of this chapter and endorsed by industry officials.
(C) The salinity control plan shall be updated by the discharger during renewal of the wastewater discharge permit.
(D) In the case of any accidental slug or batch discharge of salt wastes that causes the discharger’s wastewater electrical conductivity to exceed the maximum concentration limitation provided in § 7.20.480, the discharger shall immediately notify the General Manager days of such discharge and submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the discharger to prevent similar future occurrences.
