§ 88.297. Hydrologic balance: treatment facilities.

(a)  At a minimum, facilities and measures for treating discharges from disturbed areas shall be designed, constructed and maintained to treat the runoff from a 10-year, 24-hour precipitation event and any groundwater contribution.
(b)  Facilities and measures for treating any discharges shall be based on good engineering design and shall include automatic neutralization processes. The Department may approve a manual neutralization system if the Department finds that:
   (1)  Flow is infrequent and presents small and infrequent treatment requirements to meet the applicable effluent limitations.
   (2)  Timely and consistent treatment is ensured.
(c)  The design, construction and maintenance of a treatment facility shall not relieve an operator of his responsibility for complying with the applicable treatment requirements and effluent limitations of § 88.292 (relating to hydrologic balance: effluent standards).
