Current through all regulations passed and filed through September 3, 2021

(B) Where methods and procedures are not specified by other applicable rules and laws or an NPDES permit, a water quality credit shall be calculated as follows:
(1) Unless alternate methods are deemed acceptable by the director, be calculated using the load reduction spreadsheet used to estimate load reductions that are achieved by implementing BMPs; or .
(2) For pollutants or BMPs not included in the load reduction spreadsheet, be calculated using generally accepted engineering methods deemed acceptable by the director.
(C) When evaluating load reductions for any water quality credit, the director may consider monitoring data for pollutant load reductions resulting from the implementation of BMPs or changes in land use.
