Whenever inspection and/or monitoring reveals that the BMPs identified in the Construction SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant. appropriate BMPs or design changes shall be implemented as soon as possible. Maintaining an Updated Construction SWPPP. The construction SWPPP shall be retained on -site or within reasonable access to the site The SWPPP shall be modified whenever there is a change in the design, construction, operation, or maintenance at the con, .ruction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state.
