Phase II MS4s are not required to conduct water quality monitoring, how can I ensure our SWMP is focused on the right environmental concerns without having to collect samples?
Although sampling is not required, several other methods may be used to focus BMP efforts. Review of Regional Water Quality Control Plans (Basin Plans) can reveal existing water quality problems in your area. Receiving water monitoring data from other entities or listing of impairment on the 303(d) list of impaired water bodies can also identify water quality problems. For indications of the quality of your discharge, you can review studies such as the National Urban Runoff Program (NURP) that have characterized runoff from different land uses or monitoring data from Phase I communities.
