the environment caused by the activities of the permittee in the conduct of its actions, including those activities authorized,
directed, or undertaken under the permit. To the extent the state and Agency may be liable for the activities of its

level of pollutant reductions that an owner or operator of regulated MS4s must achieve. The USEPA has intentionally not
provided a precise definition of MEP to allow maximum flexibility in MS4 permitting. The pollutant reductions that
represent MEP may be different for each small MS4, given the unique local hydrologic and geologic concerns that may exist
and the differing possible pollutantcontrol strategies. Therefore, each permittee will determine appropriate BMPs to
satisfy each of the six Minimum Control Measures (MCMs) through an evaluative process. The USEPA envisions application
of the MEP standard as an iterative process. \[Minn. R. 7090\]

Community Right-to-Know Act (EPCRA); fertilizers, pesticides, and waste products such as ashes, slag, and sludge that have
the potential to be released with stormwater discharges. When determining whether a material is significant, the physical
and chemical characteristics of the material should be considered (e.g. the material's solubility, transportability, and toxicity
characteristics) to determine the material's pollution potential. \[40 CFR 122.26(b)(12)\]
27.34"Small Municipal Separate Storm Sewer System" or "small MS4", means all separate storm sewers that are:

allocations for nonpoint sources and natural background, as more fully defined in 40 CFR 130.2, paragraph (i). A TMDL sets
