<br />The General Permit incorporates by reference the applicable portions of 40 CFR 122.41 and 122.42(c) and (d), and
<br />Minn. R. 7001.1090, which are enforceable parts of the General Permit. [Minn. R. 7090]
<br />26.17
<br />The provisions of the General Permit are severable, and if any provision of the General Permit, or the application of
<br />any provision of the General Permit to any circumstance, is held invalid, the application of such provision to other
<br />circumstances and the remainder of the General Permit shall not be affected thereby. [Minn. R. 7090]
<br />27.1
<br />Definitions. [Minn. R. 7090]
<br />27.2
<br />"Active karst" means a terrain having distinctive landforms and hydrology created primarily from the dissolution of soluble
<br />rocks within 50 feet of the land surface. [Minn. R. 7090]
<br />27.3
<br />"Agency" means the Minnesota Pollution Control Agency or MPCA. [Minn. Stat. 116.36, subd. 2]
<br />27.4
<br />"Alum or Ferric Chloride Phosphorus Treatment System" means the diversion of flowing stormwater from a MS4, removal
<br />of phosphorus through the use a continuous feed of alum or ferric chloride additive, flocculation, and the return of the
<br />treated stormwater back into a MS4 or receiving water. [Minn. R. 7090]
<br />27.5
<br />"Applicable WLA" means a Waste Load Allocation assigned to the permittee and approved by the USEPA prior to the
<br />issuance date of the General Permit. [Minn. R. 7090]
<br />27.6
<br />"Best Management Practices" or "BMPs" means practices to prevent or reduce the pollution of the waters of the state,
<br />including schedules of activities, prohibitions of practices, and other management practices, and also includes treatment
<br />requirements, operating procedures and practices to control plant site runoff, spillage or leaks, sludge, or waste disposal or
<br />drainage from raw material storage. [Minn. R. 7001.1020, subp. 5]
<br />27.7
<br />"Commissioner" means the Commissioner of the Minnesota Pollution Control Agency or the Commissioner's designee.
<br />[Minn. Stat. 116.36, subd. 3]
<br />27.8
<br />"Common Plan of Development or Sale" means a contiguous area where multiple separate and distinct land disturbing
<br />activities may be taking place at different times, on different schedules, but under one proposed plan. One plan is broadly
<br />defined to include design, permit application, advertisement or physical demarcation indicating that land -disturbing
<br />activities may occur. [Minn. R. 7090]
<br />27.9
<br />"Construction Activity" means activities including clearing, grading, and excavating, that result in land disturbance of equal
<br />to or greater than one acre, including the disturbance of less than one acre of total land area that is part of a larger
<br />common plan of development or sale if the larger common plan will ultimately disturb equal to or greater than one acre.
<br />This includes a disturbance to the land that results in a change in the topography, existing soil cover, both vegetative and
<br />nonvegetative, or the existing soil topography that may result in accelerated stormwater runoff that may lead to soil
<br />erosion and movement of sediment. Construction activity does not include a disturbance to the land of less than five acres
<br />for the purpose of routine maintenance performed to maintain the original line and grade, hydraulic capacity, and original
<br />purpose of the facility. Routine maintenance does not include activities such as repairs, replacement and other types of
<br />non -routine maintenance. Pavement rehabilitation that does not disturb the underlying soils (e.g., mill and overlay
<br />projects) is not construction activity. [Minn. R. 7090]
<br />27.10
<br />"DNR Catchment Area" means the Hydrologic Unit 08 areas delineated and digitized by the Minnesota DNR. The catchment
<br />areas are available for download at the Minnesota DNR Geospatial Commons website. DNR catchment areas may be locally
<br />corrected, in which case the local corrections may be used. [Minn. R. 7090]
<br />27.11
<br />"Existing Permittee" means an owner/operator of a small MS4 that has been authorized to discharge stormwater under a
<br />previously issued general permit for small MS4s in the state of Minnesota. [Minn. R. 7090]
<br />27.12
<br />"Fully reconstructed" means areas where impervious surfaces have been removed down to the underlying soils. Activities
<br />such as structure renovation, mill and overlay projects, and other pavement rehabilitation projects that do not expose the
<br />underlying soils beneath the structure, pavement, or activity are not considered fully reconstructed. Maintenance activities
<br />such as catch basin repair/replacement, utility repair/replacement, pipe repair/replacement, lighting, and pedestrian ramp
<br />improvements are not considered fully reconstructed. [Minn. R. 7090]
<br />27.13
<br />"General permit" means a permit issued under Minn. R. 7001.0210 to a category of permittees whose operations,
<br />emissions, activities, discharges, or facilities are the same or substantially similar. [Minn. R. 7001.0010, subp. 4]
<br />27.14
<br />"Geographic Coordinates" means the point location of a stormwater feature expressed by X, Y coordinates of a standard
<br />Cartesian coordinate system (i.e. latitude/longitude) that can be readily converted to Universal Transverse Mercator (UTM),
<br />Zone 15N in the NAD83 datum. For polygon features, the geographic coordinates will typically define the approximate
