A. Required Information: The storm water pollution prevention plan (the "plan") shall contain the following information:
1. Site Description: A site description (including a map with spot elevations and contour lines) which includes a description of the nature and location of the construction activity, a description of the intended sequence of major activities which will disturb soils for major portions of the site (e.g., grubbing, excavation, grading, utilities, and infrastructure installation, etc.), and estimates of the total area of the site and the total area of the site that is expected to be disturbed by excavation, grading, or other activities;
2. Control Description: A description of the proposed measures and controls that will be implemented during construction activity and/or while the site is not stable. The plan must clearly describe the times during the construction process that the measures will be implemented for each major activity identified pursuant to subsection A1 of this section. The plan shall also state the name and phone number of the person or entity responsible for implementation of each control measure.
B. Goals And Criteria: The proposed measures and controls described in the plan shall be designed to meet the following goals and criteria:
1. Prevent Or Minimize Discharge: The proposed measures and controls shall be designed to prevent or minimize, to the maximum extent practicable, the discharge of sediment, debris and other construction related pollutants from the construction site by storm water runoff into the storm drainage system.
2. Prevent Or Minimize Construction Debris: The proposed measures and controls shall be designed to prevent or minimize, to the maximum extent practicable, the deposit, discharge, tracking by construction vehicles, or dropping of mud, sediment, debris or other potential pollutants onto public streets and rights of way. Any such discharge shall be cleaned up and removed immediately upon notification to the permittee or when it otherwise comes to the attention of the permittee. At a minimum, the deposit or discharge shall be cleaned and removed at the end of the work shift in which the deposit occurred, or at the end of the workday, whichever comes first.
3. BMPs: The proposed measures and controls shall consist of best management practices (BMPs) available at the time that the plan is submitted. BMPs may include, but shall not be limited to, temporary silt or sediment fences, sediment traps and detention ponds, gravel construction entrances and wash down pads to reduce or eliminate off site tracking, straw bale sediment barriers, establishment of temporary grasses and permanent vegetative cover, use of straw mulch as a temporary ground cover, erosion control blankets, temporary interceptor dikes and swales, storm drain inlet protection, check dams, subsurface drains, pipe slope drains, level spreaders, rock outlet protection, reinforced soil retaining systems, and gabions.
4. Stabilization: The proposed measures and controls shall be designed to preserve existing vegetation, where possible. Disturbed portions of the site shall be stabilized. Stabilization practices may include temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, preservation of mature vegetation, and other appropriate measures. Use of impervious surfaces for stabilization should be avoided. Stabilization measures shall be initiated as soon as practicable in disturbed portions of the site where construction activities have temporarily or permanently ceased, but in no case more than fourteen (14) days after the construction activity in that portion of the site has temporarily or permanently ceased, except under the following circumstances:
a. If the initiation of stabilization measures by the fourteenth day after construction activity temporarily or permanently ceases is precluded by snow cover or frozen ground conditions, stabilization measures shall be initiated as soon as practicable; or
b. If construction activity on a portion of the site is temporarily ceased, and earth disturbing will resume within twenty one (21) days, temporary stabilization measures need not be initiated on that portion of the site.
5. Minimize Risk Of Discharge Of Other Materials: The proposed measures and controls shall be employed to minimize the risk of discharge of construction related pollutants (such as paint, thinners, solvents and other chemicals) from the construction site. Such measures may include implementation of storage practices to minimize exposure of the material to storm water as well as spill prevention and response. (Ord. 07-14, 6-12-2007)
