(A) The SWPPP shall include sufficient information about the proposed activities and land parcel(s) to form a clear basis for discussion and review and to assure compliance with all applicable requirements of this chapter.
(B) The plan shall be consistent with the data collection, data analysis, land plan preparation guidelines in the current Rhode Island Soil Erosion and Sediment Control Handbook, prepared by the U.S. Department of Agriculture, Soil Conservation Service, R.I. Department of Environmental Management, R.I. State Conservation Committee, and at a minimum shall contain:
(1) Narrative description. A description of the proposed land disturbing activity, estimates of the total area of the site and the total area of the site expected to be disturbed, and any proposed sequencing of project; soil erosion and sediment control measures, and measures to be installed to control other wastes that could result from the proposed activity; and a description of any potential sources of pollution that may be expected to affect the 1uality of stormwater discharges from the site. Supporting documentation, such as a description of the drainage area and the existing site, and soil maps shall be provided as required by the Building Official or designee.
(2) Construction drawings. Drawings illustrating in detail existing and proposed contours, drainage features and limits of vegetation; limits of clearing and grading; the location of soil erosion and sediment controls stormwater management measures, and controls for other wastes; detail drawings of the controls and measures; the location of stock piles and borrow areas; sequencing and staging of land disturbing activities; and other such information needed for construction.
(3) Erosion and sediment controls. A description including construction details appropriate to the site, for both vegetative and structural practices. Vegetative BMPs are designed to preserve existing vegetation where attainable and revegetate open areas as soon as practicable after grading or construction. Structural BMPs divert flows from exposed soils, filter runoff, store flows or otherwise limit runoff from coming into contact with exposed, unvegetated areas of the site and to prevent sediments and/or other pollutants from leaving the site.
(4) Post construction stormwater management. A description of measures that will be installed during the construction project to control pollutants in stormwater discharges that will occur at the site after the construction operations have been completed. These measures shall be consistent with the requirements of the stormwater ordinance. Maintenance activities for these measures shall be described in accordance with division (B)(6) below.
(5) Other controls.
(a) Waste disposal. A description of the other controls, including construction details appropriate for the site. to eliminate the discharge of other construction wastes found on the construction site. All types of waste generated at the site shall be disposed of in a manner consistent with state law and/or regulations.
(b) Good housekeeping. Good housekeeping measures to provide for the minimization of exposure of construction debris to precipitation and for the proper disposal of such debris shall be specified.
(c) Spill prevention. Areas where potential spills can occur shall be identified. The potential tor spills to enter the stormwater drainage system, shall be eliminated wherever feasible.
(6) Maintenance plan. A description of procedures to maintain. in good and effective operating condition, vegetation stormwater control measures, and other protective measures, identified in the site plan.
(7) Other information. Other information or construction plans and details as deemed necessary by the Building Official for thorough review of the plan prior to action being taken as prescribed in this chapter. Withholding or delaying submission of such information may be reasons for the Building Official to judge the application incomplete and grounds for disapproval.
