<br />B, STORM WATER MANAGEMENT PLAN (SWMP) —GENERAL REQUIREMENTS (cont.)
<br />2. The SWMP shall:
<br />a) Identify all potential sources of pollution which may reasonably be expected to affect the quality of stormwater
<br />discharges associated with construction activity from the facility;
<br />b) Describe the practices to be used to reduce the pollutants in stornrwater discharges associated with construction
<br />activity at the facility; and ensure the practices are selected and described in accordance with good engineering
<br />practices, including the installation, implementation and maintenance requirements; and
<br />C) Be properly prepared, and updated in accordance with Part I.D,5,e, to ensure compliance with the terms and
<br />conditions of this permit,
<br />3. Facilities must implement the provisions of the SWMP as written and updated, from commencement of construction activity
<br />until final stabilization is complete, as a condition of this permit. The Division reserves the right to review the SWMP, and
<br />to require the permittee to develop and implement additional measures to prevent and control pollution as needed,
<br />4. The SWMP may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans under section 31 [of
<br />the CWA, or Best Management Practices (BMPs) Programs otherwise required by a separate CDPS permit, and may
<br />incorporate any part of such plans into the SWMP by reference, provided that the relevant sections of such plans are

<br />C. STORMWATER MANAGEMENT PLAN (SWMP) — CONTENTS
<br />The SWMP shall include the following items, at a minimum.
<br />Site Description. The SWMP shall clearly describe the construction activity, to include:
<br />a) The nature of the construction activity at the site,
<br />b) The proposed sequence for major activities.
<br />c) Estimates of the total area of the site, and the area and location expected to be disturbed by clearing, excavation,
<br />grading, or other construction activities.
<br />d) A summary of any existing data used in the development of the site construction plans or SWMP that describe the
<br />soil or existing potential for soil erosion.
<br />e) A description of the existing vegetation at the site and an estimate of the percent vegetative ground cover.
<br />f) The location and description of all potential pollution sources, including ground surface disturbing activities (see
<br />Part 1,A,2,b), vehicle fueling, storage of fertilizers or chemicals, etc.
<br />g) The location and description of any anticipated allowable sources of non-stonnwater discharge at the site, e.g.,
<br />uncontaminated springs, landscape irrigation return flow, construction dewatering, and concrete washout.
<br />h) The name of the receiving water(s) and the size, type and location of any outfall(s). If the stonnwater discharge is to
<br />a municipal separate storm sewer system, the name of that system, the location of the storm sewer discharge, and the
<br />ultimate receiving water(s).
<br />2. S'itghlan. The SWMP shall include a legible site map(s), showing the entire site, identifying:
<br />a) construction site boundaries;
<br />b) all areas of ground surface disturbance;
<br />c) areas of cut and fill;
<br />d) areas used for storage of building materials, equipment, soil, or waste;
<br />e) locations of dedicated asphalt or concrete batch plants;
<br />f) locations of all structural BMPs;
<br />g) locations of non-structural BMPs as applicable; and
<br />h) locations of springs, streams, wetlands and other surface waters.
