General SWMP Requirements The following administrative requirements apply to the SWMP written to address all drainage areas contributing runoff to the outfalls referred to in this Part. The permittee shall modify the existing facility SWMP to comply with the requirements of this permit within 90 days of the permit effective date. a. SWMP requirement: The permittee must develop, implement, and maintain a SWMP. The SWMP shall be prepared in accordance with good engineering, hydrologic and pollution control practices (the SWMP need not be prepared by a registered engineer). The permittee must modify the SWMP to reflect current site conditions. b. Submission: The permittee must submit the SWMP to the Division if requested. c. Signatory Requirements: The permittee must sign the SWMP in accordance with the REPORTING AND RECORDKEEPING section; this requirement applies to the original SWMP prepared for the facility, and each time the permittee modifies a SWMP. d.

Unless otherwise provided by the Division, the permittee shall have 30 days after notification to make the necessary changes to the SWMP and implement them. b) The Division may require the permittee to submit the modified SWMP to the Division. c) If the Division determines that the permittee's stormwater discharges do not, or may not, achieve the effluent limits required by this permit, the Division may require the permittee, within a specified time period, to develop and implement a supplemental control measure action plan, which describes additional SWMP modifications to adequately address the identified water quality concerns.
