  1. Purpose of Stormwater Pollution Prevention Plans (SWP3s) for Industries Richard Smith Resource Management Conference Tulsa Garden Center March 26, 2015

  2. What Is An SWP3? • Basically an operations manual or operating procedures document. • Required in all three stormwater permits in Oklahoma: • OKR05 – Industrial Activities • OKR10 – Construction Activities • OKR04 – Small Municipal Separate Storm Sewer Systems (SMS4s) • Each permit has specific instructions for SWP3 contents and uses.

  3. How SWP3 Is Referenced in OKR05 • Part IV in OKR05 defines the contents of the SWP3. • There are numerous references within the rest of OKR05 to using the SWP3. • Most require that permit actions be documented in the SWP3. • Others refer to taking actions in accordance with the SWP3. • This presentation will focus on the most important SWP3 requirements in OKR05.

  4. Part I: Background • 1.2.5.7.B.b – Any applicable requirements from an approved TMDL must be in your SWP3. • 1.2.6.3 – SWP3 must be submitted to ODEQ when filing the NOI if the facility is within a sensitive watershed or ORW (see Exhibit 1). • 1.3.3.2 – You must continually update and implement your SWP3 and BMPs. Thoroughly understand acronyms and terms, such as NOI, NOT, TMDL, ORW, BMPs, NELM, etc.

  5. Part III: Special Conditions • 3.1 – Hazardous Substances or Oil: Must address prevention or minimizing releases of Hazardous Substances or Oil. • 3.1.2 – Must modify your SWP3 within 14 calendar days of knowledge of a release of Hazardous Substances or Oil. • 3.1.2 – Must review the SWP3 and identify measures to prevent reoccurrences, and modify the SWP3 where appropriate. • 3.3 – If you have a discharge that causes or has the reasonable potential to cause a violation of water quality standards, you must document your actions in the SWP3 that you will take to ensure no further discharges will occur.

  6. Part V: Monitoring Requirements • 5.1 – Quarterly Visual Monitoring: • 5.1.3 – You must maintain your quarterly visual examination reports on site with the SWP3. • 5.1.4 – Any monitoring waiver certifications must be maintained with the SWP3. • 5.2.4.2 – For NELM sampling, you must document in the SWP3 why it was not possible to collect a stormwater runoff sample within the required first 30 minutes of discharge.

  7. Part VI: Reporting • 6.1 – Reporting Results of … NELM. • 6.1.2 – Visual monitoring results of NELM must be retained with the SWP3. Only submit results to ODEQ if requested.

  8. Part VII: Retention of Records • 7.1 – Documents. • 7.1.2 – You must retain your SWP3 until 3 years after the last modifications or amendments to the plan, and at least 3 years after termination of permit coverage. • 7.2 – Accessibility. During the life of permit coverage, you must retain the SWP3 at the facility or other local location accessible to ODEQ.

  9. Part VIII: Standard Permit Conditions • 8.7 – Signatory Requirements (including for SWP3s). • 8.7.1 – Signing NOIs and NOTs(applies also to signing SWP3s). • 8.7.1.1 – For a corporation: by a responsible corporate officer. • 8.7.1.2 – For a partnership or sole proprietorship: by a general partner or the proprietor. • 8.7.1.3 – For a municipality or…agency: by either a principal executive officer or ranking elected official. • 8.7.2 – Sign All Required Reports.

  10. Exhibit 1: Endangered Species • B: Procedures [to ensure protection of endangered species] • B. Step 2.1 – If facility is within sensitive waters and watersheds, you must incorporate the following measures into the SWP3: • B. Step 2.1.a – Pollutants must be captured, treated and disposed of and properly managed to minimize or eliminate stormwater contact. • B. Step 2.1.b – If you must do NELM, you must include in the SWP3 steps to prevent the removed pollutants from entering a stormwater stream.

  11. Exhibit 1: Endangered Species (cont.) • B. Step 2.1.c – You must have a schedule of inspection practices in your SWP3 that will ensure that control measures work. • B. Step 2.1.c – Monthly inspections must be conducted for areas of the facility with “significant activity”. • B.
