This document discusses requirements for facilities covered by the Multi-Sector General Permit (MSGP) and Spill Prevention Control and Countermeasures (SPCC) plans. It outlines that facilities must develop Stormwater Pollution Prevention Plans that include best management practices, training, inspections, and monitoring to prevent pollution from entering waterways. It also provides guidance on SPCC plan requirements for facilities that store oil, such as having secondary containment and procedures to prevent and respond to spills. Facilities must certify and update these plans regularly to maintain compliance.

1. Multi-Sector General Permit
(MSGP)
Spill Prevention Control and
Countermeasures (SPCC)

2. Multi-Sector General
Permit (MSGP)

3. What is the Definition of
“No Exposure?”
• All industrial materials or activities are
protected by a storm resistant shelter to
prevent exposure to rain, snow, snowmelt,
and/or runoff.
• Storm resistant shelter not required for:
– Sealed containers
– Adequately maintained vehicles
– Final products intended for outdoor use

4. No Exposure Limitations
• Available on a facility-wide basis only
• Permit required when condition of “no
exposure” no longer exists

5. Stormwater Pollution Prevention Plan
• Develop and Implement a Storm Water
Pollution Prevention Plan (SWPPP)
• Facility specific
• Develop, implement, and maintain

6. Pollution Prevention Team
• Identify personnel responsible for developing
and revising SWP3
• Clearly describe each member’s responsibility
• Possible to list a position rather than person

7. Inventory of Exposed Materials
• ALL materials handled that could be exposed to
precipitation or runoff
• Update within 30 days following significant
change
– Significant change in type
– Significant change in practice

8. Spills and Leaks
Spills exposed to stormwater, or occurred within
drainage area for an outfall
Reportable quantity: 30 TAC §327.4
- Land: 25 gallons
- Water: creates oil sheen
Previous 3 years
Updated quarterly

9. Pollution Prevention Measures and
Controls
–Best Management Practices (BMPs)
–Good Housekeeping Measures
–Erosion and Sedimentation Control Measures
–Structural Controls
–Spill Prevention and Response Measures

10. Employee Training
• All employees responsible for SWP3
• Annual training
• Maintain records of training activities
• Educate those not included in training activities

11. Non-Stormwater Discharge
• Within 180 days of filing NOI
• ID and evaluate all non-storm water discharges
• Implement procedures for eliminating any
potential source not permitted
• Document and certify this evaluation

12. Routine Facility Inspections
• Qualified personnel
• At least quarterly (sometimes monthly)
• Use checklist
• Maintain signed documentation in SWP3
• Document any proposed revisions resulting
from inspection

13. Annual Comprehensive Site
Compliance Inspection
• Annual inspection by qualified personnel
• Draft report within 30 days
• Necessary revisions within 12 weeks of report
• No need to report if compliant with all permit
conditions

14. Sampling
• Qualifying storm event
• Rain gauge on-site
• Sample within first 30 minutes of discharge
• Substantially Similar Outfalls
• Inability to sample does not necessarily negate
the requirement to sample

15. Quarterly Visual Monitoring
• Each outfall authorized by this permit
• Visual examination quarterly
• Document results and review by storm water
pollution prevention team

16. Discharge Monitoring Report (DMR)
• Document annual analytical monitoring results
• Monitoring must have been completed by Dec. 31st
for each annual monitoring period
• A copy of the DMR must be retained onsite or
readily available to TCEQ by March 31st of next year
• DMR must be submitted if numeric limitation
exceeded

17. Spill Prevention
Control and
Countermeasures
(SPCC)

18. Do You Need a SPCC Plan?
• Store, process, transfer, distribute, use,
produce, refine oil or oil based products
– Any petroleum product
• Total storage capacity of oil storage is 1,320
gallons or greater
– Only consider containers 55 gallons or larger

19. SPCC Plan
• Outlines the type and location of petroleum
products stored on-site
• Includes procedures for preventing spills
• Includes procedures in case of spill or leak
• Professional engineer must certify if more
than 10,000 gallon storage capacity
• Recertify every 5 years

20. Secondary Containment
• General vs. Specific
• Adequacy of secondary containment
• All containers with capacity of 55-gallons and
greater need secondary containment
• Ensure secondary containment remains
effective

21. Secondary Containment

22. Poorly Maintained Secondary
Containment

23. Inspections
• Tank Containment
• Leak Detection
• Tank Equipment
• Tank Attachments
• Other Conditions

24. Training
• Annual training focused on procedures on
how to prevent a spill and in the event of a
spill
– During installation of a new aboveground storage
tank
– New employee is assigned to oil handling,
transfer, or maintenance responsibilities
• Records: log sheets and training materials

25. Spill Reporting and Documentation
• SPCC Coordinator prepares report for spill of
reportable limit
– Land: 25 gallons
– Water: creates oily sheen
• Notify within 24 hours
– State Emergency Response Center
– TCEQ Regional office (during business hours)
– TCEQ 24-hour spill reporting number
