Purpose of Today’s Session
Explain Permit Reissuance Schedule and Public Process
Explain changes proposed by Ecology
Answer questions
3
Reissuance Background
Federal regulations: NPDES Permits cant be issued for more than 5 years
Current Permit expires Jan 1, 2015
Federal regulations: Facilities must re-apply 180 days before expiration Ecology sent instructions in May Electronic Applications Due date: July 5, 2014
4
Reissuance Schedule
May 7: Ecology released Draft Permit and Fact Sheet Began Public Comment Period
May-June: Public Workshops/Hearings June 20: Close Public Comment Period
Ecology reviews public comments Makes appropriate revisions
5
Reissuance Schedule
Nov 19: Issue Final Permit Response to Comments Permit coverage issued to facilities Appealable
Jan 1, 2015: Final Permit Effective Supersedes existing permit

Proposed Changes
Most permit conditions unchanged Revisions proposed to:
Improve clarity and reduce confusion; Implement new Federal Regulations; Streamline Level 3 Engineering Reports; Improve protection of Puget Sound
Sediment Cleanup Sites.

S1. Permit Coverage
Facilities engaged in Industrial activity - Table 1 Manufacturing Warehousing Processing Waste Disposal/Recycling Transportation – if vehicle maintenance activity,
equipment cleaning operations, or airport de-icing
and
Stormwater discharges to surface waters or storm drain connected to surface waters
11
Proposed Changes
Facilities covered under the Permit SWPPP/Best Management Practices Sampling Benchmarks Corrective Actions Impaired Waters Reporting
S3. Stormwater Pollution Prevention Plan (SWPPP)
Must use “Applicable” BMPs from Ecology Stormwater Manuals 2012 Western WA Manual 2004 Eastern WA Manual
Mandatory Best Management Practices

17
S4. Sampling
Sample Timing One sample per quarter Sample “1st Fall Flush” on or after Oct 1st Sample within 12 hrs of discharge
Sampling Locations All discharge points sampled unless
“substantially identical” If numeric effluent limits, must sample
those parameters at each discharge point.
18
S4. Sampling
“Consistent Attainment” of Benchmark – Suspend Sampling 8 consecutive quarters “No Discharge” quarters don’t reset the
consistent attainment tally
19
S4. Sampling
Quarterly Averaging Clarified If multiple samples collected – average
results and compare to benchmark Language added to clarify how to calculate
quarterly average when multiple samples are collected during a single day.

S5. Effluent Limits
New Federal Regulations 2012 Federal Effluent Limitation Guidelines and New
Source Performance Standards for Airport Deicing Airports with 1000+ annual jet departures
Daily Max Limit: 14.7 mg/L Total Ammonia (as N); or
Use “non-urea containing deicers”; certify in Annual Report
New Airports with 10,000+ annual jet departures Not eligible for ISGP Need Individual Permit

Proposed Changes

S8. Corrective Actions
3 Types of Corrective Actions: Level 1 – Operational Source Control BMPs Level 2 – Structural Source Control BMPs Level 3 – Treatment BMPs
26
S8. Corrective Actions
3 Types of Corrective Actions: Level 1 – Operational Source Control BMPs
• Each time benchmark exceeded Level 2 – Structural Source Control BMPs
• Benchmark exceeded 2 Quarters/Year Level 3 – Treatment BMPs
• Benchmark exceeded 3 Quarters/Year
27
Level 1 - Operational Source Control
Example: Increase Sweeping Example: Clean Up Spills
28
S8. Corrective Actions
3 Types of Corrective Actions: Level 1 – Operational Source Control BMPs
• Each time benchmark exceeded Level 2 – Structural Source Control BMPs
• Benchmark exceeded 2 Quarters/Year Level 3 – Treatment BMPs
• Benchmark exceeded 3 Quarters/Year
29
Level 2 - Structural Source Control
Example: Install Cover Example: Coat Roof30
S8. Corrective Actions
3 Types of Corrective Actions: Level 1 – Operational Source Control BMPs
• Each time benchmark exceeded Level 2 – Structural Source Control BMPs
• Benchmark exceeded 2 Quarters/Year Level 3 – Treatment BMPs
• Benchmark exceeded 3 Quarters/Year
31
S8. Corrective Actions
Case by Case: Extensions and Waivers If not feasible to meet deadline, Ecology may
approve deadline extension (Permit Mod)
If corrective action is not feasible/necessary, Ecology may approve waiver (Permit Mod)
Require public notice & subject to appeal
32
Level 3 – Treatment
Example: Media Filter33
Level 3 – Proposed Changes
Deleted requirement for “full” engineering report (Chapter173-240 WAC);
Replaced with checklist of 7 required elements
Operations & Maintenance (O&M) Manual due 30 days after construction
34
Level 3 – Proposed Changes
35
Level 3 – Proposed Changes
Reduce cost of engineering reports Streamline review/approval process Will not reduce the quality of treatment
systems
36
Level 3 – Proposed Changes
While a time extension is in effect, benchmark exceedances (for the same parameter) do not count towards additional Level 2 or 3 Corrective Actions.
