Changes in the New Permit:What You Need to Know Now and Next Year

• SMARTS: Your results are online and transparent to the Water Board, Third-Party Environmental Groups and Attorneys

• Exceedances: Numeric Action Levels (NALs) can trigger consequences for annual and instantaneous maximum results

Annual (annual average of all results for a given parameter)

Instantaneous Maximum (when two or more results within a reporting year for the basic parameters of pH, TSS and O&G exceed the instantaneous maximum NAL value)

• Baseline: Storm water year 2015-2016 is a baseline year - fresh start

• Level 1: Exceedance Response Action (ERA) Evaluation and Report by QISP

• Level 2: Exceedance Response Action (ERA) Action Plan and Technical Report with Demonstrations by QISP

What You Need to Know About Level 1

Facilities with high enough NAL exceedances fall intoLevel 1 Status for the 2016-2017 storm water year

What Does Level 1 Require?

• An evaluation by a QISP of the facility’s pollutant sources and drainage areas must be completed by October 1st, 2016

• The evaluation will specify BMPs to prevent future NAL exceedances

• A report prepared by a QISP must be completed and new BMPs must be implemented by January 1st, 2017

• The report will describe SWPPP revisions and additional BMPs• The report must be certified and submitted via the

SMARTS database• Note – The report and new BMPs aren’t due until

1-1-2017, but you are on the hook for your results!

What You Need to Know About Level 2

Permit Requirements for Level 2

Level 2 ERA Action Plan • Certify and submit Level 2 ERA Action Plan (prepared by QISP) by January 1st• Identify demonstration discharger will perform for each new NAL exceedance• List of possible demonstrations:

Certify and submit QISP identification information via SMARTS Must address drainage areas and additional BMPs to be implemented Includes schedule and detailed description of tasks to complete demo

Level 2 ERA Technical Report• Certify and submit Level 2 ERA Technical Report (prepared by QISP)• The Level 2 ERA Technical Report shall include one or more of the following

demonstrations: Industrial Activity BMPs Demonstration Non-Industrial Pollutant Source Demonstration Natural Background Pollutant Source Demonstration

• Level 2 ERA Technical Report submittal by following January 1st

Gravity Separation – Settling and Floating

Let gravity do the work in separatingthe solids once flocculant is applied

Reduce Solids – Reduce Exceedances:

The use of settling ponds, gravel channels, and other water flow BMPs can improve sample results quickly and affordably

Minimum BMPs RequiredThe Industrial General Permit (IGP) includes minimum BMPs

Minimum BMPs • Good Housekeeping • Preventive Maintenance • Spill and Leak Prevention• Material Handling / Waste Management • Erosion/Sediment Controls • Employee Training Program • Quality Assurance/Record Keeping

Advanced BMPs • Exposure Minimization BMPs (storm resistant shelters)• Water Containment and Discharge Reduction BMPs

(divert, infiltrate, reuse, contain, or reduce runoff)• Treatment Control BMPs (mechanical, chemical, biologic)• Other Advanced BMPs

Basic BMPs: Wattles and Socks

What are Basic BMPs?

• Wattles – sediment removal• Metal Socks – dissolved metals removal• Flocculant Socks – sediment removal, oil encapsulation, solids clump and settle• Oil Booms and Pillows – oil removal• Drain Filters – sediment removal and debris control• Metal Removing Catch Basin Filter – dissolved metals removal

StormPROOFBasic BMP Kit Deployment

In the direction the water is flowing,

place wattle closest to the drain

or sample point, with the metal media sock, oil

pillow and flocculant sock layered in order after the wattle.

Concrete Company BMP Case Study

Overview of Pollutant Challenges

• High Total Suspended Solids (TSS) and high Iron (Fe) were problems for this facility due to concrete dust.

• Industrial material stockpiles were causing high TSS – the solids needed to be filtered.

• Run-off needed to be minimized to decrease pollutants.

• Storm water flow needed to be slowed to promote storm water retention to aid settling of solids.

• Industrial materials needed to be covered to avoid exposure.

• Perimeter was eroding and discharging into a creek.

• Run-on from neighboring businesses was causing problems.

• Third Party lawsuit for historical exceedances.17

Concrete Company BMP Case Study (cont’d.)BMP Recommendations Implemented

• Drive-through gravel-line basins have been excavated in key areas of storm water flow to promote storm water retention and slow down storm water velocity which facilitates the settling of solids susceptible to suspension in fast-moving water.

• Flocculant was also broadcast into the basins, upstream of the basins and across the site in unpaved areas to aid in the clumping of fine solids.

• Straw wattles are deployed in front of material stockpiles prior to rain events to filter solids and minimize the runoff of aggregate materials which have been identified as a source for TSS and Fe.

• Tarps are deployed over material stockpiles prior to rain to minimize the exposure of storm water to aggregate materials which have been identified as a source for TSS and Fe. Industrial wattles deployed in front of materials.

• Discharge has been eliminated at Outfall 2. • A berm is installed along the north perimeter to prevent erosion and

eliminate direct discharge into a water body along one point.• Run-on from neighboring businesses eliminated via perimeter

re-grading.18

Additional BMP Recommendations

• Vacuum areas around batch operations and aggregate unloading areas to minimize buildup.

• Regularly inspect integrity of bunkers, transfer equipment, and support equipment and repair as necessary.

• Regularly inspect and dispose of products no longer usable in designated waste dumpsters and keep lids closed/covered to prevent dispersal by wind or rain.

• Remove packaged finished products from exposure prior to rain events.
