Qualifying Storm Event (QSE)

14

New Definition for a Qualifying Storm Event

A Qualifying Storm Event (QSE) is a precipitation event that:

a. Produces a discharge for at least one drainage area; and, b. Is preceded by 48 hours with no discharge from any drainage area.

Sample Frequency Requirements

15

Increased Sample Frequency Requirements:

Dischargers shall collect storm water samples from all locations that discharge storm water associated with industrial activity for 2 QSEs within the first half of each reporting year (July 1 to December 31) and 2 QSEs within the second half of each reporting year (January 1 to June 30).

No More Excuses for Not Collecting Samples: Samples from each discharge location shall be collected within 4 hours of:a. The start of the discharge; orb.

storm water Dischargers. Subject to change in future as more are added.

Field Measurements

19

Field Measurements: Specific Conductance (SC) is no longer required

Due to the 15 minute holding time, measurements for pH usually are made in the field. This can be done using a wide range pH litmus paper.

However, if the discharger exceeds Numeric Action Levels(NALs), then the permit requires the use of a calibrated pHmeter. This device must meet minimum standards for this type of field sampling and must be calibrated in accordance with the manufacturers specifications.

Numeric Action Limits Exceedances

21

Two Types of Numeric Action Limits (NAL) Exceedances:

1) Annual NAL Exceedance – When the average of the annual sample results for a parameter are exceeded (refer to Annual NAL on Table 5). Note: Sites can take additional samples (>4 per year) if they want to try and lower the annual average for a parameter.

2) Instantaneous Maximum NAL Exceedance - when two or more results in a reporting year exceed (for TSS or O&G) or are outside the pH range per Table 5.

Exceedance Response Actions (ERAs)

22

Baseline Status – No Exceedance All Dischargers start NOI Coverage at Baseline Status.

Level 1 Status - NAL Exceedance immediately triggers Level 1 status for parameters exceeded.

Within 60 days discharger shall evaluate the SWPPP and pollutant sources.

ASAP, or by October 1 following the reporting year, dischargers shall implement additional operational and/or source control BMPs, revise the SWPPP, and submit via SMARTS a QISP prepared Level 1 ERA evaluation.

Exceedance Response Actions (ERAs)

23

Level 2 Status – Structural/Treatment Control A Level 1 status immediately changes to Level 2 for parameters that have an NAL exceedance in any subsequent reporting year.

Within 120 days discharger shall:a. Evaluate the SWPPP and pollutant sources and identify whether

additional structural and/or treatment control BMPs are necessary.

b. Submit via SMARTS a QISP prepared Level 2 ERA Technical Report including implementation schedule for design & construction of treatment and/or structural source control BMPs or a schedule to submit a Demonstration Technical Report.

ASAP, or within one year discharger shall: implement structural and/or treatment control BMPs, revise the SWPPP, and (if applicable) submit Demonstration Technical Report.

Demonstration Technical Reports

24

BAT/BCT Compliance Demonstration Technical Report:

Evaluate cost of technology in relation to effluent reduction benefits, age of equipment &

facilities involved, process employed, engineering aspects of the various types of control

techniques, process changes, and non-water quality environmental impact (i.e. energy

requirements)

Non-Industrial Source Pollutant Demonstration Technical Report:

Discharger must demonstrate that the pollutants causing the exceedances are solely

attributable to storm water run-on from adjacent properties or from non-industrial portions of

the Discharger’s property, or from aerial deposition. Requires a quantification of the relative

contributions of the pollutant from run-on, non-industrial sources, or aerial deposition.

Demonstration Technical Reports

25

Natural Background Demonstration Technical Report includes:

A summary of all data previously collected by the Discharger or others that describe the levels of

natural background pollutants in the storm water discharge

A summary of any research and published literature that relates the pollutants evaluated at the

facility;

A map showing the reference site location in relation to facility along with available land cover

information;

Reference site and test site elevation;

Available geology and soil information for reference and test sites;

Photographs showing site vegetation;

Site reconnaissance survey data regarding presence of roads, outfalls, or other human-made

structures; and

Records from relevant state or federal agencies indicating no known mining, forestry, or other human

activities upstream of the proposed reference site.

COMPLIANCE GROUPS & LEADERS

26

Baseline/Level 1 Compliance Group (CG1) and Baseline/Level 1 Compliance Group Leader (CGL1) Requirements

A group of Dischargers of the same industry type (facilities with similar types of industrial activities, pollutant sources, and pollutant characteristics) may form a CG1.

The CG1 shall select a CGL1 to assist with all compliance activities in this General Permit other than Level 2 ERA compliance activities. For example SWPPP development, monitoring, visual observations and inspections. The number of samples required per year is reduced from four to two.

COMPLIANCE GROUPS & LEADERS

27

A CGL1 must prepare a Consolidated Level 1 ERA Report , which provide a description of the common industrial pollutant sources, BMPs & ERAs, and also the industrial pollutant sources, BMPs & ERAs that are not common between the CG1 Participants.

The CGL1 shall revise the Consolidated Level 1 ERA Report in accordance with any comments received from the Water Boards

The CGL1 shall inspect all the facilities of the CG1 Participants at a minimum of once per reporting year (July 1 to June 30).

The CGL1 shall update the Consolidated Level 1 ERA Report as needed to address additional CG1 Participants that trigger the ERA Level 1 reporting requirements
