Appendix 1: ANSWER Risk determination worksheet Appendix 2.1: Post-construction water balance performance standard

Appendix 2: ANSWER Post-construction water balance performance standard standard spreadsheet for measuring post-construction water balance performance

Appendix 3 - ANSWER Bioassessment Monitoring Guidelines

Appendix 4 - ANSWER Adopted/implemented sediment TMDLs.

Appendix 5: ANSWER Glossary

Appendix 6: ANSWER Acronyms

Appendix 7 - Contact Information for State and Regional Water Resources Control Boards.

Rainfall erosion waiver - ANSWER Small building sites (>1 and <5 acres) can self-certify if the rainfall erosivity value (R-value) for their location and timeframe is less than or equal to 5.

ATS (Active Treatment Systems) - Answer On construction sites, typical erosion and sediment measures may not be successful in controlling rapid erosion. In such cases, or where stormwater discharges from the site may cause or contribute to a water quality standard exceedance, an Active Treatment System (ATS) may be required. Furthermore, an ATS may be appropriate when site constraints prevent the construction of a properly sized sediment basin, when clay and/or very erosive soils are present, or when the slope lengths are extremely steep or lengthy.

What are the NALs for Risk 2 and 3? pH <6.5 and >8.5. Turbidity exceeds 250 NTU.

Receiving Water Monitoring Triggers - Answer for Risk Level 3 pH <6.0 or >9. Turbidity exceeds 500 NTU.

What constitutes a qualifying event? - ANSWER 1/2" or more discharges over some time in which there is no break in rain for more than 48 hours.

What permit registration documents are required prior to construction? - Answer Notice of Intent (NOI) Risk Assessment Post-construction BMP Information Site Map. Storm Water Pollution Prevention Plan. Annual fee Signed Certification Statement

What is sedimentation? ANSWER: Deposition of degraded material

The Three S's of Wind Erosion: Saltation

C = Crop Management. P = supporting practices (farming direction, strip cropping, etc.).

Sediment Risk Levels: Low Risk (<15 tons/acre) Medium Risk: >=15 and <75 tons/acre. High Risk >= 75 tons/acre.

5 distinct BMP categories - ANSWER Good Site Management - "Housekeeping" Non-stormwater Management Erosion Control Sediment Control Run-on/off controls

Different options for sediment control - ANSWER: Silt fence Fiber Roll Compost Sock Curb Cutbacks

ATS - Answer Any treatment involving chemical coagulation, chemical flocculation, or electrocoagulation to minimize tubidity caused by fine suspended particles.

What are the two types of ATS operations? - Answer Flow Through Batch ATSs are operated in two different modes: batch and flow-through. Batch treatment is defined as Pump-Treat-Hold-Test-Release. Water is retained in a basin or tank during batch treatment and not discharged until the treatment is completed. Batch treatment is the process of storing or recirculating treated water in a holding basin or tank(s) until treatment is complete or the basin or storage tank(s) is full. Flow-Through treatment involves pumping water from the runoff collection system or storm water holding pond straight into the ATS, where it is treated and filtered as it passes through the system before being discharged. "Flow-Through Treatment" is also known as "Continuous Treatment."

Required documents for ATS - ANSWER Operation and Maintenance Manual. Monitoring, sampling, and calibration records Health and Safety Plan Spill Prevention Plan

What are the ATS's reporting requirements? - ANSWER Upload field data to smarts at least once every 30 days. For NEL infractions, upload the report within 24 hours. Toxicity or water quality standards that have been exceeded must be reported immediately.

What monitoring and sampling are necessary at Risk Level 1? - ANSWER Quarterly non-storm water observations.

What is the Suspended Sediment Concentration (SSC)? - ANSWER The dry weight of all sediment from a given volume of water-sediment combination.mg dry sediment per liter of mixture.

What are the requirements for non-visible sampling? - ANSWER Samples must be obtained within two hours after the start of discharge. Two samples are required for comparison purposes: one of the attached runoff and one of the unaffected runoff.

ANSWER Construction Site Monitoring Program.

What type of record-keeping is required? - ANSWER: Daily rain gauge readings Observation Records Calibration and testing results from the field. Lab reports, chain of custody documents, and QA/QC records REAPs Annual and noncompliance reports Corrective actions and follow-up records

What is the time frame for submitting paperwork if emergency construction is required. - ANSWER: 5 days. Brief description from the discharger 30 days: Submit all PRDs.

Which BMP tool should you go for first? - ANSWER Erosion Control BMPs

LUP across several properties - ANSWER: Owner of LUP's responsibilities

How soon after a NAL exceedance must the data be uploaded? - Answer: 10 days.

Who submits the permit registration documents—ANSWER LRP or permitted signatory?

Which rule establishes a basis for regulating municipal and industrial dischargers? ANSWER CWA

Non-storm water discharges are approved if they meet the NALs for pH and turbidity. Do not cause or create violations of water quality requirements. Comply with BMPs recommended in the SWPPP. Not feasible to eliminate.

ANSWER Primary BMP: Erosion control. Secondary: Sediment Controls
