Industrial Stormwater Discharge Monitoring Report - 1200-Z Permit
All Sections
·         Organize data first by sample location/outfall.
·         For each location, provide the data.
·         Where applicable, the spreadsheet will calculate the geometric mean.
·         [NAME] only pages needed for your facility.
·         Report non-detects as "ND" along with the applicable method detection limit or minimum quantification limit in parentheses; for example ND (0.001).
·         If you collected more data than will fit in the standard form (for example, more than 4 locations or more than 4 samples per location), fill out additional pages as needed.
[NAME]: [NAME]
·         Required for all permit holders
·         Sample 4 times per year, every year, unless a monitoring waiver applies.
·         Geomean reporting is required only in the second year of permit coverage.
[NAME]: Additional Sampling
Do not submit this page in the years after you have submitted the required number of samples for each sampling point.
Cadmium, nickel and zinc
·         Required for all permit holders.
·         Collect a total of 8 samples during the first three years of the permit coverage.
Mercury
·         Required only for auto salvage and scrap recycling facilities (SIC 5015 and 5093).
·         Collect a total of 4 samples during the first three years of permit coverage.
PCBs
·         Required only for scrap recycling facilities (SIC 5093).
·         Collect a total of 4 samples during the first 3 years of permit coverage.
·         Report as the sum of the following aroclors 1016, 1221, 1232, 1242, 1248, 1254, 1260.
·         If the result for an aroclor is non-detect, do not include it in the sum.
·         If all aroclors are non-detect, report the results as ND (0.002).
Sector tab: Sector-Specific Benchmark Sampling
·         Required only of some sectors (please refer to your permit assignment letter).
·         If your facility does not have sector-specific benchmark requirements listed in your permit assignment letter, do not submit this section.
·         Sample 4 times per year, every year.
·         Different parameters are required for different sectors. Sample and report only those parameters required for your sector (you may only need to submit one of the two pages).
·         Geomean reporting is not required, but may be used to obtain a monitoring waiver.
Impairment tab: Impairment Sampling
·         Different parameters are required for different locations. Sample and report only those parameters required for your facility.
·         Many facilities will not have impairment sampling requirements (see your assignment letter). If your facility does not have impairment sampling requirements, do not submit this page.
·         [NAME] are based on receiving water.
·         Sample 2 times per year, every year.
·         If your permit was assigned on or before March 17, 2013. use the first (in blue) reference
concentration for chromium(hex), dichloroethylenes, and dieldrin.
·         If your permit was assigned after March 17, 2013. use the second (in green) reference
concentration for chromium(hex), dichloroethylenes, and dieldrin.
Limits tab: Discharge Limit Sampling
·         Required only for the indicated sectors (see your assignment letter).
·         Sample once per year (unless an exceedance of the limit occurs then check your permit), every year.
·         Sample and report only those parameters required for your facility.
If a parameter is required in multiple sections
Report the results only in one section. Use the table below to determine which section to report in, and follow the sampling requirements for that section. Note, however, that all relevant benchmarks, impairment reference concentrations, and limits must be applied to the sample results.
Examples:
·         A parameter is required as sector-specific benchmark, impairment parameter, and additional parameter. Sample 4 times per year, every year, and report in the sector-specific benchmark section. [NAME] criteria and impairment reference concentrations apply.
·         A parameter is required as an impairment parameter and sector-specific limit. Sample 2 times per year, every year, and report in the impairment section. Impairment reference concentrations and sector-specific limits apply.
If your sampling requirements are: |  |  |  |  | Then report in the section below:
[NAME] | Sector-specific [NAME] | Impairment | Sector-specific Limits | “Additional Sampling”
4/year | 4/year | 2/year | 1/year | 8 or 4 total in 3 years
Yes | * | * | * | Yes | [NAME]
 | Yes | Any combination |  |  | Sector-Specific Benchmark
 |  | Yes | Any combination |  | Impairment
 |  |  | Yes | Yes | Additional**
*Statewide benchmark parameters are never required in the sector-specific benchmark, impairment, or additional sections.
** This combination only occurs for “hazardous waste landfills subject to effluent limitations in 40 CFR Part 445 [NAME]” These facilities must sample for total chromium at least once per year, and must collect a total of 8 samples during the permit term. Collecting two samples per year is recommended in order to fulfill both requirements.
