Georgia Facilities other than those identified in Parts III. C. ( facilities discharging to impaired streams) and VI. A. 2. a. ( specific industries) are not required to perform analytical testing on their storm water discharges associated with industrial activity unless specifically required in writing by the state. Those facilities are required to monitor annually for a set of parameters established by pollutant which causes the impairment or those specifically set out in Part VI. A. 2. a. through t. In addition, the permittee shall perform and document visual examinations of the storm water discharged from each outfall. The examination( s) must be made during normal facility operation at a frequency appropriate to the size and type of industrial activity conducted but no less than once each calendar quarter. No allowances for reductions in sampling are provided. No benchmarks are provided.

Hawaii Semi annual visual inspections required. Monitoring required annually for pollutants listed in Table 34.1 on p. 55 B 29 for Biochemical Oxygen Demand ( 5 day), Chemical Oxygen Demand, Total Suspended Solids, Total Phosphorus Total Nitrogen, Nitrate+ Nitrite Nitrogen, Oil and Grease, pH, toxic pollutants.  34 No effluent limitations or benchmarks used except for a range of pH.

Illinois Does not appear that any monitoring is required, but permit states that " the Agency may also require monitoring of any storm water discharge from any site to determine whether an individual permit is required."

Virginia The requirements and procedures for quarterly visual monitoring are applicable to all facilities covered under this permit, regardless of the facility's sector of industrial activity. There are four individual and separate categories of monitoring requirements and numeric effluent limitations that a facility may be subject to under this permit. The monitoring requirements and numeric limitations applicable to a facility depend on the types of industrial activities generating storm water runoff from the facility. Part IV of the permit ( 9 VAC 25 151 90 et seq.) identifies monitoring requirements applicable to specific sectors of industrial activity. The permittee must review Part I A 1 and Part IV of the permit to determine which monitoring requirements and numeric limitations apply to his facility. Unless otherwise specified, limitations and monitoring requirements under Part I A 1 and Part IV are additive. Sector specific monitoring requirements and limitations are applied discharge by discharge at facilities with colocated activities. Where storm water from the colocated activities are commingled, the monitoring requirements and limitations are additive. Where more than one numeric limitation for a specific parameter applies to a discharge, compliance with the more restrictive limitation is required. Where monitoring requirements for a monitoring period overlap ( e. g., need to monitor TSS one/ year for a limit and also one/ year for benchmark monitoring), the permittee may use a single sample to satisfy both monitoring requirements.

Table 70 1 identifies the specific industrial sectors subject to the benchmark monitoring requirements of this permit and the industry specific pollutants of concern. The permittee must refer to the tables found in the individual sectors in Part IV ( 9 VAC 25 151 90 et seq.) for benchmark monitoring cut off concentrations. Annual monitoring is required ( at least for the first two years).

Benchmark monitoring waivers are available for facilities testing below benchmark values. If samples were collected in two consecutive monitoring years, and the parameter concentrations were below the benchmark value in Part IV; and the facility is not subject to a numeric limitation for that parameter established in Part I A 1 c ( Coal Pile Runoff) or Part IV ( Sector Specific Permit Requirements), then sector specific benchmark monitoring is not required to be conducted in subsequent monitoring years.

Oregon Benchmark values are established ( and listed in Schedule A. 8.). All permittees must monitor for copper, lead, zinc, pH, total suspended solids, oil & grease, E. coli ( only for landfills, if septage and sewage biosolids are disposed at the site, and sewage treatment plants) twice per year and visually inspect once a month. The permittee is not required to conduct sampling if the benchmarks specified in Schedule A. 8 are met, or if the exceedance is due to natural or background conditions for at least four consecutive storm water monitoring events conducted by the permittee over 24 continuous months. Note that there is no reduction in monitoring allowed for facilities subject to limitations under CFR ( Schedule A. 7).

Pennsylvania Annual inspections required. Monitoring requirements and effluent limitations ( and BMPs) are assigned based on industry type ( in appendices). Monitoring required no less than annually and no more than once  35 per 6 months.

Rhode Island Monitoring requirements specific to industry type and established in Part 2. B. Sampling is required no more than annually and not less frequently than semi annually. No benchmarks are established.

Iowa Monitoring requirements specific per industry type.

Louisiana Permit outlines " universal monitoring requirements" in Part 5.1 and Part 6 outlines sector specific monitoring requirements. Quarterly visual monitoring is required for " universal" requirements. Certain sectors have benchmark values for certain parameters. Benchmark waivers are available to facilities whose discharges are below benchmark values. On both a parameter by parameter and outfall by outfall basis, you are not required to conduct sector specific benchmark monitoring required by the permit ( universal and sector specific) in the year 4 monitoring year provided: samples are collected for all four quarters of the year 2 monitoring year; and average concentration was below the benchmark value in Part 6; and a certification is included in the SWPPP that based on current potential pollutant sources and BMPs used, discharges from the facility are reasonably expected to be essentially the same ( or cleaner) compared to when the benchmark monitoring for the year 2 monitoring year was done.

Arkansas Facilities which are conducting quarterly biomonitoring testing will continue to biomonitor for Acute Whole Effluent Toxicity. Testing for Acute whole effluent will be deleted after the facility has passed two ( 2) consecutive testing periods, for both Daphnua pulex and Pimephales promelas ( fathead minnow). See Part VI. C. ( Page 41).

Other effluent monitoring requirements vary based on industry type and are found Part V. B.

Indiana Section 7.3 indicates that all dischargers ( identified in section 5( 4)) are to monitor annually for oil and grease, CBOD, COD, TSS, TKN, total phosphorus, pH, and nitrate+ nitrite. In addition , any facility discharge outfall subject to subdivision ( 1) to " shall be monitored for any pollutant attributable to a facility's industrial activity that is reasonably expected to be present in the discharge, as well as for any other pollutant that has the potential to be present in a storm water discharge as requested by the commissioner."

Maryland The permit states only that, " In the event that the Department identifies certain pollutants causing impairment of the receiving waters, the permittee may be required to amend the NOI by submission of storm water sampling data for the subject pollutants. The Department will provide further information, if applicable, after receipt of the NOI."

Michigan Monitoring plan submittal: Within six ( 6) months after the effective date of a certificate of coverage issued under this general permit, the permittee shall submit to the District Supervisor an approvable plan for monitoring and analysis of the storm water discharges authorized by the certificate of coverage and this  36 general permit. The plan shall include a proposed list of pollutants to be monitored to adequately characterize the discharge. At a minimum, the proposed list of pollutants shall include significant materials which are either stored in primary vessels within the permittee's secondary containment structure( s) or which the permittee knows or has reason to believe are present in an area other than a secondary containment structure, including a Site of Environmental Contamination or other activity which may contribute pollutants to the storm water for which the Department determines monitoring is needed. If the permittee has more than one special use area that would require storm water monitoring, such as a secondary containment structure and a Site of Environmental Contamination, then a separate monitoring plan shall be submitted for each special use area. The monitoring plan may include a request to monitor a combined discharge from multiple secondary containment structures if the permittee demonstrates in the plan that the monitoring is representative of water from all secondary containment structures. The plan( s) shall describe the monitoring frequency and duration, the total number of sampling events ( each discharge is one event), the monitoring and analysis methods to be used, and a date for submittal of the summarized analytical results. Samples shall be collected, preserved, handled, and analyzed using EPA approved methods ( see 40 CFR part 136) and quantification levels. Some desired quantification levels are available in Appendix A.

Monitoring secondary containment structures or retention basins with retention periods greater than 24 hours: Samples shall be collected from the water within a secondary containment structure or retention basin, or of the discharge prior to mixing with the receiving water or other waste streams. Grab samples may be taken unless the District Supervisor specifies other sampling methods. Pollutant concentrations and estimated total volume of the discharge shall be reported. Sampling may include visual observations to determine if the storm water contains unnatural turbidity, color, oil film, floating solids, foams, settleable solids, or suspended solids.

Monitoring storm water runoff from a Site of Environmental Contamination or other activity ( without secondary containment or 24 hour retention) which may contribute pollutants to the storm water for which the Department determines monitoring is needed: Samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inch of rainfall and causes a discharge; and at least 72 hours from the previous measurable ( greater than 0.1 inch) storm event. Quantitative data shall be reported for a grab sample taken during the first thirty minutes of the discharge. Additional samples shall be collected during a discharge event as necessary to be representative of the pollutants discharged from the site. Date and duration of the storm event, the rainfall measurement or estimate, duration between the storm event sampled and the end date of the previous measurable storm event, pollutant concentration( s), visual observations, and estimated total volume of the discharge shall be reported.

Monitoring startup: Upon completion and implementation of the Storm Water Pollution Prevention Plan ( Part I. A. 6.) and approval of the monitoring plan, the permittee shall begin monitoring the authorized discharge as specified in the plan. If the District Supervisor does not take action to approve or comment on the monitoring plan within ninety ( 90) days after submittal, and the Storm Water Pollution Prevention Plan is being implemented by the permittee in its entirety, the permittee shall begin storm water monitoring in accordance with the plan submitted. Nothing in this general permit shall prevent additional sampling, in addition to that specified in the monitoring plan, from being conducted. The analytical results of all representative discharge samples collected must be reported to the District Supervisor. If, upon review of the analysis, it is determined that any of the materials or constituents require limiting to protect the receiving waters in accordance with applicable Water Quality Standards, the Department may determine that an individual permit is needed for the discharge in accordance with Part I. A. 9. of this general permit.  37 Wyoming A minimum of semi annual monitoring is required of all timber products manufacturers; clay, concrete and gypsum products manufacturers; metal mining sites; scrap recycling and waste recycling facilities and auto salvage yards; and facilities with multiple industrial classifications. The parameters required vary with industrial classification. Visual examinations of the discharge are also required at the time of sampling. Permittees may request a reduction in sampling frequency when average results from storm water sampling are consistent and indicate that the discharges would not be expected to adversely impact surface waters of the state. The averaged results of at least four consecutive samples taken over a maximum of three consecutive years must be below the benchmark concentrations specified for the facility.

South Carolina Semi annual monitoring ( for industry specific parameters) is required for Section 313 of EPCRA Title III facilities; primary metal industries; land disposal units/ incinerators/ BIFs; wood treatment; coal pile runoff; and battery reclaimers.

B. 3. d.( vii) above. Value of receipts is a clear indication of whether a facility is engaged in these activities.

South Dakota Sampling and testing of storm water for specific parameters is not required on a routine basis under this permit ( with the exception of coal pile runoff). The Secretary reserves the right to require sampling and testing, on a case by case basis, in the event that there is reason to suspect that compliance with the pollution prevention plan is a problem, or to measure the effectiveness of the BMPs in removing pollutants in the effluent.  38 Texas Annual monitoring is required of all facilities ( unless qualify for a hazardous metals waiver) to determine compliance with daily maximum metals effluent limitations for inland or tidal waterways. In addition, benchmark monitoring is required for specific sectors ( Part IV). Benchmark monitoring must be conducted on a quarterly basis for two consecutive periods during the term of the permit. A waiver from benchmark monitoring may be obtained for the Second Period based on average results of the First Period. Waivers are allowable on a parameter by parameter basis and on an outfall by outfall basis. To qualify for a waiver for a specific pollutant at a specific outfall during the Second Period, the following conditions must be met: ( a) a minimum of one sample is collected from the outfall, and analyzed for the specific pollutant, during each quarter of the First Period; and ( b) the average of the four results for that pollutant is less than the benchmark value; ( c) the current and projected potential pollutant sources of the particular benchmark parameter are not expected to significantly increase.

Mississippi Monitoring shall be required if: 1. the waterbody has a wasteload allocation for a specific parameter( s) established by a TMDL; and 2. MDEQ has reason to believe the specific parameter( s) is present at the facility. Monitoring is required so that appropriate changes to the existing SWPPP may be affected so that storm water discharges will not adversely impact impaired waters. If requested, sampling shall be conducted at least quarterly and according to Part IV. F & G. Additional specific monitoring requirements for SARA Title III, Section 313 facilities as well as facilities with coal piles. No other monitoring required.

Montana Part III. A. 2. identifies the facilities required to monitor and the parameters required at least semi annually. Frequency may be re evaluated by the Department after a minimum of three monitoring periods of representative sample data have been collected. The Department may suspend the sampling requirement if after any three monitoring periods ( representative sampling events), a facility can demonstrate the following conditions: a. BMP implementation is satisfactorily reducing and minimizing the potential discharge of pollutants in storm water. b. The storm water sampling test results for the parameters tested for under Part III. of this Permit have not exceeded the U. S. EPA benchmark values, which have been adopted by the Department, as presented in Attachment B entitled " Storm Water Discharge Guidelines, December 1, 2000." c. Storm water discharges have not resulted in being unable to attain a Total Maximum Daily Load ( TMDL) or Wasteload Allocation which has been developed and approved by the Department for the receiving surface waters. d. There have been no violations of the conditions and requirements in the permit. e. There are no significant site characteristics, concerns, or problems ( such as spills or releases) which could potentially allow pollutants to come into contact with storm water.

Nebraska No routine monitoring is required unless requested specifically by the state for a facility.

Nevada Quarterly visual monitoring is required of all facilities.

The following categories of facilities have storm water effluent guidelines for at least one of their  39 subcategories: cement manufacturing ( 40 CFR 411); feedlots ( 40 CFR 412); fertilizer manufacturing ( 40 CFR 418); petroleum refining ( 40 CFR 419); phosphate manufacturing ( 40 CFR 422); steam electric power generation ( 40 CFR 423); coal mining ( 40 CFR 434); mineral mining and processing ( 40 CFR 436); ore mining and dressing ( 40 CFR 440); paving and roofing materials ( 40 CFR 443); and landfills ( 40 CFR 445). A facility that falls into one of these general categories shall examine the applicable effluent guideline to determine if it is categorized in one of the subcategories that have storm water effluent guidelines. If a facility is classified as one of those subcategories, that facility is subject to the standards listed in the CFR for that category, must sample storm water discharges from the facility, at a minimum, of once per calendar year.

New York Semi annual monitoring is required for Section 313 of SARA Title III facilities; primary metals facilities; land disposal units/ incinerators/ BIFs; wood treatment facilities; coal pile runoff facilities; battery reclaimer facilities.

Ohio Part V contains numeric effluent limitations for coal pile runoff, monitoring requirements for storm water runoff from 11 industrial categories ( defined in Attachment IV), and additional storm water monitoring requirements for facilities required to report under SARA Title III for " Section 313 Water Priority Chemicals." Effluent limitations of 50 mg/ l for Total Suspended Solids and a pH range of 6.0 S. U. to 9.0 S. U. apply to coal pile runoff. All facilities required to monitor storm water discharges must monitor for: oil & grease, pH, storm event duration, amount of precipitation, time between storm events, and volume of discharge. There are other parameters where monitoring may be required dependent upon industrial category and whether a discharger is a " Section 313" facility ( see Attachment IV for detailed requirements that must be met).

Oklahoma All facilities, without exception, will be subject to quarterly visual monitoring. Facilities with effluent limitation guidelines also are required to monitor for compliance ( facilities listed in Table 1 3 of Part 1.3). Sector specific monitoring requirements and limitations are applied discharge by discharge at facilities  40 ( identified in Part 12) with co located activities. Where storm water from the co located activities are comingled, the monitoring requirements and limitations are additive. Where more than one numeric limitation for a specific parameter applies to a discharge, compliance with the more restrictive limitation is required.

Vermont ( 7. Monitoring Requirements) The monitoring requirements and numeric limitations applicable to a facility depend on a number of factors, including but not limited to the types of industrial activities generating storm water runoff from the facility. The requirements and procedures for quarterly visual monitoring are applicable to all facilities covered under this permit, regardless of the facility's sector of industrial activity. Attachment A identifies the industrial sectors subject to the Analytical Benchmark Monitoring requirements of this permit and the industry specific pollutants of concern. Attachment B identifies the applicable monitoring requirements and Benchmark Monitoring cut off concentrations for each specific sector identified in Attachment A. The permittee must review these attachments to determine which monitoring requirements and numeric limitations apply to the facility. Unless otherwise indicated, limitations and monitoring requirements are additive and the more restrictive limitation applies. Benchmark monitoring must occur quarterly in the 2nd and 4th years of the permit. On both a parameter by parameter and outfallby outfall basis, the permittee is not required to conduct sector specific benchmark monitoring in the second monitoring period provided that: samples were collected for all four quarters of the first monitoring period and the average pollutant concentration was below the benchmark value; the discharge is not subject to a numeric limitation for that parameter; and the permittee includes a certification in the SWPPP that based on current potential pollutant sources and BMPs used, discharges from the facility are reasonably expected to be essentially the same ( or cleaner) compared to when the benchmark monitoring for the first monitoring period was done.

North Carolina NCG130000 Non metal Waste Recycling Industry Semi annual visual inspection of discharge required of all permittees. Facilities which have any vehicle maintenance activity occurring on site which uses more than 55 gallons of new motor oil per month when averaged over the calendar year shall perform analytical monitoring as specified in Table 2. This monitoring shall be performed at all outfalls which discharge storm water runoff from the vehicle maintenance areas. For each parameter, the arithmetic mean of all analytical sampling results collected during the coverage of the permit shall be calculated for each individual outfall. The computed arithmetic mean is then compared to the cut off concentrations listed in Table 3 ( page 5). If the arithmetic mean is less than the specified cut off concentration for a parameter other than pH or within the specified range for pH only, then the facility is not required to continue annual analytical monitoring for that parameter ( at that outfall) during the remaining coverage of the permit unless a significant change in facility operations or configuration occurs. If a cut off concentration results in discontinued analytical monitoring at an individual discharge outfall, the permittee is required to maintain facility operations that ensure the continuation of storm water runoff quality. The permittee must perform analytical sampling during the first year that the facility becomes subject to this Section C and last year of permit coverage regardless of cut off concentration conditions. Analytical results from sampling during the final year of permit coverage must be submitted with the permit renewal application. All analytical monitoring shall be performed during a representative storm event.

NCG080000 Vehicle Maintenance Areas Analytical annual monitoring of storm water discharges shall be performed as specified in Table 1, for those facilities conducting vehicle maintenance activities and utilizing more than 55 gallons new motor oil per month when averaged over the year ( those vehicle maintenance activities not utilizing more than 55 gallons of new motor oil per month are not required to conduct analytical monitoring). For each parameter, the arithmetic mean of all analytical sampling results collected during the coverage of the permit shall be calculated for each individual outfall. The computed arithmetic mean is then compared to the cut off concentrations listed below in Table 2. If the arithmetic mean is less than the specified cut off concentration for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter ( at that outfall) during the remaining coverage of the permit unless a significant change in facility operations or configuration occurs. If a cut off concentration results in discontinued analytical monitoring at an individual discharge outfall, the permittee is required to maintain facility operations that ensure the continuation of storm water runoff quality. The permittee must perform analytical sampling during the first and last year of the permit coverage regardless of cut off concentration conditions. Analytical results from sampling during the final year of the permit coverage must be submitted with the permit renewal application. All analytical monitoring shall be performed during a representative storm event. In addition, monitoring is required for discharge from oil water separators and bulk terminals. Semi annual visual inspections are also required of all discharges.

NCG140000 Ready Mix Concrete All facilities must monitor for the parameters listed in Table 1. Facilities which have any vehicle maintenance activity occurring on site which uses more than 55 gallons of new motor oil per month when averaged over the calendar year shall perform analytical monitoring as specified below in Table 3. This monitoring shall be performed at all outfalls which discharge storm water runoff from the vehicle maintenance areas.  44 For each parameter, the arithmetic mean of all annual analytical sampling results collected during the term of the permit shall be calculated for each individual outfall. The computed arithmetic mean is then compared to the cut off concentrations listed in the permit. If the arithmetic mean is less than the specified cut off concentration for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter ( at that outfall) during the remaining term of the permit unless a significant change in facility operations or configuration occurs. If a cut off concentration results in discontinued analytical monitoring at an individual discharge outfall, the permittee is required to maintain facility operations that ensure the continuation of storm water runoff quality. The permittee must perform analytical sampling of storm water discharges during the first and last year of the permit coverage regardless of cut off concentration conditions. Analytical results from sampling during the final year of the permit coverage must be submitted with the permit renewal application. All analytical monitoring shall be performed during a representative storm event.

Section C contains the annual monitoring requirements and effluent limitations for the discharge of process wastewater associated with four distinct activities: 1) Vehicle and equipment cleaning  external surfaces; 2) Overflow from recycle systems that receive storm water runoff; 3) Wetting of raw material stockpiles; 4) Mixing drum cleaning. Discharge of process wastewater generated by any other activity is not authorized under this permit. In the event that authorized process wastewaters commingle prior to discharge, sampling the combined discharge will meet the conditions of this permit for those separate activities, with respect to the annual sample. In the case of commingled process wastewater, the most stringent of the applicable limits will apply.

Semi annual visual inspections of all discharge outfalls are required as well.

Wisconsin All permittees required to do dry weather outfall inspections to determine if there is a discharge of nonstrorm water during the 1st year of the permit. In addition each facility must perform a quarterly visual inspection of all outfalls.

Heavy Manufacturers Required to annually monitor for all pollutants identified in the SWPPP as " residual pollutants". After review of the facility monitoring plan portion of the SWPPP, the department shall add additional pollutants to the monitoring list if it has cause to do so based on a reasonable probability that the pollutants will be present in storm water discharges from the facility. The department shall remove pollutants from the monitoring list if it determines that continued monitoring for the pollutant serves no further purpose. Chemical monitoring may be discontinued after submitting the second round of chemical monitoring results to the department with the annual facility site compliance inspection report unless the department directs the permittee otherwise. The department shall require additional chemical sampling within a tier 1 general permit for industrial facilities where chemical monitoring has shown a reasonable potential that the storm water discharge from an individual facility or a type of industry will exceed a water quality standard.

New Jersey Basic Industrial Storm Water General Permit ( NJ0088315 ( 5G2)) No monitoring requirements are included or incorporated by reference.

Tennessee Monitoring requirements are specific to industries and are outlined in Part XI ( pps. 57 338).  45 Water Quality Issues Discharges to impaired waters Washington Monitoring: In addition to regular monitoring, beginning with the second quarter of the year 2003, all facilities that discharge to waters listed as impaired by the State under Section 303( d) of the Clean Water Act ( except for sediment or tissue) must conduct quarterly monitoring of authorized discharges of storm water to surface water. Samples must be analyzed for the parameters named on the 303( d) as causing impairment of the listed waters except for temperature which is not required and fecal coliform which is only required if there is a potential source from the industrial activity. Discharges to a waterbody for which a TMDL has been completed must be consistent with the TMDL determination. Where the TMDL determination sets load allocations for new discharges or limits pollutant concentrations in the discharge, the permittee must conduct monitoring for the named pollutant( s) and the monitoring must be consistent with TMDL requirements, if any. Permittees may suspend monitoring for a listed parameter if: ( 1) eight consecutive quarterly samples fail to detect the presence of the listed parameter. Fail to detect does not apply to pH. For pH it is eight consecutive quarters where the values are not outside of the water qualitybased range of 6.5 to 8.5 ( freshwater) or 7.0 to 8.5 ( marine), or ( 2) subject to State approval, the permittee can demonstrate after eight or more consecutive quarterly samples that there is no reasonable potential to violate water quality standards ( does not state how to determine reasonable potential). In addition to the requirements above, beginning with the second quarter of the year 2003, all facilities that discharge to waters listed by the State for violations of sediment standards under Section 303( d) of the Clean Water Act must conduct quarterly monitoring of authorized discharges of storm water to surface water for total suspended solids ( TSS). Discharges that demonstrate TSS levels consistent with secondary treatment standards ( 30 mg/ L monthly average not to exceed 45 mg/ L) are considered unlikely to violate sediment quality standards. Permittees that can demonstrate consistent attainment TSS levels of secondary treatment standards may suspend monitoring for the duration of the permit term. Consistent attainment is defined as 8 consecutive quarterly samples ( omitting any quarter where there is no discharge) with an average TSS of 30 mg/ L and no sample exceeding 45 mg/ L. Discharge Limitations: A permittee's discharge must not cause or contribute to an excursion of the State's water quality standards, including the State's narrative criteria for water quality. For 303( d) listings based on numeric water quality criteria ( except for sediment or tissue), permittees must comply with the State's water quality standard for each pollutant named as a pollutant causing a violation of water quality standards at the location named on the State's 303( d) list ( except for temperature which is not required and fecal coliform which is only required if there is a potential source from the industrial activity). The State will not require monitoring for fecal coliform if the permittee can document that there is no potential source of fecal coliform from any of their industrial activities. Permittees must be in compliance with any applicable TMDL determination. New facilities that discharge either directly or indirectly via a storm water conveyance system to waters listed as impaired by the State under Section 303( d) of the Clean Water Act must comply with the State's water quality standards for the named pollutant( s) at the point of discharge. Facilities with coverage under this permit, that implement a significant process change must either comply with the State's water quality standards for the named pollutant( s) at the point of discharge or demonstrate no increase in loading from the entire facility as a result of the process change. All new discharges must be in compliance with any applicable TMDL determination. Existing facilities that discharge either directly or indirectly via a storm water conveyance system to waters listed as impaired by the State under Section 303( d) of the Clean Water Act must comply with the State's water quality standards for the named pollutant( s) at the point of discharge. Existing  46 facilities subject to a TMDL determination must be in compliance with the conditions of the TMDL determination and detailed implementation plan. If a permittee discharging to waters listed under 303( d) fails to comply with these effluent limits, a compliance schedule ( page 19 of the permit) immediately becomes applicable and is considered to be the applicable interim effluent limitations until compliance with water quality standards is achieved or a TMDL is completed. Eight consecutive samples that do not exceed the applicable water quality standard for the listed pollutant( s) will demonstrate compliance with water quality standards and allow the Permittee to exit the compliance schedule. When a TMDL is completed, the Permittee must comply with the TMDL determination.

West Virginia Permittees discharging pollutants of concern to waters for which there is a TMDL established or approved by EPA are not eligible for coverage under this general permit, unless the permit conditions of this general permit are consistent with the assumptions and requirements of such TMDL. Therefore, the permittee must submit an NPDES application to West Virginia Department of Environmental Protection for coverage under an individual NPDES permit. The permittee should consult with the State or EPA TMDL authority to confirm if his/ her facility is subject to an approved TMDL.

California No reference to TMDLs or 303( d) listed waterbodies are included in the permit.

Connecticut No reference to TMDLs or 303( d) listed waterbodies are included in the permit.

Georgia Storm water discharges associated with industrial activity to waters of the State for which a Total Maximum Daily Load ( TMDL) has been approved, are not authorized by the general permit unless the facility develops and implements a Storm Water Pollution Prevention Plan ( SWP3) that is consistent with the TMDL. ( Reviewer Note: exact permit text pp. 10  13)

For stream segments with approved TMDLs ( this section does not apply to stream segments listed for fecal coliform, which will be addressed on a case by case basis). An operator is not eligible for coverage under this permit for discharges of storm water associated with industrial activity to waters of the State for which a TMDL is approved prior to or during the term of this permit, unless the facility develops, implements, and maintains a SWP3 that is consistent with the TMDL. The SWP3 must specifically address any conditions or requirements included in the TMDL that are applicable to the operator's discharge within the timeframe specified in the TMDL. If the TMDL establishes a specific numeric wasteload allocation that applies to an operator's discharge, or to storm water discharges associated with industrial activity in general, then the operator must incorporate that allocation into the facility's SWP3 and implement all necessary measures to meet that allocation.

For all 303( d) listed stream segments ( with or without approved TMDLs). This section does not apply to stream segments listed for fecal coliform, which will be addressed on a case by case basis. a. Any operator who intends to obtain coverage under this permit for all storm water discharges associated with industrial activity to, or within one ( 1) linear mile upstream of and within the same watershed as, any portion of an impaired stream segment listed as " partially supporting" or " not supporting" designated uses on Georgia's most current 303( d) list must satisfy the requirements of Part III. C of this permit if the pollutant( s) of concern for which the impaired stream segment has been listed may be exposed to storm  47 water as a result of current or previous industrial activity at the facility. Those discharges that are within one ( 1) linear mile of an impaired stream segment, but are not located within the watershed of any portion of that stream segment are excluded from this requirement. Georgia's 303( d) list can be viewed on EPD's website at www. dnr. state. ga. us/ dnr/ environ.

Regulated industrial facilities that are subject to the requirements in Part III. C. of this permit must conduct storm water discharge sampling for the pollutant( s) of concern on a monthly basis for a period of twentyfour ( 24) months. The sampling will only be required for those outfalls at the facility that have the potential to discharge the pollutant( s) of concern. The sampling must be conducted in accordance with Parts VI. A. 3, 4, and 5 of this permit, except that composite samples may be collected in lieu of grab samples at the permittee's discretion. The Director may require composite sampling on a case by case basis in order to ensure that representative samples are collected.

Facilities discharging to a 303( d) listed stream segment, as described above, for which the listing criterion is identified as " biota, toxicity, FCG ( fish consumption guidelines) or TWR ( trophic weighted residue value of mercury in fish tissue)" will only be required to conduct sampling under Part III. C if a TMDL identifying a specific water quality parameter has been approved for the stream segment. Facilities discharging to a 303( d) listed stream segment, as described above, for which the listing criterion is identified as " sediment" are required to sample for Total Suspended Solids ( TSS). Facilities discharging to a 303( d) listed stream segment, as described above, for which the listing criterion is identified as " Dissolved Oxygen or ( DO)" will only be required to conduct sampling under Part III. C if organic material may be exposed to storm water as a result of current or previous industrial activity at the facility. These facilities must sample for Five Day Biochemical Oxygen Demand ( BOD5) and Dissolved Oxygen ( DO).

All facilities subject to the sampling requirements under Part III. C. of this permit must begin conducting the sampling no later than ninety ( 90) days after the effective date of the permit or no later than ninety ( 90) days after the facility becomes subject to the sampling requirements of Part III. C. A report must be submitted to EPD's Water Protection Branch summarizing the results of the sampling on a semi annual basis. The report should also include a narrative description of any recent or planned improvements to the permittee's SWP3. Within 90 days after the end of the sampling program, the permittee must submit a summary report evaluating the overall results of the sampling program.

b. Facilities with storm water discharges associated with industrial activity that have been found by the facility's own sampling, or through sampling by EPD, to exceed Georgia's Instream Water Quality Standards ( Georgia Rule 391 3 6. 03) or the applicable parameter benchmark values for the pollutant( s) of concern in more than twenty five ( 25) percent of the storm water discharge samples collected during the sampling program must apply for an individual NPDES permit or develop and implement a Supplemental Best Management Practices ( BMP) Program within nine ( 9) months after the sampling program has ended, unless the permittee can provide a written justification, along with the summary report, explaining why the facility's storm water discharges associated with industrial activity do not have a reasonable potential to cause or contribute to an instream water quality violation. EPD will consider the written justification prior to requiring additional measures from the facility. The storm water parameter benchmark values for BOD5 and Total Suspended Solids ( TSS) are 30 mg/ l and 100 mg/ l, respectively. These storm water parameter benchmark values will be interpreted to be the instream water quality standards for these parameters for the purposes of monitoring under Part III. C of this permit.  48 c. Those facilities electing to develop a Supplemental BMP Program in lieu of applying for an individual NPDES permit must submit a copy of the Supplemental BMP Program to EPD prior to implementation. The Supplemental BMP Program must specifically address the storm water discharge( s) that have a reasonable potential to cause or contribute to an instream water quality standards violation and establish appropriate BMPs designed to prevent such exceedences in them storm water discharge( s) to the impaired stream segment. To evaluate the effectiveness of the Supplemental BMP Program, a minimum of twelve ( 12) additional samples must be collected over a twelve month period at appropriate storm water outfall locations, and analyzed for the impaired segment pollutant( s) of concern, beginning within nine ( 9) months after the twenty four ( 24) month sampling program has ended. The sampling must be conducted in accordance with Parts VI. A. 3, 4, and 5 of this permit, except that composite samples may be collected in lieu of grab samples at the permittee's discretion. The Director may require composite sampling on a caseby case basis in order to ensure that representative samples are collected. A report must be submitted to EPD's Water Protection Branch summarizing the results of the sampling on a semiannual basis. The report should also include a narrative description of any recent or planned improvements to the permittee's SWP3. If the sampling results show that the Supplemental BMP Program has not reduced the pollutant( s) of concern to levels below the Instream Water Quality Standards or the applicable parameter benchmark values ( for BOD5 or TSS) in at least seventy five ( 75) percent of the samples collected during this twelve ( 12) month period, then the facility must apply for an individual NPDES permit no later than six ( 6) months after the twelve ( 12) month sampling program has ended, unless the permittee can provide a written justification, along with the summary report, explaining why the facility's storm water discharges associated with industrial activity do not have a reasonable potential to cause or contribute to an instream water quality violation. EPD will consider the written justification prior to requiring additional measures from the facility. ( Reviewer Note: A table is included in the permit outlining the timeline for doing the above sampling, reporting and application process on page 13.)

Hawaii No reference to TMDLs or 303( d) listed waterbodies are included in the permit.

Illinois Existing dischargers, new dischargers and new sources which discharge to a water body that is impaired and has an approved TMDL are required to carefully document the justifications for all BMP selections in a SWPPP, and install, implement and maintain BMPs that are consistent with all relevant TMDL allocations and with all relevant conditions in an implementation plan. For any site which discharges directly to an impaired water identified in the Agency's 303( d) listing, and if any parameter in the subject discharge has been identified as the cause of impairment, the storm water pollution prevention plan for that site shall be designed for a storm event equal to or greater than a 25 year 24 hour rainfall event. If required by federal regulations, the storm water pollution prevention plan shall adhere to a more restrictive design criteria.

Virginia The following storm water discharges associated with industrial activity are not authorized by this permit: Discharges to waters for which a " total maximum daily load" ( TMDL) allocation has been established by the board and approved by EPA unless the storm water pollution prevention plan ( SWPPP) developed by the owner incorporates measures and controls that are consistent with the assumptions and requirements of such TMDL. The SWPPP must incorporate any conditions applicable to discharges from the facility that are necessary for consistency with the assumptions and requirements of the TMDL. If a specific numeric  49 wasteload allocation has been established that would apply to discharges from the facility, the owner must incorporate that allocation into the SWPPP and implement necessary steps to meet that allocation.

Oregon Oregon Administrative Rule 340 041 0026( 3)( a)( D), Surface Water Temperature Management Plan . Individual storm water discharges are not expected to cause a measurable increase in stream temperature because the storm water discharges mainly occur at a time of year when ambient stream and runoff temperatures are relatively low. Compliance with this permit meets the requirement of OAR 340 041 0026( 3)( a)( D) to develop and implement a surface water temperature management plan. If permitted storm water discharges in a particular basin are assigned waste load allocations under a Total Maximum Daily Load for temperature, then permittees in this basin will be required to implement additional management practices to reduce the temperature of the discharges. These practices include, but are not limited to, increased vegetation to provide for shading, underground conveyance systems or detention vaults, and filter treatment systems to reduce detention times. If Total Maximum Daily Loads ( for pollutants other than temperature) are established and the discharge from a permitted source is assigned a waste load allocation, application for an individual or different general permit or other appropriate tools may be required to address the allocation.

Texas Coverage is allowed under the general permit if the executive director has not determined that continued coverage under an individual permit is required based on consideration of a TMDL model, anti backsliding policy, history of substantive noncompliance or other TAC 205 considerations and requirements, or other sites pecific considerations. New sources or new discharges of the constituent( s) of concern to impaired waters are not authorized by this permit unless otherwise allowable under 30 TAC, Chapter 305 and applicable state law. Impaired waters are those that do not meet applicable water quality standard( s) and are listed on the Clean Water Act Section 303( d) list. Constituents of concern are those for which the water body is listed as impaired. Discharges of the constituent( s) of concern to impaired water bodies for which there is a TMDL implementation plan are not eligible for this permit unless they are consistent with the approved TMDL and the implementation plan. Permitted facilities must incorporate the limitations, conditions and requirements applicable to their discharges, including monitoring frequency and reporting required by TNRCC rules, into their SWP3 in order to be eligible for permit coverage. For discharges not eligible for coverage under this permit, the discharger must apply for and receive an individual or other applicable general TPDES permit prior to discharging.

Storm Water Pollution Prevention Plan Requirements Washington Washington State has specific guidance manuals for BMPs required. State may require additional BMPs based on the current state guidance manuals where the permittee exceeds benchmark values for required sampling. The permit requires the permittee to conduct visual monitoring and the monitoring may identify BMPs that are inadequate or pollutant sources that are not identified or poorly described in the SWPPP. When visual monitoring identifies inadequacies in the SWPPP, due to the actual discharge of or potential to discharge a significant amount of any pollutant, the SWPPP must be modified and BMPs adjusted to correct the deficiency. ( Reviewer Note: Detailed requirements described on pp. 35  42). SWPPP contents are standard requirements.

West Virginia  69 ( Reviewer Note: Requirements detailed on page 28  31.) Each facility covered by this permit shall have a storm water pollution plan and a groundwater protection plan. These two plans may be combined into one plan so long as all requirements for both plans are met. Alternatively, they may be developed and maintained as separate stand alone documents. SWPPP contents are standard requirements.

California SWPPP contents are standard requirements.

Connecticut Contents of the SWPPP are standard requirements except the following: ( G) Additional Requirements for Salt Storage: The Plan shall provide that storage piles of salt ( including pure salt or salt mixed with other materials) used for deicing or other commercial or industrial purposes and which generate a storm water discharge associated with industrial activity that is discharged to waters of the state, shall be enclosed or covered by structural means. In areas with a groundwater classification of GA or GAA, an impervious liner shall be utilized under the pile to prevent infiltration to groundwater. In addition, on or after October 1, 1995 no new road salt storage facilities shall be located within a 100 year floodplain as defined and mapped for each municipality under 44 CFR 59 et seq. or within 250 feet of a well utilized for potable drinking water supply or within a Level A aquifer protection area as defined by mapping pursuant to Section 22a 354c of the General Statutes. ( H) Future Construction: The permittee shall ensure that oil and sediment control structures or other devices are used within the drainage system for all construction that ( i) may impact the drainage system and ( ii) occurs on site on or after the effective date of this general permit. The Plan must state that a goal of 80 percent removal of total suspended solids from the storm water discharge shall be used in designing and installing storm water management measures. Note that any construction activity that disturbs greater than five acres must be registered and conducted in accordance with the General Permit for the Discharge of Storm water and Dewatering Wastewaters from Construction Activities. However, all construction activities, regardless of size, shall comply with the Connecticut Guidelines for Soil Erosion and Sediment Control ( DEP Bulletin 34). In addition, the permittee shall avoid, wherever possible, the use of copper or galvanized roofing or building materials for any new construction where these materials will be exposed to storm water.
