Title of Regulation: 9VAC25-190. Virginia Pollutant Discharge Elimination System (VPDES) General Permit Regulation for Nonmetallic Mineral Mining (amending 9VAC25-190-10, 9VAC25-190-15, 9VAC25-190-20, 9VAC25-190-50, 9VAC25-190-60, 9VAC25-190-70).
The Virginia Pollutant Discharge Elimination System (VPDES) General Permit Regulation for Nonmetallic Mineral Mining has existed since 1994. This general permit contains effluent limitations, monitoring requirements, and special conditions for discharges of process wastewater, which may be commingled with stormwater, and stormwater associated with industrial activity to surface waters. The amendments to the regulation are being made to reissue this general permit.
• Remove monitoring for total petroleum hydrocarbons for outfalls that contain process wastewater from vehicle or equipment degreasing activities based on low levels in reported data;
• Require the registration statement safety data sheet information and dosing rate treatment chemicals added to wastewater or stormwater that could be discharged;
• Add a new provision that restricts permit coverage for the use of cationic flocculants unless approved by the department based on a demonstration of no aquatic toxicity;
• Remove the special condition addressing special water quality standards in the Chickahominy watershed based on revisions to the applicability of those standards;
• Add best management practices requirements for blasting;
• Add a list of authorized nonstormwater discharges;
• Merge the comprehensive site compliance evaluation with the routine inspection provisions;
• Waive routine facility inspection requirements for Virginia Environmental Excellence Program E3 and E4 facilities; and
• Require applicants submit their state corporation entity identification number if the facility is required to obtain an entity identification number.
The substantive changes since the proposed stage require a demonstration of no aquatic toxicity for all added chemicals that could be discharged with the registration statement and require training at active mining sites and at temporarily inactive sites that are staffed.
"Best management practices" or "BMPs" means schedules of activities, practices (and prohibitions of practices), structures, vegetation, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants to surface waters. BMPs also include treatment requirements, operating procedures, and practices to control plant site [ run-off runoff ], spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
[ "Inactive mining operations" means mining sites that are not being actively mined, but which have an identifiable owner or operator; inactive mining sites do not include sites where mining claims are being maintained prior to disturbances associated with the extraction, beneficiation, or processing of mined materials, nor sites where minimal activities are undertaken for the sole purpose of maintaining a mining claim. ]
[ (Inactive mining operations are mining sites that are not being actively mined, but which have an identifiable ] owner/operator [ owner or operator; inactive mining sites do not include sites where mining claims are being maintained prior to disturbances associated with the extraction, beneficiation, or processing of mined materials, nor sites where minimal activities are undertaken for the sole purpose of maintaining a mining claim.) ] Industrial activity also includes facilities classified under other SIC codes that may be colocated within the mineral mine permit area, unless they are expressly excluded by this general permit.
"[ Run-off Runoff ] coefficient" means the fraction of total rainfall that will appear at the conveyance as [ run-off runoff ].
"Significant materials" includes, but is not limited to, raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials; hazardous substances designated under [ Section § ] 101(14) of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 USC § 9601 et seq.); any chemical the owner is required to report pursuant to [ Section § ] 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) (42 USC § 11001 et seq.); fertilizers; pesticides; and waste products such as ashes, slag and sludge (including pond sediments) that have the potential to be released with stormwater discharges.
"Stormwater" means stormwater [ run-off runoff ], snow melt [ run-off runoff ], and surface [ run-off runoff ] and drainage.
[ "Temporarily inactive mineral mining facility" means a site or portion of a site where nonmetallic mineral mining or milling occurred in the past but currently is not being actively undertaken, and the facility is covered by an active mining permit issued by the applicable state or federal agency. ]

e. SIC Code 1442 - NAICS Code [ 212421 212321 ],
2. Facility name, county, [ and ] location [ , latitude, and longitude ];
8. List of any treatment chemicals added to water wastewater or stormwater that could be discharged. Include safety data sheets [ and, ] the maximum proposed dosing rates [ , and a demonstration that application or use will not result in aquatic toxicity ];
15. Whether the permitted [ outfall facility ] will discharge to a municipal separate storm sewer system (MS4). If so, provide the name of the MS4 owner. The yes, the facility owner of the facility shall notify the MS4 owner in writing of the existence of the discharge within 30 days of coverage under the general permit and shall copy the DEQ regional office with the notification at the time of registration under this permit and include that notification with the registration statement. The notification shall include the following information: the name of the facility, a contact person and phone number contact information, the location of the discharge, the nature of the discharge, and the facility's VPDES general permit number [ if assigned by DEQ ];
18. [ For applicants other than a sole proprietor, the ] State Corporation Commission entity identification number [ if the facility is required to obtain an entity identification number by law ]; and
(2)Estimate of the total volume of the discharge during the storm event.
(3)Refer to Part I B 12 should the TSS evaluation monitoring exceed 100 mg/l daily maximum.Permittees shall review the results of the TSS monitoring required by Part I A 2 a to determine if changes to the stormwater pollution prevention plan (SWPPP) may be necessary. If the TSS monitoring results are greater than the evaluation value of 100 mg/l, then the permittee shall perform [ the ]a routine facility inspection within five days of becoming aware of the exceedance and maintain documentation as described in Part II H 3 d for that outfall. Any deficiencies noted during the inspection shall be corrected within 60 days of being identified.
b. The permittee shall conduct calendar quarterly visual monitoring of stormwater discharges associated with industrial activity. The monitoring shall include examination of stormwater samples representative of storm event discharges from the facility and observation of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution. Documentation of visual monitoring of stormwater shall be maintained onsite in the SWPPP and include the examination date and time, examination personnel, outfall location, the nature of the discharge [ (i.e., runoff or snowmelt) ], visual quality of the stormwater discharge and probable sources of any observed stormwater contamination. Part II A regarding monitoring instructions, Part II B regarding representative outfalls, and Part II C regarding sampling waivers shall apply to the taking of samples for visual monitoring except that the documentation required by these sections shall be retained with the SWPPP [ visual monitoring records ] rather than submitted to the department. Calendar quarters equal the following three-month periods each year of permit coverage: January through March, April through June, July through September, and October through December.
3. There shall be no chemicals added to the discharge, other than those listed on the owner's approved registration statement, unless prior approval of the chemical is granted by the board. [ The use of cationic chemicals is ineligible for coverage under this permit unless such use is approved by the board based on a demonstration that the application or use will not result in aquatic toxicity. ]
8. Process water may be used on site for the purpose of dust suppression. Dust suppression shall be carried out as a best management practice but not as a wastewater disposal method provided that ponding or direct [ run-off runoff ] from the site does not occur during or immediately following its application. Dust suppression shall not occur during a storm event that results in an actual discharge from the site.
b. Solids deposition to surface water as a result of [ a discharge associated with ] industrial activity; or
16. 14. Inactive and unstaffed facilities (including temporarily inactive [ sites) and unstaffed facilities) ].
(3) All discharges associated with this facility have been covered by [ an a ] VPDES individual VPDES permit or an alternative VPDES permit; or
(c) A statement indicating that all discharges have been covered by [ an a ] VPDES individual VPDES permit; or
B. Representative discharge outfalls. When a If a facility has two or more exclusively stormwater outfalls that the permittee reasonably believes discharge substantially identical effluents, based on a consideration of similarity of industrial activity, significant materials, [ size of the drainage areas, ] frequency of discharges, and management practices and activities within the area drained by the outfalls, then the permittee may submit information with the registration statement substantiating the request for only one DMR to be issued for the outfall to be sampled that represents one or more substantially identical outfalls. Also the The permittee must shall document representative outfalls in the SWPPP and list on the DMR of the outfall to be sampled all outfall locations that are represented by the discharge. The representative outfall monitoring provisions apply to Part I A 2 a monitoring and quarterly visual monitoring.
1. The locations of the outfalls; [ and ]
2. An evaluation, including available monitoring data, indicating why the outfalls are expected to discharge substantially identical effluents [ ; and
3. An estimate of the size of the drainage area in acres ].
a. Good housekeeping. Good housekeeping requires the clean and orderly maintenance of areas that may contribute pollutants to stormwater discharges in a clean, orderly manner. The plan SWPPP shall describe procedures performed to minimize contact of materials with stormwater [ run-off runoff ]. Particular attention should be paid to areas where raw materials are stockpiled, material handling areas, storage areas, liquid storage tanks, vehicle fueling and maintenance areas, and loading/unloading loading or unloading areas, and vehicle entrance and exits. The permittee shall keep clean all exposed areas of the facility that are potential sources of pollutants in stormwater. The permittee shall sweep or vacuum paved surfaces of the site that are exposed to stormwater at regular intervals or use other equivalent measures to minimize the potential discharge of these materials in stormwater. Indicate in the SWPPP the frequency of sweeping, vacuuming, or other equivalent measures.
e. Employee training. Employee training shall be conducted at least annually at active mining [ sites ] and [ at those ] temporarily inactive sites [ that are staffed ]. Employee training programs shall inform personnel responsible for implementing activities identified in the stormwater pollution prevention plan SWPPP or otherwise responsible for stormwater management at all levels of responsibility of the components and goals of the stormwater pollution prevention plan. Training should address topics such as spill response, good housekeeping and material management practices. A pollution prevention plan shall identify periodic dates for such training. All employee training shall be documented in the SWPPP.
h. Management of [ run-off runoff ]. The plan SWPPP shall describe the stormwater [ run-off runoff ] management practices (i.e., permanent structural BMPs) for the facility. These types of BMPs are typically used to divert, infiltrate, reuse, or otherwise reduce pollutants in stormwater discharges from the site. Appropriate measures may include: vegetative swales and practices, reuse of collected stormwater (such as for a process or as an irrigation source), inlet controls (such as oil/water separators), snow management activities, infiltration devices, and wet detention/retention detention or retention devices.
8. Pavement wash waters where no detergents or hazardous cleaning products are used and no spills or leaks of toxic or hazardous materials have occurred (unless all spilled material has been removed). Pavement wash waters shall be managed [ to prevent the discharge of pollutants in a manner to avoid instream impacts ];
