Venters Pit Inspection Date: 04/1212012 Inspection Type: Compliance Evaluation Reason for Visit: Routine Inspection Summary: This mine pit, from a stormwater and wastewater discharge standpoint, is the best designed pit for the management of discharge quality that I have seen in this region. A lot of thought went into managing stormwater and wastewater. Wastewater and much of the stormwater from this pit is directed to either large stormwater sediment traps that provide vegetated filtration and significant storage prior to rising to any level that would discharge from the riser barrel ultimately to a large surface area of rip rap that helps to dissipate the discharge energy and velocity. All but one stormwater trap discharges to a broad wetland area for the use of infiltration, which could feasibly eliminate the need for stormwater sampling. The only discharge point that is conveyed to a ditch is at the north edge of the mine pit along the access road. It is not certain at this time that a discharge from this point actually makes it to surface waters. The discharge may just recharge an adjacent and very dry wetland. The mine pit has a natural grade toward the north north-east corner of the pit where pit dewatering from the active areas are being channelized by an internal ditch that receives water from small ditch rows internal to the pit. The conveyance ditch is located along the perimeter of the pit, outside the 50' undisturbed buffer and meanders adjacent to the wetlands. The mine pit is fairly shallow to avoid the layer of gumbo clay beneath the coarse sand. No pumping is used at this pit. All flow is accomplished via gravity flow with velocities slow enough to avoid scouring. The conveyance ditch discharges to a network of large ponds providing more than adequate settling capacity. An excellent design from a water quality management standpoint. The 50' undisturbed buffer is marked by a silt fence all around the mine pit. The pit is actively discharging wastewater. The wastewater must be monitored quarterly. This is the only deficiency that could be addressed by compliance actions, however, given the efforts taken to provide such an outstanding design and implementation of well maintained BMPs, the inspector would like to allow the permittee time to comply without the need for issuing a Notice of Deficiency.

A requirement to develop a stormwater pollution prevention plan (SWP3) was implemented in the last permit renewal for NCG020000 in January 2010. The SWP3 was due for all permittees operating under the NCG020000 permit on January 1, 2011. Please provide a written SWP3 for this site. The requirements of the SWP3 are described in the NCG020000 permit text. Qualitative Monitoring Yes No NA NE Has the facility conducted its Qualitative Monitoring semi-annually? ❑ ■ ❑ ❑ Comment. Begin semi annual qualitative monitoring for all stormwater outfalls from this facility. Qualitative monitoring is required for every stormwater outfall regardless of representative outfall status. Analytical Monitoring Yes No NA NE Has the facility conducted its Analytical monitoring? ❑ ■ ❑ ❑ # Has the facility conducted its Analytical monitoring from Vehicle Maintenance areas? ❑ ■ ❑ ❑ Page: 3 Permit: NGG020523 Owner - Facility: Venters Pit Inspection Date: 04/12/2012 Inspection Type: Compliance Evaluation Reason for Visit: Routine Comment: Begin semi annual analytical monitoring for the stormwater outfalls from the pit. Also begin quarterly monitoring for the discharge as the result of dewatering activities in the pit. One outfall for wastewater was identified and is located at the outlet to the last settling pond at the north northeast corner of the mine site. The inspector suggested the use of representative outfalls to reduce the number of samples that will need to be collected. The mine site operator will evaluate whether discharges are occuring from the stormwater settling basin at the north side of the pit. It was recommended that this outfall be utilized as the representative outfall for sampling purposes. If it does not discharge, please contact this office to discuss a better location for representative outfall status. Permit and Outfalls Yes No NA NE # Is a copy of the Permit and the Certificate of Coverage available at the site? ❑ Cl ❑ ■ # Were all outfalls observed during the inspection? ■ Q ❑ Q # If the facility has representative outfall status, is it properly documented by the Division? Q ■ ❑ ❑ # Has the facility evaluated all illicit (non stormwater) discharges? 0 ❑ n ■ Comment: There is no office at the mine site for the retention of paperwork. Please ensure a copy of the Certificate of Coverage is accessible. The mine pit does not have representative outfall status, however, the Wilmington Regional Office recommends the use of representative outfall status should the permittee wish to request such. Since there was not a SWP3 prepared, the permittee would not have known that an evaluation of illicit non stormwater discharges is a requirement of the permit. Page: 4 April 17, 2012 Ms. Ashley Rodgers Assistant State Mining Specialist Land Quality Section Division of Land Resources Department of Environment and Natural Resources 1612 Mail Service Center Raleigh, NC 27699-1612 Re: Venters Pit Permit No. 67-57 Onslow County White Oak River Basin Dear Ms. Rodgers, RECEIVED APR 18 2012 LAND QUALITY SECTION Please find enclosed the additional information requested to process our modification and renewal application for the above permitted mine. The responses will correspond with the items in your letter: 1. We have enclosed a check for the $250 requested. 2. The initial 25 foot buffer along the property line contained existing logging paths which had ruts that were allowing surface water to leave the site. To prevent this runoff from leaving the site our operators graded the haul roads to drain into the existing mined areas. In doing this they disturbed the buffer zone but prevented soiled water from draining unto the adjacent property. Therefore, we request a modification to operating conditions #9 and 3C. 3. We have not mined the pit in phases as shown on the original mine application. We discovered upon investigation of the pit that soil types varied on the property. Depending on the type of material required for a project is where the mining operation took place. For example, Area D on the original map, Area E on the original map, and the new Area E on the revised maps all contained clay material that could be used in landfill construction, while Areas A, B, and C contain just general fill material. So it depends on the material needs of a project as to which area of the pit will be utilized. As for dewatering, the original plan was to pump water while mining an area into a basin and let it flow into the wetland. Upon investigation we found that the site would drain naturally if a ditch was dug as shown on the map. We have not had to operate any pumps. Map will be revised to show the different stages of mining activity. As you can see Areas B and C still have large sections that have not been mined at this time. 4. All the details have been combined on to one sheet. See the enclosed Detail sheet. 5. Ms. Willis made a site visit on April 12, 2012. She had no comments concerning the operation and maintenance of the pit except that we need to set up a program to sample the discharge water leaving the site. Once we get her information we will begin those requirements. 6. Mr. Floyd Williams performed the calculations and sized all the erosion control measures that we installed. lie did not provide clear dimensions as to size. We will attempt to show these items, however because of the scale they may not show up very clearly. 7. The permitted acreage on the original mining permit was just wrong. We do not own 273 acres in Onslow County. The original permit requested 90 acres out of the 175 acres listed on the deed to be mined. The reason we only requested that amount was because the wetlands had not been clearly delineated and everyone thought 90 acres would be a safe number. Since then the maps have gotten more accurate and that is why the acreage has changed. The 3 acres for the access road from Highway 111 to the pit has been included and thus the 178 permitted acres. 8. We have not been able to accurately import the delineated wetland map into our computer system and print out a map that shows the wetland limits compared to our existing maps. We have enclosed the latest Google map which the ACOE accepted showing the wetlands. This picture clearly shows some locations where the buffer would be greater than 25 feet as depicted on our mine map. To date we have not been able to import this information into our plans. 9. The part of the pit which will be left as a lake will depend on how much material can be used on any one particular project. Once all the suitable material is mined out of an area and we can maintain a minimum 4 feet of water, that area will be left as a pond. If that is not possible than we will grade the area to drain and reclaim that area. To date the only area completely mined is area E which is graded to drain and a portion of area B which has a small pond section and an area which has been graded to drain. The other areas have not been depleted of material and thus we cannot say which will be left as a pond or which will be graded to drain and reseeded. Please see sheet 2 of 3 for our proposed reclamation plan. If you have any further questions please do not hesitate to call. Thank you.

(Glover)'s — JM Glovers Venters Pit— hereafter referred to as "facility" — to comply with all applicable laws, regulations, permits, and orders. The facility is currently registered with the North Carolina (NC) Department of Environment and Natural Resources (DENR) Division of Energy Mineral and Land Resources (DEMLR), has filed a Notice of Intent (NOI) and has paid the applicable fees for coverage under General Permit No. NCG 020000. Coverage under General Permit No. NCG 020000 is applicable to all owners or operators of stormwater point source discharges associated with facilities that are engaged in the mine dewatering wastewater generation, processing wastewater discharges to surface waters of the state and the discharge of stormwater from an active and inactive mining sites with these activities operating under a Standard Industrial Classification (SIC) 1442. As a requirement of General Permit No. NCG 020000, the permittee shall develop and implement a Stormwater Pollution Prevention Plan, hereafter referred to as the "Plan." The purpose of the Plan is to identify potential sources of stormwater pollution and to develop and implement management practices that minimize pollution in stormwater discharged from the facility. A copy of this plan is kept on file at Glover's corporate office, at the facility (when mining activities are being performed or when representatives of Glover are onsite), or at Glover's nearest field office for review during normal business hours (8:00 AM to 5:00 PM). 2.0 GENERAL FACILITY INFORMATION The facility is composed of one individual parcel of approximately 130.3 acres located at 1857 Catherine Lake Road, in Jacksonville, North Carolina. The location and overview of the parcel is shown on General Location Map in Figure 1. The facility is designated as a borrow pit. This facility is currently inactive. The last excavation event occurred in 2009 and the most recent delivery of soil (stockpiled at the site) in 2010. The facility is utilized as needed for nearby ongoing projects. The facility has three distinct activity related areas: historical pit mining/soil stockpiling areas, delineated wetlands and unmined/undisturbed areas, and vehicle access areas. Stormwater flow across the facility is controlled by natural and modified surface topography. Stormwater that flows across the mine site is generally directed inward from the perimeter of the site which is generally surrounded with a 1-foot berm. Stormwater that does not infiltrate into the ground is ultimately directed eastward toward the one of three discharge points. The stormwater from each of the three discharge points flows into a northern or southern branch of an unnamed tributary of the New River. The three distinct activity related areas and the approximate drainage pathways are shown on the Site Map included as Figures 2. '�h Golder g:lpnojectstgoverlventers plSdraR venters 8wppp(r0).docx Associates May 2015 Draft 2 1530786 3.0 SITE PLAN The following site plan provides a description of the physical and the potential pollutant sources which may be expected to contribute to the contamination of stormwater discharges. The site plan contains the following items as described below. 3.1 Location Map A United States Geological Survey (USGS) topographic quadrangle map was used in the creation of the Site Location Map included as Figure 1. The map extends beyond the facility property boundary and displays general topographic features including the facility's location in relation to transportation routes and adjacent surface water bodies. The USGS topographic map does not illustrate the borrow pit activities and the historical excavation and delivery of soil (stockpiles) at the facility. 3.2 Site Map There are three representative stormwater discharge outfalls (SDOs) located on the facility property: 01, 02, and 03. The approximate location of each SDO is identified on the Figure 2 and shown below. The site map is drawn to scale with a distance legend and depicts the site property boundary, site activity areas, drainage areas for each outfall, and direction of flow in each drainage area. There are no impervious surfaces identified at the facility. Stormwater Discharge Outfall Latitude Longitude 01 34°, 48', 53.23753" N 77°, 32', 09.60735" W 02 340, 48', 48.82773" N 770, 32', 03.47259" W 03 34', 48', 39-54723" N 77, 32', 02.81080" W 3.3 Watershed Identification Map The USGS topographic map does not identify any wetlands surrounding the subject site. Figure 2 identifies areas of the site that have been classified or reported as wetlands by the Williamsburg Environmental Group and the ACFE for the original permit (April 2000). The map identifies the immediate receiving water(s) to which the stormwater outfalls discharge. The receiving water(s) are identified as unnamed tributaries of the New River. The New River basin was not identified by NC DENR as total maximum daily loads (TMDLs) watershed, and as such any associated additional monitoring is not required under the existing permit. 3.4 Significant Materials A significant material, for the purposes of this document, is defined by the NC DENR DEMLR as including but not being limited to: raw materials, fuels, materials such as solvents, detergents and plastic pellets, finished materials such as metallic products, raw materials used in food processing or production; hazardous substances designated under section 101(14) of the Comprehensive Environmental gAprojectslgloverlvenlers pllWratt venters swppp(rp1) docx V� Golder Associates May 2015 Draft 3 1530786 Response, Compensation, and Liability Act (CERCLA); any chemical the facility is required to report pursuant to section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA); and fertilizers, pesticides and waste products such as ashes, slag and sludge that have the potential. to be released with Stormwater discharges. Any additional materials and/or chemicals introduced to the site must be reviewed to determine appropriate reporting requirements under Federal and State law. The facility does not store any significant materials. 3.4. T Outdoor Process Areas As stated in Section 2.0, the facility is currently inactive; the last excavation occurred in 2009. The facility is comprised of three distinct activity ' related areas: pit mining/soil stockpiling areas, wetlands/unmined/undisturbed areas, and vehicle access areas. 3.4.2 Vehicle Maintenance Fueling Process Areas The facility does not conduct or have onsite maintenance or fueling capabilities. A historical secondary containment structure was identified along the northwestern side of the property. This structure was reported to have contained an above -ground storage tank (AST) used for historical refueling activities (diesel). At the time of the site visit, the AST was not present and the secondary containment structure was abandoned. Stormwater flow in this area is primarily to the east toward SDO01 and SDO02. 3.5 Significant Spills / Leaks There have been no significant spills or leaks of pollutants at this facility identified by facility management, as of the date of this Plan. Spills of any volume are to be handled per spill response procedures in Section 5.0. 3.6 Stormwater Outfall Certification Appendix A of the Plan contains the Stormwater Pollution Prevention Plan Certification and Appendix B contains the Annual Non-Stormwater Discharge Certification. The certification statements are to be signed by a responsible corporate officer or by a duly authorized representative in accordance with the requirements of Part IV, Section B, Paragraph 5 of the general permit. 4.0 EROSION AND SEDIMENT CONTROL The facility manages and maintains their erosion and sediment controls through the NC DENR — Department of Natural Resources Division mining permit (Permit No. 67-57). The permit is in effect until July 27, 2022, and requires the facility to implement various engineering and institutional controls to maintain and manage sediment accumulation and reduce/eliminate erosion. The applicable components of the mining permit that have potential to impact the implementation of this SWPPP include: e Sufficient buffer (minimum 25-foot undisturbed) shall be maintained between and affected land and any adjoining waterway or wetland ti prevent sedimentation of that waterway or 9jedMgloverlventers pitltlrah venters swppp{rplj.dacx G � Gvider Associates ' May 2015 Draft 4 1530786 wetland from erosion of the affected land and preserve the integrity of the natural water course. ■ Adequate mechanical barriers including but not limited to diversions, earthen dikes, sediment check dams, sediment retarding structures, rip rap pits, or ditches shall provide in the initial stages of any land disturbance and maintained to prevent sediment from discharging into adjacent surface areas or into any lake, wetland, or natural watercourse in proximity to the affected lands. i All drainage from the affected areas around the mine excavation shall be diverted internal to said excavations or into existing sediment basins. ■ The angle of graded slopes and fills shall be no greater than the angle which can be retained by vegetative cover or other adequate erosion control measure, structure, or device. In any event, exposure slopes of any excavated channels, the erosion of which may cause off -site damage because of sedimentation, shall be planted or otherwise provide ground cover, devices or structures sufficient to restrain such erosion. ® The affected land shall be graded so as to prevent collection of ponds of water that are likely to become noxious or foul. Necessary structures such as drainage ditches or conduits shall be constructed or installed when required to prevent such conditions. ■ The final slopes in all excavations in soil sand gravel and other unconsolidated materials shall be at such an angle to minimize the possibility of slides and me consistent with the future use of the land. ■ A revegetation plan shall conform to acceptable and recommended agronomic and reforestation practices as established by the NC Agriculture Experiment Station and the NC Forest Service. ® Side slopes to the lake excavation shall be graded to a 3 horizontal to 1 vertical or flatter to the water and 2 horizontal to 1 vertical or flatter below the water line. ■ All other final perimeter side slopes shall be graded to a 3 horizontal to 1 vertical or flatter slope. ® Compacted surfaces shall be disced, subsoiled, or otherwise prepared before revegetation ■ Any revegetation plan activities shall comply with the seeding, planting and amendments specifications outlined in the mining permit. 5.0 STORMWATER MANAGEMENT PLAN The stormwater management plan contains a description of the materials management practices that the facility employs to control or minimize the exposure of significant materials to stormwater, including structural and non-structural controls. 5.1 Feasibility Study Whenever practical, the facility shall prevent exposure of storage areas, material handling operations, manufacturing, and fueling or vehicle maintenance operations to stormwater. The facility's operations status is inactive (last operated in 2010) therefore a feasibility study is unnecessary at this time. Should the facility return to and active operational status, the facility shall assess the stormwater exposure to storage areas, material handling operations, manufacturing, and fueling or vehicle maintenance operations prior to the reinitiating of facility operations. In such an event, practical and economically -# ` Golder rdettsl overlventers iWraft venters s .docx Associates 9 W 1 � P h'PPPirWI May 2015 Draft 5 1530786 feasible efforts will be made to limit run-on and run-off by diverting stormwater away from areas where significant materials may be exposed to stormwater. 5.2 Secondary Containment The general permit states that secondary containment is required for the bulk storage of liquid materials; storage in any amount of Section 313 of Title III of the SARA water priority chemicals; and storage in any amount of hazardous substances, in order to prevent leaks and spills from contaminating stormwater runoff. At the time of the site visit there were no bulk storage of liquid materials, SARA (Section 313 of Title III) water priority chemicals, or hazardous substances used or stored on the subject property. Should these types of chemicals be used or stored on site in the future, the appropriate secondary containment will be needed at the time of use. 5.3 Best Management Practices (BMPs) BMPs are defined in General Permit No. NCG020000 as measures or practices used to reduce the amount of pollution entering surface waters; BMPs may take the form of a process, activity, or physical structure. The installation and implementation of BMPs at the facility is based on the assessed potential for sources to contribute significant amounts of pollutants to stormwater discharges; as well as, historical data collected from stormwater discharge monitoring. The most basic BMPs at the facility include proper conveyance of stormwater from the pit mining/soil and stockpiling areas, which is achieved by the use of swales and a stormwater drainage system. Should excavation or stockpiling of soil resume at the facility, the on -site activities should be performed in a manner to minimize exposure to precipitation. 6.0 SPILL PREVENTION AND RESPONSE PLAN (SPRP) The purpose of the SPRP is to prevent the discharge of petroleum and/or hazardous materials into the waters of North Carolina per 40 CFR 112. The plan is aimed at preventing spills from occurring, as well as, describing clean-up and recovery measures. As part of the spill response plan, the facility has a Pollution Prevention Team that will be responsible for assessing the need to implement spill response measures. Additionally, a trained person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. Spills or releases, excluding minor spills within containment areas, will be reported to a member of the Pollution Prevention Team and cleaned up as soon as possible. Section 11.1 of this Plan outlines additional reporting requirements that may be necessary. The following personnel are the designated Pollution Prevention Team: g)projecMgloverWenters pitWraft venters swppp(rpl).docx GlGolder ssociates Primary Contact: Armon Pfeifer May 2015 Draft 6 1530786 Co., Inc. , North Carolina 27866 Secondary Contact: GTove onstmdion Co., Inc. P.O. Box 0 Pleasant l4lill, North Carolina 27866 Off e Cell Potential Pollution Sources The areas of potential pollution sources are listed in Section 3 and Section 4 of this Plan. The facility's operations status is inactive (last operated in 2010) therefore a feasibility study is unnecessary at this time. Should the facility return to and active operational status, the facility shall assess the stormwater exposure to storage areas, material handling operations, manufacturing, and fueling or vehicle maintenance operations prior to the reinitiating of facility operations. 6.2 Material Handling and Storage Practices and Spill Control Equipment The facility historically conducted soil excavation and stockpiling operations on -site. The historic activities likely involved the storage and used materials at include diesel fuel (on and off -road), used oil, motor oil, hydraulic fluid, gear oils, greases, gasoline, and degreasing solvents on -site for the completion of daily operations. However, since the facility's operations status is inactive (last operated in 2010) and no chemicals of chemical storage structures were observed for the site visit, the requirement for both structural and non-structural BMPs to reduce the possibility of spills and releases of significant materials to the environment and the need for on -site spill control equipment is not necessary. Should the facility return to an active operational status, the facility shall assess the material handling and storage practices and identify the necessary spill control equipment necessary to adequately respond to spill event prior to the reinitiating of facility operations.�� 7.0 PREVENTATIVE MAINTENANCE AND GOOD HOUSEKEEPING As part of the preventative maintenance and good housekeeping program, members of the facility Pollution Prevention Team, or other designated qualified employees, will perform inspections of the facility g: projectslgloveAventers polerart venters swppp(rpl).docx Golder Associates I - _Wi -- May 2015 Draft 7 1530786 and stormwater systems (see the "Semi-annual Stormwater Management System Inspection Form" in Appendix D). These inspections will take place on a semi-annual basis. The first inspection will occur within the second half of the year (July - December) and the second inspection will take place in the first half of the new year (January - June 2016). A minimum of 60-days must separate each inspection. This form is also used to determine required for updating the Plan to include any changes to the facility's operation. The completed inspection forms are filed in the General Manager's office to document the findings and/or corrective measures undertaken. Inspection reports shall be kept with the Plan at the facility for at least five (5) years. The facility also employs good housekeeping practices to minimize contact of materials with stormwater. Specific good housekeeping practices are as follows.- i Each worker is responsible for good housekeeping practices in their work area. Any improperly working equipment or leaks will be reported to a member of the pollution prevention team for further assessment and corrective action. ■ Any spills outside of containment structures will be cleaned as soon as possible. No spills will be washed into the stormwater conveyances on site. ® Employees will ensure that soils delivered to the site are place in the proper staging area. Material handling equipment, such as excavators, will only be operated by qualified personnel, e Facility personnel will oversee the onsite refueling activities and observe any filling and removal of liquids from containers to minimize spills and overfills. ® Equipment maintenance or repairs shall be performed off -site if feasible. Waste fluids generated from the maintenance of equipment shall be properly collected and disposed. 8.0 EMPLOYEE TRAINING All facility personnel shall be trained in accordance to the procedures, goals, and components of the Plan. New employees will not be allowed to work unsupervised until they have been properly trained in the areas of the Plan related to their daily duties. Training will be provided to facility personnel on an annual basis. Additional training will be provided as necessary for operational modifications, equipment malfunctions resulting in spills or releases, or for other stormwater related issues. The training program will be conducted by the General Manager or other duly appointed qualified person. Documentation of each training session will be recorded on a training log and maintained with this Plan for a period of 5- years. 9.0 RESPONSIBLE PARTY As a requirement of NCG020000 a specific position must be identified that is responsible for the overall coordination, development, implementation, and revision to the Plan. The facility has established a Pollution Prevention Team, listed in Section 5 of this Plan, which will be responsible for the coordination, gipr0jectS5g1overlventers pi[Wraft venters swppp(rpl).docx Golder Associates May 2015 Draft 8 1530786 implementation, and revision to the Plan. The primary contact listed in the Pollution Prevention Team will also meet the signatory requirements outlined in Part IV. Section 13.5 of the general permit. 10.0 PLAN AMENDMENTS The facility will update and amend this Plan whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the Plan shall be reviewed and updated on an annual basis. The annual update will include: ■ An updated list of significant spills or leaks of pollutants for the previous three years, or the notation that no spills have occurred. 0 A written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. ■ A documented re-evaluation of the effectiveness of the BMPs listed in the Plan. 11.0 QUANTITATIVE AND QUALITATIVE MONITORING Monitoring of the three facility outfalls (SDO 01, 02, and 03) will be performed on a semi-annual basis in accordance with Part III. Sections S-D of the General Permit; and reporting will be performed in accordance with Part IV Section E. The following sections will outline the analytical and visual inspection programs and associated reporting for compliance with the General Permit. 11.1 Analytical (Quantitative) Monitoring The requirements for analytical monitoring of stormwater discharges are outlined in Part III, Section B of the General Permit. The General Permit requires samples to be collected on a semi-annual basis, during a representative storm event, at each SDO unless representative status is granted.,The sample will be taken on a day and time that is characteristic of the discharge and before the discharge joins or is diluted by any other waste stream, body of water, or substance. A representative storm event is defined as a storm event that measures greater than 0.1 inches of rainfall and that occurs at least 72 hours form the previously measurable (greater than 0.1 inches) storm event. Grab samples should be collected within the first thirty minutes of discharge from the SDO. During each representative storm event in which samples are collected, the total precipitation must be recorded from an on -site or local rain -gauge. The following (Tablel) lists the required analytical parameters: gAprojects%Jover%venters pitl&afl venters swppp(rpl).docx 99 Golder Associates May 2015 Draft 9 1530786 TABLE 9: Analytical Monitoring Requirements Parameter Units Frequency Sample Type Location Settleable Solids ml/L Semi-annual Grab SDO: 1, 2, & 3 Total Suspended mg/L Semi-annual Grab SDO: 1, 2, & 3 Turbidity N.T.U.
