Re: Gloucester County Utilities Authority / Gloucester County Improvement Authority Amendment to Gloucester County Solid Management Plan (GCSWMP) Our File No. 0800M060

Sir/Madam,

Remington & Vernick Engineers (RVE) is submitting this request on behalf of the Gloucester County Improvement Authority (GCIA) and the Gloucester County Utilities Authority (GCUA), to amend the Gloucester County Solid Plan (SWMP) to include the use of non- hazardous dry sludge (Classified as ID 12) as part of a blend with other authorized alternative cover material for use as at the GCIA facility.

RVE has been working with GCIA and GCUA to get NJDEP (Department) approval to evaluate the effectiveness of using as part of a blend with or other authorized alternative cover materials for use as a daily cover material. The biosolids are being generated at GCUA, a sister agency, as part of sludge handling during the wastewater treatment process.

GCUA operates a Publicly Owned Treatment Works (POTW) to treat wastewater generated from domestic and industrial sources in the residential and commercial areas of southern New Jersey. The POTW is located at 2 Paradise Road, Thorofare, New Jersey, 08066 in West Deptford Township.

The GCUA continues to seek new beneficial use options to effectively manage the sludge generated at its facility. Significant cost savings may be possible through reduced transportation distances, logistics, and sludge management costs, if the biosolids generated at GCUA can be used beneficially at GCIA as an alternative daily cover. Besides cost reduction for GCUA, beneficial use of biosolids as daily cover at GCIA offers other potential benefits such as:

• Reduced need for traditional clean soil resources; • Lower cost to meet landfill cover needs; • Create a foundation for opportunities for using biosolids to fulfill cover needs at other ; and • Maintain the highest economic benefit of biosolids management within New Jersey.

In accordance with the Department’s Division of Solid & Regulations and Technical Manuals, the use of an alternative material for daily landfill cover must be approved as a modification to a Sanitary Landfill Facility permit. Since biosolids is not a soil and is a non- traditional non-hazardous cover material classified as ID 12 (dry sewage sludge), the Department provides that its use may be evaluated in accordance with the requirements for Research Development & Demonstration (RD&D) projects outlined in N.J.A.C. 7:26-2A.8(b)19.

The Department requested GCIA to establish and submit a RD&D protocol to evaluate the use of biosolids as alternative cover material. The RD&D application was submitted by RVE on October 27, 2017 and was subsequently approved by the Department on April 11, 2018. Correspondence between GCIA and the Department, the RD&D application, and the Department approval are included as Attachment A for reference. The RD&D application contains all the information requested in the Gloucester County Procedures and guidelines for Gloucester County Waste Management Plan inclusion of recycling and solid waste facilities.

A modification to the existing RD&D application was submitted in September 2018 and was subsequently approved by the Department on January 23, 2020. Per the approval, permission was granted to GCUA to conduct the RD&D project using two (2) digested biosolids streams. The approval allows GCIA to accept no more than 100 tons of digested GCUA biosolids per day. The GCUA biosolids treated with or without the proprietary O’Rege process are accepted on a daily basis and are currently applied as a blended material mixed with soil or other authorized alternative cover material such as ID 27 contaminated soil, automobile shredder residue or recycled glass aggregate. The modified RD&D application along with relevant NJDEP correspondence is included as Attachment B for reference.

Biosolids generated at GCUA have been evaluated for use as alternate daily cover at GCIA since April 2018. Based on the observations by GCIA staff and RVE representatives in accordance with the RD&D, the blended biosolids material has provided adequate cover. There were no observations of exposed waste material; evidence of any vectors, rodents or burrows; from covered landfill surfaces; erosion caused by rain or wind; or dust generation. There were no observations of ponding or any evidence of excessive runoff that would result from any impervious cover material. There were no observations of fire or any evidence suggesting the biosolids blended cover will not provide an adequate fire break.

Based on the observations above, it is our conclusion that the biosolids blend provided a suitable and adequate daily cover meeting the performance criteria set forth in the Department’s regulations (N.J.A.C. 7:26-2A.8(b)15i through v.

RVE requests that the Gloucester County SWMP be modified to include the use of non-hazardous dry sewage sludge (Classified as ID 12) as part of a blend with other authorized alternative cover material for use as daily cover at the GCIA landfill facility. Subsequent to the SWMP amendment, RVE will submit a permit modification application to the Department to modify GCIA’s solid waste

The Gloucester County Solid Waste Complex is owned and operated by the Gloucester County Improvement Authority (GCIA). Located in South Harrison Township, the Solid Waste Complex is a sanitary landfill situated on a 540-acre tract of land. Currently the active landfill and supporting structures utilize 20 percent of the available area, the balance of the site remains undeveloped with parts used as a grassland bird habitat, for storm water management and a visual buffer. A Site Plan is included as Appendix .

GCIA is seeking a Research Development and Demonstration (RD&D) approval from NJDEP (Department) to evaluate the effectiveness of using biosolids as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The biosolids will be generated at the Gloucester County Utilities Authority (GCUA), a sister agency, as part of sludge handling during the wastewater treatment process. The effectiveness of the alternative daily cover (biosolids) will be evaluated over a twelve-month (12) period by monitoring its use under varying operational and weather conditions. Should the RD&D provide favorable results, GCIA anticipates seeking longer term approval through a permit modification.

GCUA operates a Publicly Owned Treatment Works (POTW) to treat wastewater generated from domestic and industrial sources in the residential and commercial areas of southern New Jersey. The POTW is located at 2 Paradise Road, Thorofare, New Jersey, 08066 in West Deptford Township.

The GCUA continues to seek new beneficial use options to effectively manage the sludge generated at its facility. Significant cost savings may be possible through reduced transportation distances, logistics, and sludge management costs, if the biosolids generated at GCUA can be used beneficially at GCIA as an alternative daily cover. Besides cost reduction for GCUA, beneficial use of biosolids as daily cover at GCIA offers other potential benefits such as:

• Reduced need for traditional clean soil resources; • Lower cost to meet landfill cover needs; • Create a foundation for opportunities for using biosolids to fulfill cover needs at other landfills; and • Maintain the highest economic benefit of biosolids management within New Jersey.

In accordance with the Department’s Division of Solid & Hazardous Waste Regulations and Technical Manuals, the use of an alternative material for daily landfill cover must be approved as a modification to a Sanitary Landfill Facility permit. Since biosolids is not a soil and is a non- traditional cover material, the Department provides that its use may be evaluated in accordance with the requirements for RD&D projects outlined in N.J.A.C. 7:26-2A.8(b)19.

The Department requested GCIA to establish and submit a RD&D protocol to evaluate the use of biosolids as alternative cover material. Correspondence between GCIA and the Department, including a copy of the Departments request is included as Appendix II. This application, prepared on behalf of GCIA, by Remington & Vernick Engineers (RVE), serves to fulfill that request.

NJDEP regulations applicable to the management of solid waste provide for an exemption from a full facility permit for RD&D projects to test and evaluate new or innovative technology or new innovative operational process modifications made to existing solid waste facilities or operations. The regulations, published at N.J.A.C. 7:26-1.7(f), require that a RD&D must be designed, constructed and operated consistent with applicable environmental statutes, rules, permits, approvals or orders.

PROJECT SPONSOR

GCIA is seeking a RD&D approval from the NJDEP to evaluate the effectiveness of using sludge derived biosolids as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The 12-month project will assess the effectiveness of biosolids as an alternative cover material by monitoring its use under varying operational and weather conditions. Should the evaluation provide favorable results, GCIA anticipates seeking longer term approval through a permit modification. Accordingly, GCIA will serve as the project sponsor and applicant for the permit modification to utilize biosolids material as an alternative cover pursuant to Department requirements.

BIOSOLIDS PRODUCT GENERATOR INFORMATION

The GCUA wastewater treatment plant is in the process of upgrading their sludge handling process to produce an air-entrained, dewatered sludge product in the form of a biosolid. The enhanced biosolid is achieved due to conditioning thickened sludge using a proprietary Solid Liquid Gas (SLG) technology. The conditioned sludge will pass through a belt filter press for further dewatering, prior to it being transported for off-site disposal. The SLG technology is a patented process manufactured by Orege North America. The process increases cake dryness with a workable texture sludge reducing polymer usage and odor. The biosolids are air entrained prior to polymer addition and the belt filter press operation. The SLG technology will be installed upstream of one (1) dedicated belt filter press. Currently, this process is being used in Lehigh County, PA, where the sludge generated at the County’s wastewater treatment plant is conditioned with the SLG process and the biosolids produced are land applied to approximately one hundred (100) farms.

BIOSOLIDS PRODUCT STORAGE AND TRANSPORTATION

The air-entrained, dewatered sludge product is a recovered non-hazardous biosolids resource, classified Dry Sewage Sludge (waste type ID 12), per the NJDEP solid waste regulations as. The biosolids product will be stored at the GCUA until it can be beneficially reclaimed at the GCIA.

The enhanced, dewatered biosolids will be conveyed from the discharge end of the belt filter press via a series of belt conveyors to a storage area at the GCUA. The storage area contains dedicated storage for holding and loading the biosolids.

Truck routes will be consistent to those currently utilized by the GCUA when hauling incinerator ash to the GCIA. These are the same routes used in conveying GCIA leachate to the GCUA. Significant adverse impact to road traffic is not anticipated during the course of this RD&D.

ENVIRONMENTAL, ENGINEERING CONSULTING AND SUPPORT SERVICES

Environmental, engineering consulting and support services for this RD&D will be provided on behalf of the GCUA and the GCIA by Remington & Vernick Engineers (RVE). RVE has prepared the RD&D Application, proposed assessment, evaluation and reporting documents. RVE will provide oversight as necessary through the course of the RD&D to ensure that the terms of a RD&D approval issued by the NJDEP are implemented and that the RD&D findings are reported accurately. RVE shall serve the project as a team member along with the GCIA, GCUA, and NJDEP.

BACKGROUND

Although sludge derived biosolids products have been successfully used in New Jersey and other states as landfill cover material, a complete demonstration of how the GCUA material will meet NJDEP’s regulatory requirements applicable to cover material has not been completed in a formal assessment report. NJDEP’s regulations and technical guidance manuals allow for appropriately permitted solid waste landfill facilities to seek approval for alternative landfill cover materials. The regulations establish many behavioral, physical and analytical criteria for alternative cover materials and set forth landfill permit modification applications guidelines. For non-traditional landfill cover materials which may not possess soil-like properties, the Department provides that the cover material may be evaluated in accordance with the requirements for RD&D projects (see N.J.A.C. 7:26-2A.8(b)15-19.

The RD&D regulations published at N.J.A.C. 7:26-1.7(f)4 require that a RD&D project shall be included by administrative action within the district solid waste management plan for the county or district within which the project is located on the Statewide Solid Waste Management Plan.

GCIA has filed an application with the NJDEP to amend the Certified District Solid Waste Management Plan for the County of Gloucester in accordance with the NJDEP regulations for solid waste planning (N.J.A.C. 7:26-6.11). The Administrative Action Application allows the receipt by the GCIA at its permitted landfill in South Harrison Township of biosolids sludge derived product (waste Type 12) generated by the GCUA at its POTW in West Deptford Township, New Jersey for the purpose of testing for use as alternative landfill cover material in accordance with terms of any approval that may be issued by the NJDEP pursuant to the Department’s landfill and/or RD&D regulations.

OBJECTIVES

The SLG technology is currently used to treat sludge from a wastewater treatment facility in Lehigh County, PA to generate biosolids that are then applied as alternative daily cover at the County Landfill. GCIA believes that the technology can be successfully applied to the sludge generated at GCUA and the biosolids sludge derived product can be used as a blend with other authorized alternative cover materials at the GCIA landfill. The RD&D project aims to successfully demonstrate the compliance of the GCUA biosolids with sanitary landfill daily cover performance requirements as outlined in New Jersey’s landfill regulations. These regulations require that a landfill cover:

• Adequately cover the waste fill; • Impede the entry of rodents and vectors into the waste fill; • Control malodorous emissions from the waste fill; • Provide a fire break; • Resist water erosion; • Resist wind erosion; and • Reduce the occurrence of windblown litter

\\rve232\Groups\Facilities\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\residuals\RDD\Application\GCIA RD&D Application.docx | Page | 5 Visual inspection of the air entrained biosolids generated from the SLG process do not exhibit any limiting factors that might prevent its use as alternative daily cover. GCIA believes that the alternative cover material will allow the percolation of rain and snow melt to readily pass through the landfill profile and reach the leachate collection system with little to no potential for leachate outcrops to form at the landfill surface. GCIA does not anticipate any pressure buildup due to accumulation of landfill gases under the biosolids. Generally, the biosolids will exhibit all characteristics that are typical of soil that is used as daily cover.

BIOSOLIDS PRODUCT PHYSICAL AND ANALYTICAL PROPERTIES

The biosolids product is an enhanced dewatered sludge produced by conditioning the GCUA sludge with the SLG technology at GCUA’s facility in West Deptford Township. The material is a non-hazardous material in accordance with NJDEP 2015 Residential Standards classification requirements. The moisture content can vary, but is typically between 70 to 80 percent by weight. The material has a mild musty soil like odor.

SCOPE

GCIA proposes that the RD&D be authorized for a period of one (1) year between November 2017 through October 2018. This will provide for a thorough assessment of the biosolids material as a blend with other materials to meet the requirements of daily cover material in accordance with the procedures outlined herein. GCIA proposes to accept less than 100 tons per day of the biosolids sludge derived product to be tested for use as alternative landfill cover material. Daily delivery volume and tonnage will be monitored and adjusted by GCIA as needed based on availability and delivery of authorized alternative cover material for blending with the biosolids. The product will be delivered to the GCIA landfill on a 5 or 6 day per week basis, on an active portion of the landfill in close proximity to the working face. GCIA does not envision a need for stockpiles. Material will be delivered only during operational hours in accordance with GCIA’s landfill permit. The biosolids sludge derived landfill cover product can be applied with traditional landfill operational equipment as blended material mixed with soil or other authorized alternative cover material such as ID 27 contaminated soil or Automobile Shredder Residue (“ASR”) or Recycled Glass Aggregate (“RGA”). The material can be spread with a bulldozer, landfill compactor or equivalent earth handling equipment. The material will be applied and compacted to a minimum thickness of six (6) inches as a mixture that is blended or interspersed with soil or other authorized alternative cover material. The respective cover materials will be pushed through and over each other, in the prescribed ratios, by a bulldozer, landfill compactor or other equivalent equipment such that a mixture of or a patch work of different materials will be evident in the applied cover. The amount of biosolids material to be applied in alternative cover blends will be limited to a maximum of 50% biosolids which is one (1) part by volume of biosolids to one (1) part soil or alternative cover material. This RD&D application includes evaluation of the biosolids as a daily cover material blended with soil or other approved alternative cover material (ID 27 contaminated soil; Automobile Shredder Residue (ASR); or Recycled Glass Aggregate (RGA)).

• Staging and material management procedures to assure

o Placement of the product near the active working face of the landfill on lined areas of the site with provisions for the collection of landfill leachate

o Staging and material management precautions to contain runoff to direct potentially contaminated liquid to the leachate management system of the landfill

• Spreading, application and blending methods; • Equipment utilization; and • Observation evaluation, testing requirements and reporting protocols.

RD&D DEMONSTRATION REQUIREMENTS

The required criteria and requirements that need to be met for the RD&D testing are summarized below. For ease of reference, the criteria are typed in bold. The material properties that GCIA believes provides the requisite control and the evaluation technique proposed to assess the property follows in Italics.

1) Alternative Landfill Cover Requirements [N.J.A.C. 7:26-2A.8(b)15]

In accordance with NJDEP landfill regulations N.J.A.C. 7:26-2A.8(b)7, all exposed surfaces of solid waste shall be covered at the close of each operating day with a daily cover consisting of six inches of compacted clean soil or alternative cover material subject to the approval of the Department. Any alternative cover material must meet the guidance as set forth in the Department’s “Technical Manual for Cover Material Requests” and meet the following criteria as outlined in N.J.A.C 7:26-2A.8(b)15: i) 7:26-2A.8(b)15.i – The alternative material must impede the entry of rodents and vectors into the waste fill;

Response: The biosolids landfill cover product applied as a blended material mixed with soil or other authorized alternative cover material will provide a barrier to impede the entry of rodents and vectors into the compacted waste material.

Assessment of Performance: Observations will be conducted by visual observation and will be documented as needed by photographs of the application of the product and/or blended material. Observations for rodent activity or visible burrows will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager: and semi-monthly by RVE. Notation of observations will be recorded on the cover material inspection form (see Appendix III) by the landfill manager and RVE during

\\rve232\Groups\Facilities\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\residuals\RDD\Application\GCIA RD&D Application.docx | Page | 7 observations. If landfill personnel identify any evidence of rodent activity or habitat, same will be made known to the landfill manager and RVE.

ii) 7:26-2A.8(b)15.ii – The alternative material must control malodorous emissions;

Response: The minimum thickness of the biosolids and blended material to be used as alternative daily cover will be at least six (6) inches so as to assist in the mitigation of excessive release of solid waste odors. The biosolids developed through the SLG solution technology treatment process will be aerated, thereby reducing typical sewage sludge odors. The biosolids emit a slight musty soil like odor.

Assessment of Performance: Observations will be conducted by sense of smell and will be recorded on the Cover Material Inspection Form (See Appendix III) by the landfill manager and RVE during observations. Odor observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager: and semi-monthly by RVE. If landfill personnel identify any offensive odor emission, it will be brought to the attention of the landfill manager and RVE.

iii) 7:26-2A.8(b)15.iii – The alternative material must provide a firebreak;

Response: The occurrences of fires at well managed landfills are rare. The disposal and compaction of waste material in controlled lift thicknesses that are covered to provide a structural separation of waste materials coupled with the implementation of engineered controls has virtually eliminated landfill fire potential. The biosolids alternative cover blend material will provide a structural separation to compacted waste layers or lifts thus providing a physical fire break. The delivered biosolids product has a moisture content of approximately 70 to 80 percent that will aid in the prevention of fires and migration of fire should one occur. This moisture content in conjunction with proper solid waste lift construction and proper management of landfill gases will provide protection against the occurrence of landfill fires.

Assessment of Performance: Observations will be conducted visually and by sense of smell for any evidence of excessive temperature, smoke, or fire. Observations will be recorded on the Cover Material Inspection Form (See Appendix III). Observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

iv) 7:26-2A.8(b)15.iv – The alternative material must resist erosion;

Response: The biosolids material has similar physical properties to soil and many traditionally accepted alternative landfill cover materials. The fibrous nature of the product and polymers added as part of the treatment process add binding properties to resist the effects of water erosion.

\\rve232\Groups\Facilities\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\residuals\RDD\Application\GCIA RD&D Application.docx | Page | 8 Assessment of Performance: Observations will be conducted and documented as needed by photographs of alternative cover material following exposure to significant rain events. Observations for visible erosion will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi- monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix III) by the landfill manager and RVE. Additional observation frequency will be as needed following rain events or if landfill personnel identify any increased evidence of stormwater erosion. v) 7:26-2A.8(b)15.iv – The alternative material must not be easily windblown;

Response: The biosolids have a moisture content of approximately 70 to 80 percent which aids in the prevention of dust attributable to biosolids covered areas. Although dust caused by windblown fine particles of soil and alternative cover material can occur during extremely dry and high wind conditions even at well managed sanitary landfill facilities, it is expected that the moisture content of the subject biosolids will minimize this condition.

Assessment of Performance: Observations will be conducted for dust and will be documented as needed by photographs (if possible) of dust emanating from biosolids covered areas. The schedule of observations for dust will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix III). If landfill personnel identify any dust presence relating to the biosolids, it will be brought to the attention of the landfill manager and RVE. vi) 7:26-2A.8(b)15.v – The alternative material must control windblown litter;

Response: Windblown litter is a common occurrence at sanitary landfills; routine litter cleanup must always be conducted. The biosolids material has similar physical properties to soil and many traditionally accepted alternative landfill cover materials and should provide an effective control measure to mitigate the occurrence of windblown waste material similar to that provided by traditional daily cover material.

Assessment of Performance: Observations will be conducted for increased evidence of windblown litter and will be documented as needed by photographs when there is a determination that the litter emanated from areas subject to biosolids cover under the RD&D pilot testing program. The initial schedule of observations for litter will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix III). If landfill personnel identify any increased evidence of litter attributable to biosolids covered areas, the landfill manager and RVE will be notified.

For purposes of assuring material manageability, preventing contaminated surface water runoff, allowing the controlled venting of landfill gases and, reducing the occurrence of fires, NJDEP has published regulatory criteria for the percent of combustible and material grain size distribution. We note that several of the purposes mirror the requirements of those set forth at N.J.A.C. 7:26- 2A.8(b)15 and can be evaluated in the manner detailed in the proposed performance assessments in section 1 above. The required criteria are summarized below with the regulatory reference pursuant to N.J.A.C. followed by the material properties we believe provide the requisite control and the evaluation technique proposed to assess the property.

i) 7:26-2A.8(b)16.i – The volatile solids or combustible content of the cover shall not exceed 12 percent by weight;

Response: Historically GCUA blended solids have been tested for total solids and volatile solids on a daily basis. This material averages 4.5% total solids with volatile solids comprising 78-82%. It is anticipated that the SLG air-entrained biosolids used as daily cover will be dewatered to 20-30% total solids by weight, while the remaining 70 to 80% of the product will be liquid. The dewater biosolids will be used in a 1:1 blend by volume with other approved daily cover. Accounting for the blend, the percent by weight of volatile solids is not expected to exceed 12%.

Assessment of Performance: GCUA will conduct daily analytical for total solids and volatile solids of the biosolids product at their in-house laboratory facility throughout the course of the RD&D. Also, GCUA will conduct an analytical of total solids and volatile solids of the GCIA daily cover material prior to blending with the biosolid, along with a measurement of SLG air-entrained biosolids density to convert from volume to weight for calculations. The results and calculations will be provided as part of a final report submitted at the conclusion of the RD&D. ii) 7:26-2A.8(b)16.ii – No more than 20 percent of fine grained materials shall pass No. 200 sieve;

Response: Use of biosolids as an individual daily cover material or in combination with soil or other authorized alternative cover material as a daily cover material will meet the underlying intent of this particle size standard.

• To prevent the formation of impervious vertical barriers to the downward flow of leachate that may lead to leachate outcrops and potential offsite discharge of leachate as stormwater. • To prevent vertical barriers to the upward flow of landfill gas that may lead to lateral migration of potentially explosive or flammable gases from the landfill property. • To provide filtration or adsorption of potentially odorous gases that vent to the landfill surface to reduce off-site odor impacts. • To reduce wind and water erosion of fine grained particles of cover material that can contribute to dust emissions in air and sediment transport to surface water.

\\rve232\Groups\Facilities\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\residuals\RDD\Application\GCIA RD&D Application.docx | Page | 10 Accordingly, the final condition of the biosolids cover will allow leachate to easily percolate through the landfill profile and reach the leachate collection system with little to no potential for leachate outcrops to form at the landfill surface. Likewise, landfill gases will permeate the biosolids at a rate that will prevent undue pressure build up. The structure and moisture retention properties of the biosolids will promote the adsorption of odorous compounds that may be entrained in the landfill gas.

Assessment of Performance: The GCUA, in cooperation with the GCIA, have completed particle size distribution analyses on a variety of biosolids materials with results presented in the Analytical Report dated 11/25/15, Appendix IV. The analyses evaluated the impact of digestion, dewatering, and drying on the grain size distribution of a biosolid. The results showed the biosolids met the gradation restrictions of > 40% passing a #10 sieve and < 20% passing a #200 sieve, regardless of processing techniques.

During the RD&D, a particle size distribution analysis will be conducted on the biosolids material for use as daily cover once a month.

iii) 7:26-2A.8(b)16.iii - At least 40 percent by weight of the fragments in the soil admixture shall be capable of passing through a No. 10 mesh sieve;

Response: The underlying intent of this criteria is to avoid the use of extremely coarse grained materials such as gravel and stone so as to reduce the volume of voids. Coarse grained materials when used as daily cover can lead to offsite migration of landfill gases as the gas can readily escape through the voids into the atmosphere.

During the RD&D, a particle size distribution analysis will be conducted on the biosolids material for use as daily cover once a month. iv) 7:26-2A.8(b)16.iv - Particle sizes shall not exceed six (6) inches in diameter;

Response: Particles are limited in size to six (6) inches, which is consistent with the minimum depth of cover. up to six (6) inches are classified as silts, sands, and small gravels. Combinations of these classifications will work on-site to provide structure and integrity to the layer of daily cover.

Biosolids when spread is not anticipated to result in particle sizes approaching six (6) inches. The presence or absence of large particles can be determined through the visual observations that will be routinely conducted. Observations will be recorded on the Cover Material Inspection Form (See Appendix III). Observations will be made: daily by experienced landfill and treatment plant personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

3) Soil-like Material Laboratory Testing Requirements [N.J.A.C. 7:26- 2A.8(b)17]

For alternative cover materials that possess soil-like properties, the Department’s regulations specify additional laboratory testing depending on the nature of the material and its intended use as daily, intermediate of material. The required criteria are summarized below with the regulatory reference pursuant to N.J.A.C. (In Bold) followed by the evaluation technique proposed to assess the property (provided in Italics): i) 7:26-2A.8(b)17.i – The following tests are required for the proposed alternative daily cover:

• Solids Content; • Percent volatile solids; • Grain size analysis; and, • Moisture content

Response: The above-mentioned parameters are consistent with items under 7:26-2A.8(b)16 i through iv, previously addressed. The parameters will be measured by the GCUA in-house laboratory facility (solids content, percent volatile solids, and moisture content) and by a geotechnical consultant laboratory, (for grain size analysis). One (1) sample will be collected every week for in-house analysis. Grain size analysis will be performed once a month.

RD&D ANALYTICAL DATA LIMITATIONS

Traditional laboratory testing procedures do not always reflect the behavior and properties of the biosolids with respect to the purposes for which the above criteria were adopted by the Department. For instance, percent volatile solids are derived from a laboratory procedure that drives off all retained moisture and subjects the material to sustained temperatures of 550 degrees centigrade. Such a test method is not reflective of field scale conditions. It is the intent of this RD&D to consider analytical data in conjunction with full scale operations.

\\rve232\Groups\Facilities\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\residuals\RDD\Application\GCIA RD&D Application.docx | Page | 12 RD&D IMPLEMENTATION AND MANAGEMENT

The biosolids sludge derived product will be delivered by truck daily. The material will be unloaded near the active face of the landfill to facilitate application with a bulldozer or landfill compactor at the end of the day. All working areas of the landfill are underlain by an approved leachate collection system that will collect any liquid. The biosolids cover material will be utilized as cover at the end of the operating day. GCIA anticipates using the biosolids sludge derived product on a daily basis and will adjust daily deliveries to meet daily cover demands. The daily application of the biosolids, to be tested for use as an alternative daily cover, as part of the RD&D program will not exceed 100 tons/day.

BIOSOLIDS PRODUCT ACCEPTANCE/STORAGE

The product will be delivered by truck to the GCIA landfill on a 5 or 6 day per week basis and will be staged on an active portion of the landfill in close proximity to the working face (See Appendix V - Process Flow Diagram). GCIA does not envision a need for stockpiles.

DAILY COVER PLACEMENT

The material will be spread by use of a bulldozer or landfill compactor at the end of the day. All working areas of the landfill are underlain by an approved leachate collection system that will collect any liquid resulting. The biosolids cover material will be utilized as cover at the end of the operating day. GCIA proposes to place the biosolids sludge derived product as follows:

• As a daily cover material blended with o Soil cover o Approved alternative cover material o ID 27 contaminated soil o Automobile Shredder Residue (ASR) o Recycled Glass Aggregate (RGA)

The biosolids blended cover material will be placed and compacted to a minimum thickness of six (6) inches for use as daily cover. GCIA will apply the biosolids as a mixture with other authorized alternative cover material. The biosolids will be placed at the active working face of the landfill in close proximity to a sufficient volume of other cover materials to achieve a blend of not more than 1 part by volume of biosolids to 1 part other authorized alternative cover material. The respective cover materials will be pushed through and over each other by a bulldozer, landfill compactor or other equivalent equipment such that a mixture of or a patchwork of different materials will be evident in the applied daily cover (See Appendix V - Process Flow Diagram).

As discussed in previous sections of this application, observations of the performance of the biosolids and various blends of alternative cover material will be conducted and recorded by experienced landfill (GCIA) and wastewater treatment (GCUA) personnel, and Remington & Vernick Engineers (RVE). The GCIA landfill manager and staff are experienced in all aspects of landfill operations and maintenance. Observations with regard to adequacy of cover, presence of erosion, dust, ponding of water, odor, litter and fire are conducted on a continuous basis and, accordingly, distinctions or changes attributable to the use of biosolids blended cover material will be readily apparent and can be documented by the GCIA. GCIA maintains detailed records with respect to volumes and tonnage of all materials received at its landfill including alternative cover material. Volume and tonnage of biosolids used during the RD&D will be summarized from these records. In addition, GCIA maintains a weather station that can provide temperature wind and rainfall information.

RECORDKEEPING

A RD&D Cover Material Evaluation Form has been developed to record observations with regard to:

• Material properties and behavior • Type of alternative cover used for blending • Visual observations • Odor observations • Equipment/vehicle mobility • Difficulties encountered/recommendations • Photographs

The RD&D Cover Material Inspection Form is included in this application as Appendix III. The form may be adjusted or refined to provide additional assessment methods or to reduce recordkeeping burdens as the RD&D proceeds. In general, observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

LABORATORY TESTING

Laboratory testing will be performed for the parameters listed above in sections 7:26-2A.8(b)16i though iv and 7:26-2A.8(b) 17i. The parameters will be measured by the GCUA in-house laboratory facility (solids content, percent volatile solids, and moisture content) and by a geotechnical consultant laboratory (for grain size analyses).

The Gloucester County Solid Waste Complex is owned and operated by the Gloucester County Improvement Authority (GCIA). Located in South Harrison Township, the Solid Waste Complex is a sanitary landfill situated on a 540-acre tract of land. Currently the active landfill and supporting structures utilize 20 percent of the available area, the balance of the site remains undeveloped with parts used as a grassland bird habitat, for storm water management and a visual buffer. A Site Plan is included as Appendix I.

GCUA is seeking a modification to a Research Development and Demonstration (RD&D) application (Appendix IV), approved by the Department on April 11, 2018 (Appendix V). The current approval allows GCIA to evaluate the effectiveness of using an air entrained biosolid, enhanced through the Orege process, as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The biosolid is generated at the Gloucester County Utilities Authority (GCUA), a sister agency, as part of sludge handling during the wastewater treatment process and is being evaluated for use as alternative daily cover over a twelve-month (12) period by monitoring its use under varying operational and weather conditions. GCIA proposes to modify the RD&D application to include and evaluate two (2) additional biosolids for use as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The additional biosolids proposed to be evaluated include i) digested sludge, which is enhanced by the Orege process (air entrained) prior to dewatering, and ii) digested dewatered sludge. Existing and proposed plant process diagrams, identifying the three (3) biosolids streams are included as Appendix VI.

Should the RD&D provide favorable results, GCIA anticipates seeking longer term approval through a permit modification.

GCUA operates a Publicly Owned Treatment Works (POTW) to treat wastewater generated from domestic and industrial sources in the residential and commercial areas of southern New Jersey. The POTW is located at 2 Paradise Road, Thorofare, New Jersey, 08066 in West Deptford Township.

The GCUA continues to seek new beneficial use options to effectively manage the sludge generated at its facility. Significant cost savings may be possible through reduced transportation distances, logistics, and sludge management costs, if the biosolids generated at GCUA can be used beneficially at GCIA as an alternative daily cover. Besides cost reduction for GCUA, beneficial use of biosolids as daily cover at GCIA offers other potential benefits such as:

• Reduced need for traditional clean soil resources; • Lower cost to meet landfill cover needs; • Create a foundation for opportunities for using biosolids to fulfill cover needs at other landfills; and • Maintain the highest economic benefit of biosolids management within New Jersey.

In accordance with the Department’s Division of Solid & Hazardous Waste Regulations and Technical Manuals, the use of an alternative material for daily landfill cover must be approved as

Since biosolids is not a soil and is a non- traditional cover material, the Department provides that its use may be evaluated in accordance with the requirements for RD&D projects outlined in N.J.A.C. 7:26-2A.8(b)19.

Copies of the previous RD&D application, and Department approval is being submitted with this application as a reference.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 2 BACKGROUND AND PROJECT INFORMATION

NJDEP regulations applicable to the management of solid waste provide for an exemption from a full facility permit for RD&D projects to test and evaluate new or innovative technology or new innovative operational process modifications made to existing solid waste facilities or operations. The regulations, published at N.J.A.C. 7:26-1.7(f), require that a RD&D must be designed, constructed and operated consistent with applicable environmental statutes, rules, permits, approvals or orders.

PROJECT SPONSOR

GCIA is seeking a modification to an approved RD&D application, to include two (2) additional biosolids processes (in addition to the one (1) approved) and evaluate their effectiveness as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The 12-month project will assess the effectiveness of biosolids generated by three (3) treatment processes as an alternative cover material by monitoring their use under varying operational and weather conditions. Should the evaluation provide favorable results, GCIA anticipates seeking longer term approval through a permit modification. Accordingly, GCIA will serve as the project sponsor and applicant for the permit modification to utilize biosolids material as an alternative cover pursuant to Department requirements.

BIOSOLIDS PRODUCT GENERATOR INFORMATION

The GCUA wastewater treatment plant is in the process of upgrading their sludge handling process to produce an air-entrained, dewatered sludge product in the form of a biosolid. The enhanced biosolid is achieved due to conditioning thickened sludge using a proprietary Solid Liquid Gas (SLG) technology. The conditioned sludge will pass through a belt filter press for further dewatering, prior to it being transported for off-site disposal. The SLG technology is a patented process manufactured by Orege North America. The process increases cake dryness with a workable texture sludge reducing polymer usage and odor. The biosolids are air entrained prior to polymer addition and the belt filter press operation. The SLG technology will be installed upstream of one (1) dedicated belt filter press. Currently, this process is being used in Lehigh County, PA, where the sludge generated at the County’s wastewater treatment plant is conditioned with the SLG process and the biosolids produced are land applied to approximately one hundred (100) farms.

Concurrently, GCUA is in the process of upgrading its wastewater treatment process. Two (2) new anaerobic digesters are being built and will be operational later this year. As a result of unit process improvements, RVE would like to modify the existing RD&D application to include and evaluate two (2) additional biosolids for use as part of a blend with soil or other authorized alternative cover materials for use as a daily cover material. The additional biosolids proposed to be evaluated include i) digested sludge, which is enhanced by the SLG process prior to dewatering, and ii) digested dewatered sludge. An existing plant process diagram and a proposed plant process diagram, identifying the three (3) biosolids streams is included as Appendix VI.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 3 BIOSOLIDS PRODUCT STORAGE AND TRANSPORTATION

The dewatered sludge products are a recovered non-hazardous biosolids resource, classified Dry Sewage Sludge (waste type ID 12), per the NJDEP solid waste regulations as. The biosolid products will be stored at the GCUA until they can be beneficially reclaimed at the GCIA.

The dewatered biosolids will be conveyed from the discharge end of the belt filter press via a series of belt conveyors to a storage area at the GCUA. The storage area contains dedicated storage for holding and loading the biosolids. The three (3) proposed biosolid materials to be evaluated will be stored separate from each other and will not be mixed.

Under an existing contract between the sister agencies, GCUA will manage the transportation of the biosolid products to the GCIA. Truck routes will be consistent to those currently utilized by the GCUA when hauling incinerator ash to the GCIA. These are the same routes used in conveying GCIA leachate to the GCUA. Significant adverse impact to road traffic is not anticipated during the course of this RD&D.

ENVIRONMENTAL, ENGINEERING CONSULTING AND SUPPORT SERVICES

Environmental, engineering consulting and support services for this RD&D will be provided on behalf of the GCUA and the GCIA by Remington & Vernick Engineers (RVE). RVE has prepared the RD&D Application, proposed assessment, evaluation and reporting documents. RVE will provide oversight as necessary through the course of the RD&D to ensure that the terms of a RD&D approval issued by the NJDEP are implemented and that the RD&D findings are reported accurately. RVE shall serve the project as a team member along with the GCIA, GCUA, and NJDEP.

BACKGROUND

Although sludge derived biosolid products have been successfully used in New Jersey and other states as landfill cover material, a complete demonstration of how the GCUA material will meet NJDEP’s regulatory requirements applicable to cover material has not been completed in a formal assessment report. NJDEP’s regulations and technical guidance manuals allow for appropriately permitted solid waste landfill facilities to seek approval for alternative landfill cover materials. The regulations establish many behavioral, physical and analytical criteria for alternative cover materials and set forth landfill permit modification applications guidelines. For non-traditional landfill cover materials which may not possess soil-like properties, the Department provides that the cover material may be evaluated in accordance with the requirements for RD&D projects (see N.J.A.C. 7:26-2A.8(b)15-19.

The RD&D regulations published at N.J.A.C. 7:26-1.7(f)4 require that a RD&D project shall be included by administrative action within the district solid waste management plan for the county or district within which the project is located on the Statewide Solid Waste Management Plan.

GCIA has filed an application with the NJDEP to amend the Certified District Solid Waste Management Plan for the County of Gloucester in accordance with the NJDEP regulations for solid waste planning (N.J.A.C. 7:26-6.11). The Administrative Action Application allows the receipt by the GCIA at its permitted landfill in South Harrison Township of biosolids sludge derived product (waste Type 12) generated by the GCUA at its POTW in West Deptford Township, New Jersey for the purpose of testing for use as alternative landfill cover material in accordance with terms of any approval that may be issued by the NJDEP pursuant to the Department’s landfill and/or RD&D regulations.

OBJECTIVES

The objective of the RD&D application is to evaluate the effectiveness of utilizing digested and dewatered sludge as an alternative daily cover when used in combination with other approved daily cover materials at GCIA. Additionally, two (2) other biosolids materials generated at GCUA and enhanced by using a proprietary Solid Liquid Gas (SLG) process manufactured by Orege North America, are proposed to be evaluated as part of the project.

The SLG technology is currently used to treat sludge from a wastewater treatment facility in Lehigh County, PA to generate biosolids that are then applied as alternative daily cover at the County Landfill. GCIA believes that the technology can be successfully applied to the sludge generated at GCUA and the biosolids sludge derived product can be used as a blend with other authorized alternative cover materials at the GCIA landfill. The RD&D project aims to successfully demonstrate the compliance of the GCUA biosolids with sanitary landfill daily cover performance requirements as outlined in New Jersey’s landfill regulations. These regulations require that a landfill cover:

• Adequately cover the waste fill;

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 6 • Impede the entry of rodents and vectors into the waste fill; • Control malodorous emissions from the waste fill; • Provide a fire break; • Resist water erosion; • Resist wind erosion; and • Reduce the occurrence of windblown litter.

Visual inspection of the air entrained biosolids generated from the SLG process do not exhibit any limiting factors that might prevent its use as alternative daily cover. GCIA believes that the alternative cover material will allow the percolation of rain and snow melt to readily pass through the landfill profile and reach the leachate collection system with little to no potential for leachate outcrops to form at the landfill surface. GCIA does not anticipate any pressure buildup due to accumulation of landfill gases under the biosolids. Generally, the biosolids will exhibit all characteristics that are typical of soil that is used as daily cover.

BIOSOLIDS PRODUCT PHYSICAL AND ANALYTICAL PROPERTIES

The biosolids product is dewatered sludge produced as part of the wastewater treatment process and may be conditioned with the SLG technology at GCUA’s sewage treatment facility in West Deptford Township. The material is a non-hazardous material in accordance with NJDEP 2015 Residential Standards classification requirements. The moisture content can vary, but is typically between 70 to 80 percent by weight. The material has a mild musty soil like odor.

SCOPE

GCIA proposes that the approved RD&D be modified and authorized for a period of one (1) year between October 2018 through September 2019. This will provide for a thorough assessment of the three (3) biosolids materials as a blend with other materials to meet the requirements of daily cover material in accordance with the procedures outlined herein. GCIA proposes to accept less than 100 tons per day (all three (3) biosolids stream combined) of the biosolids sludge derived products to be tested for use as alternative landfill cover material. Daily delivery volume and tonnage will be monitored and adjusted by GCIA as needed based on availability and delivery of authorized alternative cover material for blending with the biosolids. The product will be delivered to the GCIA landfill on a 5 or 6 day per week basis, on an active portion of the landfill in close proximity to the working face. GCIA does not envision a need for stockpiles. Material will be delivered only during operational hours in accordance with GCIA’s landfill permit. The biosolids sludge derived landfill cover product can be applied with traditional landfill operational equipment as blended material mixed with soil or other authorized alternative cover material such as ID 27 contaminated soil or Automobile Shredder Residue (“ASR”) or Recycled Glass Aggregate (“RGA”). The material can be spread with a bulldozer, landfill compactor or equivalent earth handling equipment. The material will be applied and compacted to a minimum thickness of six (6) inches as a mixture that is blended or interspersed with soil or other authorized alternative cover material. The respective cover materials will be pushed through and over each other, in the prescribed ratios, by a bulldozer, landfill compactor or other equivalent equipment such that a mixture of or a patch work of different materials will be evident in the applied cover. The amount of biosolids material to be applied in alternative cover blends will be limited to a maximum of

RD&D DEMONSTRATION REQUIREMENTS

The required criteria and requirements that need to be met for the RD&D testing are summarized below. For ease of reference, the criteria are typed in bold. The material properties that GCIA believes provides the requisite control and the evaluation technique proposed to assess the property follows in Italics.

1) Alternative Landfill Cover Requirements [N.J.A.C. 7:26-2A.8(b)15]

In accordance with NJDEP landfill regulations N.J.A.C. 7:26-2A.8(b)7, all exposed surfaces of solid waste shall be covered at the close of each operating day with a daily cover consisting of six inches of compacted clean soil or alternative cover material subject to the approval of the Department. Any alternative cover material must meet the guidance as set forth in the Department’s “Technical Manual for Cover Material Requests” and meet the following criteria as outlined in N.J.A.C 7:26-2A.8(b)15: i) 7:26-2A.8(b)15.i – The alternative material must impede the entry of rodents and vectors into the waste fill;

Response: The biosolids landfill cover product applied as a blended material mixed with soil or other authorized alternative cover material will provide a barrier to impede the entry of rodents and vectors into the compacted waste material.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 8 Assessment of Performance: Observations will be conducted by visual observation and will be documented as needed by photographs of the application of the product and/or blended material. Observations for rodent activity or visible burrows will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager: and semi-monthly by RVE. Notation of observations will be recorded on the cover material inspection form (see Appendix II) by the landfill manager and RVE during observations. If landfill personnel identify any evidence of rodent activity or habitat, same will be made known to the landfill manager and RVE. ii) 7:26-2A.8(b)15.ii – The alternative material must control malodorous emissions;

Response: The minimum thickness of the biosolids and blended material to be used as alternative daily cover will be at least six (6) inches so as to assist in the mitigation of excessive release of solid waste odors. The biosolids developed through the SLG solution technology treatment process will be aerated, thereby reducing typical sewage sludge odors. The biosolids emit a slight musty soil like odor.

Assessment of Performance: Observations will be conducted by sense of smell and will be recorded on the Cover Material Inspection Form (See Appendix II) by the landfill manager and RVE during observations. Odor observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager: and semi-monthly by RVE. If landfill personnel identify any offensive odor emission, it will be brought to the attention of the landfill manager and RVE. iii) 7:26-2A.8(b)15.iii – The alternative material must provide a firebreak;

Response: The occurrences of fires at well managed landfills are rare. The disposal and compaction of waste material in controlled lift thicknesses that are covered to provide a structural separation of waste materials coupled with the implementation of engineered landfill gas controls has virtually eliminated landfill fire potential. The biosolids alternative cover blend material will provide a structural separation to compacted waste layers or lifts thus providing a physical fire break. The delivered biosolids product has a moisture content of approximately 70 to 80 percent that will aid in the prevention of fires and migration of fire should one occur. This moisture content in conjunction with proper solid waste lift construction and proper management of landfill gases will provide protection against the occurrence of landfill fires.

Assessment of Performance: Observations will be conducted visually and by sense of smell for any evidence of excessive temperature, smoke, or fire. Observations will be recorded on the Cover Material Inspection Form (See Appendix II). Observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 9 iv) 7:26-2A.8(b)15.iv – The alternative material must resist erosion;

Response: The biosolids material has similar physical properties to soil and many traditionally accepted alternative landfill cover materials. The fibrous nature of the product and polymers added as part of the treatment process add binding properties to resist the effects of water erosion.

Assessment of Performance: Observations will be conducted and documented as needed by photographs of alternative cover material following exposure to significant rain events. Observations for visible erosion will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi- monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix II) by the landfill manager and RVE. Additional observation frequency will be as needed following rain events or if landfill personnel identify any increased evidence of stormwater erosion. v) 7:26-2A.8(b)15.iv – The alternative material must not be easily windblown;

Response: The biosolids have a moisture content of approximately 70 to 80 percent which aids in the prevention of dust attributable to biosolids covered areas. Although dust caused by windblown fine particles of soil and alternative cover material can occur during extremely dry and high wind conditions even at well managed sanitary landfill facilities, it is expected that the moisture content of the subject biosolids will minimize this condition.

Assessment of Performance: Observations will be conducted for dust and will be documented as needed by photographs (if possible) of dust emanating from biosolids covered areas. The schedule of observations for dust will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix II). If landfill personnel identify any dust presence relating to the biosolids, it will be brought to the attention of the landfill manager and RVE. vi) 7:26-2A.8(b)15.v – The alternative material must control windblown litter;

Response: Windblown litter is a common occurrence at sanitary landfills; routine litter cleanup must always be conducted. The biosolids material has similar physical properties to soil and many traditionally accepted alternative landfill cover materials and should provide an effective control measure to mitigate the occurrence of windblown waste material similar to that provided by traditional daily cover material.

Assessment of Performance: Observations will be conducted for increased evidence of windblown litter and will be documented as needed by photographs when there is a determination that the litter emanated from areas subject to biosolids cover under the RD&D pilot testing program. The initial schedule of

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 10 observations for litter will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE. Notations of observations will be recorded on the Cover Material Inspection Form (See Appendix II). If landfill personnel identify any increased evidence of litter attributable to biosolids covered areas, the landfill manager and RVE will be notified.

2) Alternative Cover Performance Requirements [N.J.A.C. 7:26-2A.8(b)16]

For purposes of assuring material manageability, preventing contaminated surface water runoff, allowing the controlled venting of landfill gases and, reducing the occurrence of fires, NJDEP has published regulatory criteria for the percent of combustible and material grain size distribution. We note that several of the purposes mirror the requirements of those set forth at N.J.A.C. 7:26- 2A.8(b)15 and can be evaluated in the manner detailed in the proposed performance assessments in section 1 above. The required criteria are summarized below with the regulatory reference pursuant to N.J.A.C. followed by the material properties we believe provide the requisite control and the evaluation technique proposed to assess the property. i) 7:26-2A.8(b)16.i – The volatile solids or combustible content of the cover shall not exceed 12 percent by weight;

Response: Historically GCUA blended solids have been tested for total solids and volatile solids on a daily basis. This material averages 4.5% total solids with volatile solids comprising 78-82%. It is anticipated that the SLG air-entrained biosolids used as daily cover will be dewatered to 20-30% total solids by weight, while the remaining 70 to 80% of the product will be liquid. The dewater biosolids will be used in a 1:1 blend by volume with other approved daily cover. Accounting for the blend, the percent by weight of volatile solids is not expected to exceed 12%.

Assessment of Performance: GCUA will conduct daily analytical for total solids and volatile solids of the biosolids product at their in-house laboratory facility throughout the course of the RD&D. Also, GCUA will conduct an analytical of total solids and volatile solids of the GCIA daily cover material prior to blending with the biosolid, along with a measurement of SLG air-entrained biosolids density to convert from volume to weight for calculations. The results and calculations will be provided as part of a final report submitted at the conclusion of the RD&D. ii) 7:26-2A.8(b)16.ii – No more than 20 percent of fine grained materials shall pass No. 200 sieve;

Response: Use of biosolids as an individual daily cover material or in combination with soil or other authorized alternative cover material as a daily cover material will meet the underlying intent of this particle size standard.

• To prevent the formation of impervious vertical barriers to the downward flow of leachate that may lead to leachate outcrops and potential offsite discharge of leachate as stormwater.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 11 • To prevent vertical barriers to the upward flow of landfill gas that may lead to lateral migration of potentially explosive or flammable gases from the landfill property. • To provide filtration or adsorption of potentially odorous gases that vent to the landfill surface to reduce off-site odor impacts. • To reduce wind and water erosion of fine grained particles of cover material that can contribute to dust emissions in air and sediment transport to surface water. Accordingly, the final condition of the biosolids cover will allow leachate to easily percolate through the landfill profile and reach the leachate collection system with little to no potential for leachate outcrops to form at the landfill surface. Likewise, landfill gases will permeate the biosolids at a rate that will prevent undue pressure build up. The structure and moisture retention properties of the biosolids will promote the adsorption of odorous compounds that may be entrained in the landfill gas.

Assessment of Performance: The GCUA, in cooperation with the GCIA, have completed particle size distribution analyses on a variety of biosolids materials with results presented in the Analytical Report dated 11/25/15, Appendix III. The analyses evaluated the impact of digestion, dewatering, and drying on the grain size distribution of a biosolid. The results showed the biosolids met the gradation restrictions of > 40% passing a #10 sieve and < 20% passing a #200 sieve, regardless of processing techniques.

During the RD&D, a particle size distribution analysis will be conducted on the biosolids material for use as daily cover once a month. iii) 7:26-2A.8(b)16.iii - At least 40 percent by weight of the fragments in the soil admixture shall be capable of passing through a No. 10 mesh sieve;

Response: The underlying intent of this criteria is to avoid the use of extremely coarse grained materials such as gravel and stone so as to reduce the volume of voids. Coarse grained materials when used as daily cover can lead to offsite migration of landfill gases as the gas can readily escape through the voids into the atmosphere.

Response: Particles are limited in size to six (6) inches, which is consistent with the minimum depth of cover. Soils up to six (6) inches are classified as silts, sands, and small gravels. Combinations of these classifications will work on-site to provide structure and integrity to the layer of daily cover.

Assessment of Performance: The presence of large particles within the biosolids product can be determined from visual observation of delivered material as well as during the biosolids loading procedure at GCUA.

Biosolids when spread is not anticipated to result in particle sizes approaching six (6) inches. The presence or absence of large particles can be determined through the visual observations that will be routinely conducted. Observations will be recorded on the Cover Material Inspection Form (See Appendix II). Observations will be made: daily by experienced landfill and treatment plant personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

3) Soil-like Material Laboratory Testing Requirements [N.J.A.C. 7:26- 2A.8(b)17]

For alternative cover materials that possess soil-like properties, the Department’s regulations specify additional laboratory testing depending on the nature of the material and its intended use as daily, intermediate of final cover material. The required criteria are summarized below with the regulatory reference pursuant to N.J.A.C. (In Bold) followed by the evaluation technique proposed to assess the property (provided in Italics): i) 7:26-2A.8(b)17.i – The following tests are required for the proposed alternative daily cover:

• Solids Content; • Percent volatile solids; • Grain size analysis; and, • Moisture content

Response: The above-mentioned parameters are consistent with items under 7:26-2A.8(b)16 i through iv, previously addressed. The parameters will be measured by the GCUA in-house laboratory facility (solids content, percent volatile solids, and moisture content) and by a geotechnical consultant laboratory, (for grain size analysis). One (1) sample will be collected every week for in-house analysis. Grain size analysis will be performed once a month.

RD&D ANALYTICAL DATA LIMITATIONS

Traditional laboratory testing procedures do not always reflect the behavior and properties of the biosolids with respect to the purposes for which the above criteria were adopted by the Department. For instance, percent volatile solids are derived from a laboratory procedure that drives off all retained moisture and subjects the material to sustained temperatures of 550 degrees centigrade.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 13 Such a test method is not reflective of field scale conditions. It is the intent of this RD&D to consider analytical data in conjunction with full scale operations.

T:\Water\Facilities06on\NJ Gloucester\0800M GCUA\0800M046 Digester\Permits\Residuals\RDD - Revised 082718\Application\Report\GCIA RD&D Application.docx | P a g e | 14 RD&D IMPLEMENTATION AND MANAGEMENT

The biosolids sludge derived product will be delivered by truck daily. The material will be unloaded near the active face of the landfill to facilitate application with a bulldozer or landfill compactor at the end of the day. All working areas of the landfill are underlain by an approved leachate collection system that will collect any liquid. The biosolids cover material will be utilized as cover at the end of the operating day. GCIA anticipates using the biosolids sludge derived product on a daily basis and will adjust daily deliveries to meet daily cover demands. The daily application of the biosolids, to be tested for use as an alternative daily cover, as part of the RD&D program will not exceed 100 tons/day.

BIOSOLIDS PRODUCT ACCEPTANCE/STORAGE

The products will be delivered by truck to the GCIA landfill on a 5 or 6 day per week basis and will be staged on an active portion of the landfill in close proximity to the working face (See Appendix VI - Process Flow Diagram). GCIA does not envision a need for stockpiles.

DAILY COVER PLACEMENT

The material will be spread by use of a bulldozer or landfill compactor at the end of the day. All working areas of the landfill are underlain by an approved leachate collection system that will collect any liquid resulting. The biosolids cover material will be utilized as cover at the end of the operating day. GCIA proposes to place the biosolids sludge derived product as follows:

• As a daily cover material blended with o Soil cover o Approved alternative cover material o ID 27 contaminated soil o Automobile Shredder Residue (ASR) o Recycled Glass Aggregate (RGA)

The biosolids blended cover material will be placed and compacted to a minimum thickness of six (6) inches for use as daily cover. GCIA will apply the biosolids as a mixture with other authorized alternative cover material. The biosolids will be placed at the active working face of the landfill in close proximity to a sufficient volume of other cover materials to achieve a blend of not more than 1 part by volume of biosolids to 1 part other authorized alternative cover material. The respective cover materials will be pushed through and over each other by a bulldozer, landfill compactor or other equivalent equipment such that a mixture of or a patchwork of different materials will be evident in the applied daily cover (See Appendix VI - Process Flow Diagram).

As discussed in previous sections of this application, observations of the performance of the biosolids and various blends of alternative cover material will be conducted and recorded by experienced landfill (GCIA) and wastewater treatment (GCUA) personnel, and Remington & Vernick Engineers (RVE). The GCIA landfill manager and staff are experienced in all aspects of landfill operations and maintenance. Observations with regard to adequacy of cover, presence of erosion, dust, ponding of water, odor, litter and fire are conducted on a continuous basis and, accordingly, distinctions or changes attributable to the use of biosolids blended cover material will be readily apparent and can be documented by the GCIA. GCIA maintains detailed records with respect to volumes and tonnage of all materials received at its landfill including alternative cover material. Volume and tonnage of biosolids used during the RD&D will be summarized from these records. In addition, GCIA maintains a weather station that can provide temperature wind and rainfall information.

RECORDKEEPING

A RD&D Cover Material Evaluation Form has been developed to record observations with regard to:

• Material properties and behavior • Type of alternative cover used for blending • Visual observations • Odor observations • Equipment/vehicle mobility • Difficulties encountered/recommendations • Photographs

The RD&D Cover Material Inspection Form is included in this application as Appendix II. The form may be adjusted or refined to provide additional assessment methods or to reduce recordkeeping burdens as the RD&D proceeds. In general, observations will be made: daily by experienced landfill personnel; weekly by the GCIA landfill manager; and semi-monthly by RVE.

LABORATORY TESTING

Laboratory testing will be performed for the parameters listed above in sections 7:26-2A.8(b)16i though iv and 7:26-2A.8(b) 17i. The parameters will be measured by the GCUA in-house laboratory facility (solids content, percent volatile solids, and moisture content) and by a geotechnical consultant laboratory (for grain size analyses).

Re: Modified Certificate of Authority to Operate an RD&D Project Gloucester County Improvement Autl;tority Landfill South Harrison Township, Gloucester County PI# 132199 Certificate No. CT0180001

Dear Mr. Sullivan:

The Bureau of Solid Waste Permitting (Bureau) is in receipt of a letter dated September 4, 2018, submitted by Dennis K. Yoder of Remington & Verni ck Engineers on behalf of Gloucester County Utilities Authority (GCUA) and the Gloucester County Improvement Authority (GCIA), requesting a modification to the Research, Development and Demonstration (RD&D) Approval dated April 11, 2018 for the evaluation of biosolids at the referenced landfill. The purpose of the proposed modification to the RD&D project is to evaluate the effectiveness of two additional biosolids generated by GCUA as alternative daily cover material.

The Bureau has reviewed the request and understands that GCUA is in the process of upgrading its waste water treatment process. Two new anaerobic digesters were built and became . operationaUn January 2018. Following the initiation of an process, GCUA has also been experimenting by eliminating and/or replacing parts of the Orege process to control moisture content and reduce the plasticity of the. biosolids. While experimenting GCUA continued to supply biosolids meeting the alternative daily cover criteria to facility.

The Bureau has reached a final decision to approve the request to conduct the RD&D proj.ect using the two additional biosolids and is issuing the enclosed Certificate of Authority to Operate (CAO) under the authority in the Solid Waste Regulations at N.J.A.C. 7:26-l.7(f). Conditions have been incorporated within the CAO that must be complied with. The CAO is valid for one year from the issuance date. Should the evaluation program prove that the material meets the performance standards as set forth in N.J.A.C. 7:26-2A.8(b)15 and you wish to continue using the biosolids as an alternative cover beyond the expiration date of this approval, an application

The State of New Jersey is an equal opportunity employer. Printed on recycled and recyclable paper. for a modification to GCIA's solid waste facility permit must be submitted and approved by the Bureau.

If you have any questions concerning this matter, please contact Sanjay Shah of my staff by telephone at 609-984-6599, or by email at [email protected].

Very truly yours, a~ dG"X~~· Anthony ~a, Chief Bureau of Solid Waste Permitting
