ENVIRONMENTAL ASSESSMENT WORKSHEET

Note to reviewers: The Environmental Assessment Worksheet (EAW) provides information about a project that may have the potential for significant environmental effects. This EAW was prepared by the Minnesota Pollution Control Agency (MPCA), acting as the Responsible Governmental Unit (RGU), to determine whether an Environmental Impact Statement (EIS) should be prepared. The project proposer supplied reasonably accessible data for, but did not complete the final worksheet. Comments on the EAW must be submitted to the MPCA during the 30-day comment period which begins with notice of the availability of the EAW in the Minnesota Environmental Quality Board (EQB) EQB Monitor. Comments on the EAW should address the accuracy and completeness of information, potential impacts that are reasonably expected to occur that warrant further investigation, and the need for an EIS. A copy of the EAW may be obtained from the MPCA by calling 651-757-2101. An electronic version of the completed EAW is available at the MPCA website at http://www.pca.state.mn.us/news/eaw/index.html#open-eaw. 1.

6. Description:

a. Provide a project summary of 50 words or less to be published in the EQB Monitor. Randy’s Sanitation (hereinafter Randy’s or proposer) is proposing to increase the permitted capacity of their existing solid waste transfer and recycling station located in the city of Delano, Wright County, Minnesota. The facility is currently permitted to accept a maximum of 78,250 tons per year (tpy), or approximately 244,000 cubic yards (cy) per year of mixed municipal solid waste (MSW) and construction and demolition debris (C&D). The amount is equal to approximately 350 tons per day (tpd). The facility is requesting to increase permitted capacity to accept up to 125,000 tpy (375,000 cy) of MSW and C&D, with a maximum of 550 tpd.

b. Give a complete description of the proposed project and related new construction. Attach additional

sheets as necessary. Emphasize construction, operation methods and features that will cause physical manipulation of the environment or will produce wastes. Include modifications to existing equipment or industrial processes and significant demolition, removal or remodeling of existing structures. Indicate the timing and duration of construction activities. Randy’s is a waste hauling and collection business that currently operates in multiple counties within and surrounding the Twin Cities Metropolitan Area. Randy’s contracts with residential, contractor, and commercial operations for the hauling of solid waste and recyclables to approved waste management facilities and recyclables markets throughout the region. Randy’s owns and operates a solid waste transfer and recycling facility located in the city of Delano, Minnesota (Figure 1), which is the location of the proposed project site. Access to the site is from U.S. Highway 12. The facility is located on a 21-acre parcel of land owned by Randy’s. Nine acres of the parcel is used for facility operations, including corporate offices, vehicle maintenance, and the solid waste transfer and recycling operations building. The remaining portion of the property is undeveloped grassland and wetland. In 2000, the facility was approved by Wright County and the MPCA for construction and operation as a solid waste transfer and recycling facility under Randy’s ownership. The facility has a county solid waste license under Randy’s ownership, as well as MPCA Solid Waste Permit SW-578. In 2005, the MPCA approved modification to the MPCA permit to increase daily waste capacity, management of source separated organics, and capacity of source separated recyclable materials. The current MPCA solid waste permit allows for the transfer of a combined maximum of 78,250 tpy (350 tpd) of MSW, which includes source separated organic material, industrial waste, as outlined in the approved industrial waste management plan, and C&D. The permit also authorizes Randy’s to accept and transfer up to 5,500 tpy of yard waste. Randy’s is also authorized to process and transfer up to 2,010 cy of recyclables at the site at any one time, which includes but is not limited to source separated organic materials, white goods (appliances including, but not limited to, refrigerators, ranges, washers and

dryers), electronics, and tires. The existing recyclables capacity does not include source separated organics and recyclables stored in enclosed containers and enclosed trailers on site. It only applies to those recyclables stored within the recycling portion of the transfer building. The purpose of the proposed capacity expansion is to increase the amount of MSW and recyclables that can be processed and stored before transfer to a waste management disposal facility. The solid waste transfer and recycling building includes the use of automated compaction and loading equipment in the transfer station portion of the facility and automated baling and processing equipment in the recycling portion of the facility. MSW and recyclables are delivered to tipping floor areas, where it is weighed and sorted for processing. This includes organic waste collected and delivered in specially designed blue bags. Collection vehicles back into the building through overhead doors. The overhead doors are 18 feet wide by 26 feet high. The tipping areas consist of a 6-inch thick, reinforced concrete floor and concrete push walls. Currently, waste is fed into a conveyor pit by a front-end loader. All acceptable waste is transferred onto a conveyor that moves the waste into a compactor, and then loaded into transport vehicles. The transport vehicles transfer the waste for disposal at an authorized waste management disposal facility, such as Elk River Landfill in Sherburne County, or the Spruce Ridge Landfill in Glencoe, Minnesota. Incoming unacceptable waste is screened and removed for proper disposal. Screening of the incoming MSW involves spreading the waste loads on the tipping floor and visually inspecting the waste for unacceptable items, such as paint cans, large electronics, and unknown or hazardous maters. These unacceptable items are removed from the tipping flow. Depending on the items, the waste hauler may take them back or Randy’s may assess the hauler a fee for proper disposal. Hazardous or unknown materials are placed in a specifically designed hazardous materials room at the facility. The hazardous materials room is lined with a grated floor, which allows any spills to be contained, and routed to two tanks located below the tipping flow. Solids captured are sent to Veolia ES Rolling Hills Landfill in Wright County, and liquids are periodically pumped and hauled to the Metropolitan Council Environmental Services (MCES) Metro Wastewater Treatment Facility (WWTF) in St. Paul, Minnesota, for treatment and disposal. There are several separate entities that contract with Randy’s to dispose of unacceptable items. A separate entity is used for each of the following unacceptable waste items: “sharps” (e.g., needles), electronics, appliances, light bulbs, and hazardous or unknown materials. Some of the entities pick up the items from the Randy’s facility, while other entities require Randy’s to haul unacceptable waste, such as appliances and electronics, to a different location for processing. The facility uses a materials recovery facility (MRF) to process single-stream recycling. In the recycling tipping floor area, waste is fed into the MRF starting with picking stations and a trammel screen. The recycling system used at the facility is mainly single-stream although dual-stream loads would be handled. Single-stream recycling (also known as fully commingled) refers to a system in which all paper and containers are mixed together. Dual-stream refers to separation into individual commodities (newspaper, cardboard, plastics, glass, etc.) or commingled into two streams (paper and containers). Waste and recyclables are processed through the use of equipment to presort incoming waste material with the intent of removing certain wastes and recyclables. This is accomplished through the use of conveyors; trammel screen for removal of fines, such as sand, grit, broken glass, etc.; eddy current separator for collection of aluminum; magnet for collection of ferrous material; and picking station for manual removal of plastic and corrugated material. Recyclable materials are baled, and then transferred for further management and/or sold to existing markets. The sale of recyclable materials is market driven

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 4 Worksheet

and, therefore, the price and types of materials that are sold varies greatly. Randy’s works with potential buyers to determine a fair market rate for recyclable materials, such as paper, aluminum, and steel. These materials are baled and sold at the going market rate to respective buyers for reuse in other products. Minimal quantities of recyclable materials not sold immediately are transferred to storage containers and stored on site until the market for those materials dictates selling. Randy’s does not store large quantities of recyclables and typically only stores materials for short durations of time, as the market for these materials tends to be steady. Randy’s has started a new program called Blue Bag Organics. This program allows Randy’s customers to use specially designed bags to dispose of their compostable waste, such as food scraps and soiled paper products. The blue bags are picked up by Randy’s haulers with the regular household MSW. At the facility, the blue bags are manually separated from the waste stream, and then hauled to another company that converts the bags and material into compost for resale to local retail markets. Randy’s customers have the option to receive a certain quantity of this compost Proposed Expansion Randy’s is proposing to increase the maximum annual MSW processing capacity at the facility from 78,250 tpy (244,000 cy) to 125,000 tpy (375,000 cy). The facility is currently a recycling facility and not a waste processing facility. The proposed project, which includes the installed additional MRF equipment, would allow the facility to provide a single-stream recycling and greater waste processing capabilities. The Proposer is also requesting additional permitted capacity to store recyclables, up to 3,500 cy at the site at any one time as defined in the permit as those recyclables stored within the transfer building. It does not include those stored in enclosed containers on site. The anticipated outcome is that approximately 65 percent of the MSW coming into the facility would be processed and recycled in some way, leaving approximately 35 percent remaining that would ultimately end up at a landfill. The facility has recently been modified to accommodate additional capacity by adding additional tipping floor space. MRF processing equipment is scheduled to be added in summer of 2012. Randy’s has submitted a construction certification report to the MPCA for review and approval. No further changes to the existing facility structures are proposed.

c. Explain the project purpose; if the project will be carried out by a governmental unit, explain the need

for the project and identify its beneficiaries. The purpose of the project is to increase the operational capacity of the existing facility. The project is not being carried out by a governmental unit.

d. Are future stages of this development including development on any other property planned or likely to happen? Yes No At this time, there are no plans for future stages of development on the project site or on any other property.

e. Is this project a subsequent stage of an earlier project? Yes No

There has been no previous environmental review completed for the existing facility, which began construction and operation in 2000.

The facility is located along the US Highway 12 corridor. There are a number of commercial and industrial businesses located to the east and south of the facility. West of the facility is undeveloped wetlands that are part of Randy’s property. Directly adjacent to the north is a 20-acre parcel that is primarily undeveloped, but is used as a commercial business, including a building on its north side. Property located between the facility and US Highway 12 to the east is also undeveloped, but zoned by Wright County as Highway Business (B-1). Further discussion on zoning and local plans is provided in Item 27. There are several commercial businesses located directly across US Highway 12 from the facility that are within the city limits of Delano. There are also commercial businesses located to the south of the facility that are part of Franklin Township, which is under Wright County zoning authority. There are no known past or current environmental hazards, such as abandoned storage tanks, soil contamination or hazardous liquids, located on or adjacent to the project site. Randy’s has a hazardous waste generator license for small quantities of hazardous waste that is collected during MSW processing. Additional discussion on MSW processing is provided in Item 20. The proposed project would allow the facility to process additional MSW and recyclables, which would be compatible with existing land uses on and adjacent to the facility.

10. Cover Types. Estimate the acreage of the site with each of the following cover types before and after development:

Before After Before After Types 1-8 wetlands 8.67 8.67 Lawn/landscaping 2.34 2.34 Wooded/forest 0 0 Impervious Surfaces 7.88 7.88 Brush/grassland 1.56 1.56 Stormwater pond 0.34 0.34 Cropland 0 0 Other (describe) TOTAL 20.76 20.76 11. Fish, Wildlife, and Ecologically Sensitive Resources. a. Identify fish and wildlife resources and habitats on or near the site and describe how they would

be affected by the project. Describe any measures to be taken to minimize or avoid impacts. The proposed project would occur at an existing facility in an area that has been previously impacted by development and is currently impervious surface. There are no anticipated impacts on wildlife habitat on the site.

b. Are any state (endangered or threatened) species, rare plant communities or other sensitive ecological resources on or near the site? Yes No The Minnesota Department of Natural Resources (DNR) was requested to query their Natural Heritage Information System database to determine if any state-listed species, rare plant communities or other sensitive ecological resources occur on or near the project site. The query includes areas within an approximately one-mile radius of the facility. The results of that query, dated January 11, 2012, indicate there are no known occurrences of rare features in the search area, and no impacts to sensitive resources would occur from the proposed project.

12. Physical Impacts on Water Resources. Will the project involve the physical or hydrologic alteration (dredging, filling, stream diversion, outfall structure, diking, and impoundment) of any surface waters such as a lake, pond, wetland, stream or drainage ditch? Yes No

The proposed project would not impact water resources. Randy’s obtained an NPDES/SDS Construction Stormwater Permit for the construction of the facility’s tipping expansion, approximately 7,000 square feet, which occurred in the fall of 2011 and went into early 2012. For this permit, a construction Stormwater Pollution Prevention Plan (SWPPP) was used to ensure that best management practices (BMPs) and other requirements were followed for the duration of construction. The facility also operates under an NPDES/SDS General Industrial Stormwater Permit, as listed under Item 8 of this EAW. This permit requires the facility to follow BMPs and other requirements outlined in the facility’s SWPPP during operation. See also Item 17.

13. Water Use. Will the project involve installation or abandonment of any water wells, connection to or changes in any public water supply or appropriation of any ground or surface water (including dewatering)? Yes No The facility is connected to the city of Delano water, which it uses primarily for domestic purposes, including vehicle maintenance. The proposed project would not change the quantity or use of water at the facility.

14. Water-related land use management districts. Does any part of the project involve a shoreland zoning

district, a delineated 100-year flood plain, or a state or federally designated wild or scenic river land use district? Yes No Floodplain maps and shoreland zoning maps were reviewed, which indicated that the project site is not located within a water-related land use management district.

15. Water Surface Use. Will the project change the number or type of watercraft on any water body? Yes No

If yes, indicate the current and projected watercraft usage and discuss any potential overcrowding or conflicts with other uses. Not applicable.

16. Erosion and Sedimentation. Give the acreage to be graded or excavated and the cubic yards of soil to be moved: 0 acres; 0 cubic yards. Describe any steep slopes or highly erodible soils and identify them on the site map. Describe any erosion and sedimentation control

measures to be used during and after project construction. The proposed project would not require construction or alterations of existing structures or property, therefore no impacts to water resources are expected. Please refer to Item 12 of this EAW for information regarding additional equipment for the MRF building and facility construction and Industrial Stormwater Permits.

17. Water Quality – Surface-water Runoff. a. Compare the quantity and quality of site runoff before and after the project. Describe permanent

controls to manage or treat runoff. Describe any storm-water pollution prevention plans. Because there are no new structures or construction proposed at the facility, the proposed project is not expected to change the quantity or quality of stormwater runoff. The site is covered primarily by impervious surfaces. The impervious features include the main entrance, the driveways, parking spaces, and buildings. The pervious surfaces include the landscaped areas along U.S. Highway 12, landscaped areas around the parking lot for the main offices, the stormwater pond and a small gravel area where dumpsters are stored. The site generally slopes from the transfer station building to the south. The majority of the stormwater is collected by catch basins throughout the paved driveways and parking area and is directed to a stormwater pond, located in the southwest corner of the site (Figure 3). An overflow outlet is located in the northwest corner of the stormwater pond. If the pond does overflow, the water is directed to the adjoining wetland to the west within the property boundary of the facility.

Roof drains from the buildings are also connected to the stormwater infrastructure. Near the transfer building, two trench drains at the loading docks of the transfer station and four stormwater catch basins are connected to an outlet structure that drains to the wetland area (Figure 3). Randy’s is required to obtain and operate in accordance with Minnesota’s Multi-Sector General Stormwater Permit (General Permit). An SWPPP was prepared in March 2011 as a required component of the General Permit. The General Permit is an authorization to discharge stormwater associated with industrial activity under the NPDES/SDS Permit Program. The General Permit satisfies the stormwater discharge provisions of the Federal Clean Water Act, as amended, (33 U.S.C. § 1251 et seq.), 40 CFR 122, 123, and 124, as amended, et. seq.; Minn. Stat. chs. 115 and 116, as amended, and Minn. R. chs. 7001 and 7090. In Minnesota, NPDES rules are developed and administered by the MPCA. The SWPPP identifies potential pollutant sources at the facility and describes controls for BMPs that are and would continue to be used at the facility to minimize pollutants in runoff. The proposed project would not change the quantity of runoff. In accordance with the facility’s NPDES/SDS General Industrial Stormwater Permit and SWPPP, on-site stormwater is collected and contained on site by catch basins and routed trenches and piping to the stormwater pond, where it is discharged as needed to the adjacent wetland area.

b. Identify routes and receiving water bodies for runoff from the site; include major downstream

water bodies as well as the immediate receiving waters. Estimate impact runoff on the quality of receiving waters. Several wetlands were identified within one mile of the project site. The west side of the project site is undeveloped and occupied by wetlands. Two stormwater structures discharge to the wetlands. The first structure is an overflow outlet that is connected between the stormwater pond and the wetlands. Since the stormwater pond was constructed, stormwater has not been discharged through the overflow structure. The second stormwater outlet is located southwest of the transfer station building

Page 10: Randy's Sanitation Transfer FAcility Proposed … Title: Randy’s Sanitation Transfer Facility Proposed Capacity Expansion 2. Proposer: Randy’s Sanitation, Inc. 3. RGU: Minnesota

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 9 Worksheet

within the wetland. This outlet is connected to one catch basin and two exterior trench drains (Figure 3). However, the wetlands would not be impacted by the proposed project, as total quantity and quality of stormwater runoff would not change. As part of the existing NPDES/SDS Industrial Stormwater Permit, an SWPPP was prepared that identified one impaired water body, Crow River (South Fork) that was within a one mile radius of the facility. The Crow River is impaired with respect to chloride, fecal coliform bacteria, turbidity, mercury, and the Biological Integrity of fish communities. The mercury Total Maximum Daily Load (TMDL) plan that applies to this reach of the Crow River is the state-wide plan for mercury. Based on the review of topographic maps and visual site observations, stormwater runoff from the site does not appear to directly discharge to the Crow River.

18. Water Quality – Wastewater. a. Describe sources, composition and quantities of all sanitary, municipal and industrial wastewater

produced or treated at the site. Existing facility operations for the transfer building generate a small quantity of leachate from waste handling and occasional tipping floor washing. The transfer building has two 350 gallon tanks and one 265-gallon tank that are located beneath the tipping floor and recycling areas. These tanks are used to collect solids and liquids during operations. The quantity of the solids and liquids in the tanks varies depending on the waste and its moisture content. On average, these tanks are pumped twice per year or when one of them fills. Since this liquid has been in contact with waste, it is considered contaminated and classified as leachate; therefore, treatment is required. A third-party contractor is used to pump the tanks. The leachate is tested every three years to ensure compliance with disposal requirements. The solids from Randy’s tanks are disposed of at the Veolia ES Rolling Hills Landfill near Buffalo, Minnesota, while the liquid (leachate) is hauled to the MCES Metro WWTF in St. Paul, Minnesota for disposal. Leachate present during waste processing that is not collected by the tanks below the tipping floor and recycling areas is discharged via the city sanitary sewer to the city of Delano Wastewater Treatment Facility (Delano’s WWTF). The quantity of leachate produced at the facility is dependent upon the waste type and moisture content. Rainy, wet weather typically causes the waste to have a higher moisture content, which results in more leachate at the facility. The proposed project would increase MSW tonnage, but is not anticipated to significantly increase leachate quantity and, therefore, the current method of leachate management would continue to be used after completion of the project. Additionally, Randy’s has launched a source-separated composting program, the Blue Bag Organics Program, that will further help reduce the moisture content of the waste by removing organics, such as food waste, that tend to have a naturally higher water content. Additional discussion about the Blue Bag Organics Program is provided in Item 20. Randy’s also produces a small quantity of domestic wastewater from their office and maintenance buildings that are located on site. This wastewater is also discharged to the Delano WWTF. A small quantity of leachate is also collected in tanks in the maintenance building that are pumped about two times per year or as needed when they fill, and the leachate hauled to a wastewater treatment facility. The proposed project would not change the current operation of the office and maintenance facility and, therefore, no change in domestic wastewater is anticipated.

b. Describe waste treatment methods or pollution prevention efforts and give estimates of composition after treatment. Identify receiving waters, including major downstream water bodies (identifying any impaired waters), and estimate the discharge impact on the quality of receiving waters. If the project involves on-site sewage systems, discuss the suitability of site conditions for such systems.

The quantity and quality of the leachate at the existing facility has not required pretreatment of the leachate prior to discharge to Delano’s WWTF. The Delano WWTF is permitted to discharge to the Crow River, which eventually discharges to the Mississippi River. The NPDES/SDS Permit for the Delano WWTF includes specific effluent limits and monitoring requirements prior to discharge. Additionally, Randy’s has an SWPPP in place that outlines the emergency response measures to be taken in case of a spill and potential for contamination of surface waters at the facility.

c. If wastes will be discharged into a publicly owned treatment facility, identify the facility, describe any pretreatment provisions and discuss the facility’s ability to handle the volume and composition of wastes, identifying any improvements necessary. Wastewater from Randy’s is discharged to the Delano WWTF. The Delano WWTF is permitted to discharge to the Crow River, which eventually discharges to the Mississippi River. The NPDES/SDS Permit for the Delano WWTF includes specific effluent limits and monitoring requirements prior to discharge. The Proposer is required to obtain or update prior approval, through permits or agreements with the city of Delano, for the discharge to the Delano WWTF.

19. Geologic hazards and soil conditions. a. Approximate depth (in feet) to Ground water: 27 minimum; average. Bedrock: 151 minimum; average. Describe any of the following geologic site hazards to ground water and also identify them on the

site map: sinkholes, shallow limestone formations or karst conditions. Describe measures to avoid or minimize environmental problems due to any of these hazards. The facility is not located in an area that has sinkholes, shallow limestone formations, or karst conditions, nor is any construction taking place; therefore, the proposed project would not pose a hazard to groundwater.

b. Describe the soils on the site, giving Natural Resources Conservation Service classifications, if known. Discuss soil texture and potential for ground-water contamination from wastes or chemicals spread or spilled onto the soils. Discuss any mitigation measures to prevent such contamination. There are three main soil classifications on the 21-acre facility property: Angus, Cordova, and Houghton. The wetland to the west of the project site consists of Houghton soils that are considered hydric. The project area consists of Angus soils that are typically fine-loamy, mixed, mesic Mollic Hapludalfs. Slightly south of the proposed project on the existing footprint are Cordova soils that are also considered hydric. However, some soils on the project site have been altered to suit construction of structures, as summarized in the text that follows.

In 1994, Braun Intertec Corporation conducted a geotechnical evaluation within the general location of the proposed project. The evaluation encountered fill soils overlying stiff to hard glacial till. For the purposes of supporting the transfer station building (i.e., the proposed project at that time), Braun recommended removing the soft fill soils and replacing them controlled, compacted backfill, which is what the project proposer did in the summer and fall of 1994. Upon completion, the excavation ranged in depth from approximately 16 to 27 feet below existing grades. Engineered fill soil was placed in 6 to 12 inch lifts and compacted to a minimum of 95 percent of standard Proctor density (ASTM D 698). Groundwater was not observed in the excavation bottoms during the soil work. The potential for groundwater contamination at the facility is low given the hydrogeology of the area. Past excavation work at the site has also indicated that groundwater depth is greater than 27 feet. Additionally, the facility operates under an NPDES/SDS Permit that regulates its industrial stormwater discharge. Changes in discharge are not anticipated as discussed in Item 17 and appropriate measures are in place to prevent and contain spills from operations at the facility. Additionally, the site is covered by impervious surface and includes a stormwater management system, which would prevent any spills from coming into direct contact with soils.

20. Solid Wastes, Hazardous Wastes, Storage Tanks. a. Describe types, amounts and compositions of solid or hazardous wastes, including solid animal

manure, sludge and ash, produced during construction and operation. Identify method and location of disposal. For projects generating municipal solid waste, indicate if there is a source separation plan; describe how the project will be modified for recycling. If hazardous waste is generated, indicate if there is a hazardous waste minimization plan and routine hazardous waste reduction assessments. The proposed project is to increase permitted operating capacity at an existing MSW transfer station and recycling facility. Operations conducted at the facility include municipal and industrial solid waste collection for transfer to a landfill, appliance recycling (receiving, sorting, and shipping), vehicle and equipment maintenance, vehicle washing, vehicle, trailer, and container storage, and vehicle and equipment fueling. Solid waste is delivered to the transfer station, weighed, processed, and shipped off site via semi-trailers primarily to landfills authorized to accept the waste, such as the Elk River Landfill in Sherburne County, or Spruce Ridge Landfill in Glencoe, Minnesota. Recyclables are collected and stored, then transferred or sold to various markets as market conditions allow. The current MPCA permit for the facility allows for the transfer of a combined maximum of 78,250 tpy (up to 350 tpd) of MSW, source separated organic materials, approved industrial waste, construction and demolition debris, white goods, electronics, and tires. The permit also authorizes the project proposer to accept and transfer up to 5,500 tpy of yard waste. Randy’s is also authorized to process and transfer up to 2,010 cy of recyclables at the site at any one time. The proposed capacity expansion would allow Randy’s to process and store up to 3,500 cy of recyclables. The recyclables capacity does not include source separated organics and recyclables stored in enclosed containers and enclosed trailers on site. It only applies to those recyclables stored within the recycling portion of the transfer building. Randy’s also provides an additional compost option for residential customers on a subscription basis through its Blue Bag Organics program. This allows customers to source separate their food waste for recycling/composting. If enrolled in the program, Randy’s offers a “buy down” discount of one

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 12 Worksheet

container rate (using a 32-gallon service as the base) as an incentive to enroll in the program. Blue Bags, which are compostable, are picked up by the waste haulers and delivered to Randy’s facility. Randy’s separates the bags, which are then processed for use as compost for gardens, lawns, and other small-scale agricultural uses. The proposed project would increase the MSW processing capacity of the existing facility from 78,250 tpy to 125,000 tpy (up to 550 tpd). Randy’s will continue to facilitate source-separated recycling with its customers that deliver to its MRF for single-stream recyclables processing. The Blue Bags Organics program would also continue to be promoted by Randy’s as an additional way to reduce waste and create compost for potential reuse. Randy’s stated goal for the proposed project is to have 65 percent of the waste entering the facility be recycled, while only 35 percent would require disposal at a landfill. Further detail on the proposed project is provided in Item 6. Randy’s solid waste management permit would be modified to reflect the proposed project.

b. Identify any toxic or hazardous materials to be used or present at the site and identify measures to be used to prevent them from contaminating ground water. If the use of toxic or hazardous materials will lead to a regulated waste, discharge or emission, discuss any alternatives considered to minimize or eliminate the waste, discharge or emission.

Hazardous constituents used in the maintenance of the facility vehicles and dumpsters including batteries, used oil, new motor oil, hydraulic oil, washer fluid, brake fluid, transmission fluids, paints, and antifreeze are stored on site until they are used in the facility vehicles or recycled. Appliances, electronics, tires, and batteries to be recycled are received at the project site and are loaded directly into box trailers until they are shipped off site for processing. No processing or removal of hazardous components is performed on site. Loads of MSW are inspected as they are dumped on the tipping floor. The facility operator can view the waste from the control booth as it is being unloaded. Staff working on the tipping floor also inspects the waste. Household hazardous waste (HHW) or other unacceptable waste that arrives within the loads of MSW is identified and segregated from the waste stream prior to entering the processing system. HHW is temporarily stored in 20-gallon or other appropriately sized plastic storage bins that are marked has HHW. The HHW is separated by type and stored accordingly to meet MPCA HHW storage requirements. HHW materials are periodically removed from the site and disposed of by a licensed contractor. Additionally, the facility operates under an NPDES/SDS Industrial Stormwater Permit, which requires an SWPPP for industrial stormwater discharge, as further described in Item 17. The SWPPP outlines requirements for meeting stormwater standards, including measures to be taken if hazardous waste potentially comes into contact with stormwater. The SWPPP would be modified as needed to reflect the proposed project.

c. Indicate the number, location, size and use of any above or below ground tanks to store

petroleum products or other materials, except water. Describe any emergency response containment plans. Two fuel pumps and a 10,000-gallon diesel underground storage tank are located southeast of the scale. There are two above ground storage tanks used to store used oil. The tanks are 400 gallons each, and emptied via pumping, with the material disposed of once they reach capacity. There is also

Page 14: Randy's Sanitation Transfer FAcility Proposed … Title: Randy’s Sanitation Transfer Facility Proposed Capacity Expansion 2. Proposer: Randy’s Sanitation, Inc. 3. RGU: Minnesota

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 13 Worksheet

an 85-gallon tank for compressed natural gas (CNG), used to refuel the CNG fleet of vehicles. An SWPPP has been developed for the facility and outlines measures that will be used in case of emergency to contain spills.

21. Traffic.

Parking spaces added: NA Existing spaces (if project involves expansion): approximately 170 (employee and haul truck spaces Estimated total average daily traffic generated: 225 to 250 vehicles per day Estimated maximum peak hour traffic generated and time of occurrence: Traffic varies, but operation of

the facility is Monday through Friday. Haul trucks typically leave the facility between 4 a.m. and 7 a.m., complete their route, then return to the facility between 1 p.m. and 4 p.m.

Indicate source of trip generation rates used in the estimates: The Proposer’s data and records

If the peak hour traffic generated exceeds 250 vehicles or the total daily trips exceeds 2,500, a traffic impact study must be prepared as part of the EAW. Using the format and procedures described in the Minnesota Department of Transportation’s Traffic Impact Study Guidance (available at http://www.oim.dot.state.mn.us/access/pdfs/Chapter%205.pdf) or a similar local guidance, provide an estimate of the impact on traffic congestion on affected roads and describe any traffic improvements necessary. The analysis must discuss the project’s impact on the regional transportation system. The facility uses a number and variety of trucks, including packer trucks, recycling trucks, roll-off trucks, and assorted support vehicles, which total approximately 35 vehicles. The majority of the waste entering the facility is hauled by Randy’s fleet of trucks that return to the site at the end of the day. Randy’s facility in Delano operates from 4:00 a.m. to 2:00 a.m. Mondays through Saturdays. Facility maintenance typically takes place from 2:00 a.m. to 4:00 a.m. There are also other haulers that bring material to the facility, which consist of approximately 20 visits per day, including MSW and recycling vehicles. A daily total of approximately 10 to 12 semi-trailers haul from the facility. The existing traffic flow in and out of the facility is summarized in Table 1.

Table 1: Existing Traffic Flow

Vehicle Type Number of Vehicles per Day Collection Vehicles 55 Tractor/Trailer 12 Support Vehicles 3 Visitors/Vendors 24 Employees 92 TOTAL Vehicles per Day 186

Collection vehicles proceed to the transfer station or recycling facility on site to deliver their load. After delivery, these trucks may leave the facility to continue their pickup route. However, most deliveries from collection vehicles are at the end of the truck’s particular collection route. In that case, the truck is parked and/or serviced at the on-site truck maintenance facility. Trucks from other commercial haulers are weighed before tipping at the facility. Before leaving, those trucks return to the scale to be weighed, and then exit the facility.

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 14 Worksheet

Access to the facility is from US Highway 12 just north of downtown Delano. The Annual Average Daily Traffic (AADT) during 2010 for this stretch of highway was 11,500 vehicles. The Heavy Commercial AADT was 710 vehicles. The section of highway in front of the facility was upgraded approximately 10 years ago to include left and right turn lanes into the facility, which aids traffic flow into the facility and for through traffic. There is also a signal controlled intersection on US Highway 12 and Bridge Street (downtown Delano), which staggers traffic at peak hours of the day.

The facility consists of impervious surface sufficient to handle large trucks and their associated loads. The site has also been designed to accommodate efficient traffic flow within and through the facility.

Traffic associated with the proposed expansion would remain similar to existing levels with a small increase in collection vehicles and employee vehicles. The proposed expansion would allow the facility to accept larger quantities of MSW for processing. This would include larger truck loads, approximately eight tons per vehicle, and some additional collection vehicles from third party haulers. Table 2 summarizes the anticipated number of vehicles necessary to accommodate the proposed expansion.

Table 2: Estimated Traffic Flow for the Proposed Expansion Vehicle Type Number of Vehicles per Day Collection Vehicles 68 Tractor/Trailer 15 Support Vehicles 3 Visitors/Vendors 24 Employees 118 TOTAL Vehicles per Day 228

The project would result in an increase in traffic into and exiting the facility at certain times of the day. The impact to traffic flow on US Highway 12 is not anticipated to be significant as appropriate infrastructure and traffic lanes are currently in place to accommodate anticipated traffic levels.

22. Vehicle-related Air Emissions. Estimate the effect of the project’s traffic generation on air quality, including carbon monoxide levels. Discuss the effect of traffic improvements or other mitigation measures on air quality impacts.

The existing facility generates vehicle-related air emissions resulting from vehicles and haul trucks driving to and from the facility. Randy’s maintains its fleet of vehicles to ensure proper and efficient operation. This helps keep the vehicle operating within vehicle emission standards. Additionally, Randy’s has begun replacing their diesel-fueled trucks for new haul trucks that run on CNG. This is a cleaner burning fuel with vehicle-related air emissions that have potentially less impact on air quality. Based on traffic information for the proposed project, traffic would not change significantly from existing levels and, therefore, vehicle-related air emissions would not significantly increase or change existing air quality.

23. Stationary Source Air Emissions. Describe the type, sources, quantities and compositions of any emissions from stationary sources of air emissions such as boilers, exhaust stacks or fugitive dust sources. Include any hazardous air pollutants (consult EAW Guidelines for a listing), any greenhouse gases (such as carbon dioxide, methane, and nitrous oxides), and ozone-depleting chemicals (chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons or sulfur hexafluoride). Also describe any proposed pollution prevention techniques and proposed air pollution control devices. Describe the impacts on air quality.

There are currently no stationary sources of air emissions associated with existing operations at this facility, and no new stationary sources proposed as a result of the project.

24. Odors, noise and dust. Will the project generate odors, noise or dust during construction or during operation? Yes No

If yes, describe sources, characteristics, duration, quantities or intensity and any proposed measures to mitigate adverse impacts. Also identify locations of nearby sensitive receptors and estimate impacts on them. Discuss potential impacts on human health or quality of life. (Note: fugitive dust generated by operations may be discussed at item 23 instead of here.)

Odors The operations of the facility occur within an enclosed building; therefore, significant odor is not anticipated beyond the immediate confines of the facility. There have not been any odor complaints received during past operations, and the proposed expansion would operate in the same manner as existing operations. Litter Site activities occur primarily within enclosed buildings. Storage of materials typically occurs inside the buildings. Any product stored outside the facility is inside a container, trailer or otherwise covered in order to minimize windblown litter. Litter that may become separated from the waste processing stream is collected on a regular basis by Randy’s employees on site. Litter has not been and is not anticipated to be an issue with the proposed expansion. Dust The facility site is covered by an asphalt surface that produces little dust. The transfer and recycling buildings have ventilation systems that minimize dust and fumes in the working area. The proposer is must comply with permit SW-578 provisions requiring the facility to prevent particular matter from becoming airborne. Noise Operations for the processing of waste at the facility are enclosed within buildings and, therefore, create low noise levels outside of the buildings. Noise from delivery and shipment traffic and heavy machinery (waste delivery, operations, cleaning, or snow removal) is minimal, and may consist of engine noise and short durations of back-up safety beepers on trucks and machinery. The facility is located within a commercial and industrial area and has undeveloped land on the west and north sides that create buffer areas to other properties. There have been no complaints regarding noise at the facility. The proposed expansion would operate the same as the existing facility.

25. Nearby resources. Are any of the following resources on or in proximity to the site? a. Archaeological, historical, or architectural resources? Yes No b. Prime or unique farmlands or land within an agricultural preserve? Yes No c. Designated parks, recreation areas, or trails? Yes No d. Scenic views and vistas? Yes No e. Other unique resources? Yes No

The State Historic Preservation Office (SHPO) Minnesota Archaeological Inventory and Historic Structures Inventory was queried to determine if any cultural resources existed that may be impacted by the proposed expansion. The result of this database search typically provides a listing of recorded archaeological sites and historic architectural properties that are included in the current SHPO databases. The results of the

Page 17: Randy's Sanitation Transfer FAcility Proposed … Title: Randy’s Sanitation Transfer Facility Proposed Capacity Expansion 2. Proposer: Randy’s Sanitation, Inc. 3. RGU: Minnesota

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 16 Worksheet

database query for the proposed expansion did not identify any archaeological sites or historic structures on or within the vicinity of the project site. There are no parks, recreation areas, or other scenic or unique resources located near the project site.

26. Visual impacts. Will the project create adverse visual impacts during construction or operation? Such as

glare from intense lights, lights visible in wilderness areas and large visible plumes from cooling towers or exhaust stacks? Yes No The facility is visible from US Highway 12, but operations typically occur within the transfer and recycling building. Aspects of the facility operation that are visible from US Highway 12 include any lights necessary for safe operations. A fence, parking area, and a large grassy parcel separate the transfer and recycling building from US Highway 12. The southeast and south sides of the facility are screened from view of US Highway 12 by large evergreen, spruce trees. Other adjacent properties are currently undeveloped. In addition, no new structures are to be built; therefore, it is expected that there will be no significant visual impacts from the proposed project.

27. Compatibility with plans and land use regulations. Is the project subject to an adopted local comprehensive plan, land use plan or regulation, or other applicable land use, water, or resource management plan of a local, regional, state or federal agency? Yes No

Local Plans and Land Use Regulations The proposed project would allow the existing facility to process additional MSW and recyclables, which is compatible with existing land uses, plans, and regulations on and adjacent to the project site. State Plans and Regulations As required by Minnesota state rules, the facility operates under an MPCA-approved solid waste disposal permit (SW-578 Permit). In addition to state rules regulating solid waste, Minn. Stat. § 115A.02b describes the Minnesota Waste Management Hierarchy, which was developed to foster an integrated waste management system for the state. The hierarchy outlines waste management practices in order of preference: 1) Waste reduction and reuse; (2) Waste recycling; (3) Composting of yard waste and food waste; (4) Resource recovery through mixed municipal solid waste composting or incineration; (5) Land disposal which produces no measurable methane gas or which involves the retrieval of methane gas as a fuel for the production of energy to be used on-site or for sale; and (6) Land disposal which produces measurable methane and which does not involve the retrieval of methane gas as a fuel for the production of energy to be used on-site or for sale. The facility is a transfer station and recycling facility, which primarily functions at number 5 on the hierarchy, with MSW being transferred to permitted landfills off site. The proposed project would allow the facility to increase its MSW processing capacity from 78,250 to 125,000 tpy, and allow for more recycling of waste. The SW-578 Permit for the facility will need to be modified to incorporate the proposed project. The Proposer is required to meet all applicable requirements of the SW-578 Permit.

Randy’s Sanitation Transfer Facility Proposed Capacity Expansion Environmental Assessment City of Delano, Franklin Township, Wright County 17 Worksheet

28. Impact on infrastructure and public services. Will new or expanded utilities, roads, other infrastructure or public services be required to serve the project? Yes No The proposed project would not require new or expanded utilities, roads or other public infrastructure. Access to the facility is from US Highway 12. The section of highway in front of the facility was upgraded approximately 10 years ago to include left and right turn lanes into the facility, and would not require additional upgrades for the proposed expansion.

29. Cumulative potential effects. Minn. R. 4410.1700, subp. 7, item B requires that the RGU consider the

“cumulative potential effects of related or anticipated future projects” when determining the need for an environmental impact statement. Identify any past, present or reasonably foreseeable future projects that may interact with the project described in this EAW in such a way as to cause cumulative potential effects. (Such future projects would be those that are actually planned or for which a basis of expectation has been laid.) Describe the nature of the cumulative potential effects and summarize any other available information relevant to determining whether there is potential for significant environmental effects due to these cumulative effects (or discuss each cumulative effect under appropriate item(s) elsewhere on this form).

No significant cumulative environmental effects have been identified for the project. See also Item 17 and Item 21 for information related to impaired waters and truck traffic, respectively.

30. Other Potential Environmental Impacts. If the project may cause any adverse environmental impacts

not addressed by items 1 to 28, identify and discuss them here, along with any proposed mitigation. Randy’s had previously constructed the additional tipping floor space. The work was reviewed for compliance with both solid waste and construction stormwater requirements, and determined adequate. The MPCA did issue a Notice of Violation to Randy’s for proceeding without prior permit approval for the activity.

31. Summary of issues. List any impacts and issues identified above that may require further investigation before the project is begun. Discuss any alternatives or mitigative measures that have been or may be considered for these impacts and issues, including those that have been or may be ordered as permit conditions. The existing facility can accommodate the proposed project and, therefore, no structural changes would be necessary. There will be an increase in traffic resulting from the proposed project, but this increase is not anticipated to impact local and regional roadways. Necessary turn lanes and infrastructure for US Highway 12 are already in place to accommodate traffic in the area of the facility.
