Definition: Road mile distance measured from proposed site to waste generation centroid - 2025 Mean Center (weighted by population and employment). 9 $ 1 1 2. ACCESS TO MAJOR TRANSPORTATION ROUTES Very Important 10 Consideration: The transfer station should have direct and convenient access to truck routes, major arterials, and Site with most direct or convenient access to highways. Access to rail would also afford additional transfer and disposal flexibility in the future. truck routes, major arterials, and highways It is preferable to avoid routing collection and transfer vehicle Uaffic through residenflal subdivision will be ranked highest. Street or roadway areas because traffic generated by transfer stations contributes to congestion; increased risk to connectors must accommodate through pedestrians; increased air emissions, noise, and wear on roads; and might contribute to litter traffic with the following functional problems, requirements: Parking-restricted (no parking on road); Major Intersections - Definition: Direct or convenient access to truck routes, major arterials, highways, andlar potential rail or traffic signals & cross street stops; Posted intermodel access. Major truck routes, arterials, and highways will be defined as 15-501, NC 54; Speed Limit- 35.45 MPH; and Truck Traffic NC 86 (excluding NC 86 north of Hillsborough), US 70, I-40, or I.85. -unrestricted. Potental rail access will be used to futther differentiate site rankings (e.g., sites with a lower truck access ranking that have rail access will be reevaluated in terms of final technical ranking.

PARCEL SIZE AND AVAILABILITY Very Important 10 Consideration, The area required for specific transfer stations varies significantly, depending on the volume of Single parcel, freely offered, sites will be waste to be transferred, rates at which waste will be delivered, the functions to be carried out at the ranketl'highest, site, and the types of customers the facility is intended fo serve. Locating a site of sufficient size is critical to operating efficiencies and minimizing impacts on the surrounding community, Definition: The minimum site size to be initially considered will be 25 acres as established under the Exclusionary Criteria. Co-location sites with other municipal facilities or operations of less than 25 acres will be considered provided that transportation. access, buffers, and preliminary transfer e mlcclrlcAl station layout and roadway configurations demonstrate, the adequacy of a smaller site, T conrc eno nAl CITC onnnurnve nI IcnlAlr nAln onaulnlr ~ 1 ' ers: f 4. SUFFICIENT SPACE FOR ON~SITE ROADWAYS, QUEUING, AND PARKING Important 5 Consideration, Transfer stations typically have on-site roadways to move vehicles around various parts of the The site that lends itself to the most efficient transfer Site. Waste collection, Uucks can be up to 40 feet Ieng. Transfer trailers that move waste design in terms of roadway geometry and to a disposal facility are typically 5D to 70 feet long. These vehicles need wide roadways with layout will be ranked highest; Roadway , gradual slopes and curves to maneuver efficiently and safely. Also, the site will need space for widths, maximum slopes, number of laces, parking transfer vehicles and to allow incoming and outgoing traffic to form lines without backing up turning radius, and traffic flow pattern will be onto public roads. considered. Definition: On-site roadways and maneuvering areas will meet the fallowing minimum requirements: down slope vehicle ramps must be less than 10%; upward sloped ramps must be less than 6%; roadway widths for collection vehicle and Transfer vehicle traffic must be 24 feet; inbound and outbound collection vehicle queuing (in front of scale) must accommodate 4 vehicles with provisions fora tloublestack using bypass or outbound lanes (i.e., stage 8 inbound collection vehicles); queuing for 4 transfer vehicles including trailers positioned under load-out hoppers; staff parking fot 5 vehicles . plus 2 visitors; and trailer storage for 4 to$ units.

Transfer stations often receive urges of traffic when collection vehicles have. finished theicroutes. Transfer stators traffic varies locally but tends to peak twice a day. The first peak is often near the middle of the day or shift, end the second at the end of the day or shift,.. Therefore, the best sites for transfer stations are located away from areas hat have midday. traffic peaks antlfor school bus and pedestrian traffic, Definition: Cornpafibility of projected transferstation traffic volume and'vehicle types with existing traffic mix and flow patterns in the immediate area of the site, R ARII ITV Cf1D CYDAhIQIf1Al 6. ABILITY FOR EXPANSION Consideration, When selecting a site, consider the potential for subsequent increase, in the daily tonnage of waste that the facility will be required to manage, or added processing capabilities for recycling and diversion. It is often less expensive to expand an existing transfer station than to develop a new site due to the:ability to use existing operations staff, ublity connection, traffic control systems, office space; aril tiuiltlings, Def nifion: Adaptability of proposed transfer station site layout (transfer building and on-site roadways) to accommodate future expansion or changes in waste transfer and processing. Sites with street or roadway,connector access that do riot currently,or are not projected in the future to eztiibit significant midday traffic peaks and school bus or pedestrian traffic shall be ranked highest. land use and development within one half mile radius of proposed site will be used to assess potential compatibility issues related to connector streets and roads. A site that is the most adaptable with respect to expansion of the transfer building with concurrent use of buffers, roadways, parking areas, scale facilities, and other required site improvements will be ranked the highesk Page 3 Fn .4 } ~ a~~ Very Important Important 10 5 Attachment 1A BOCC Work Session - 06!16!08 i i t 7, SPAGE FOR RECYCLING, COMPOSTING, AND PUBLIC EDUCATION Consideration: A transfer station could be sited in areas also conducive to recycling or composting activities. Many transfer stations are designed to enable residents and businesses to drop of(recyclables and yard waste in addition to trash: Some Transfer stations incorporate education centers or interpretive trails focusing on waste prevention, These types of facilities offer increased utility to the community, Definition: . Availability of undeveloped on-site area to accommodate future expansion or changes including additional waste handling, transfer, processing, and/or administrative support functions. t 'I I i~ness; ets~: ¢-M+mme+~5it-feet: 8. BUFFER SPACE Consideration: To mitigate the impact onthe surrounding community, a transfer station should be located in an area that provides separation from sensitive adjoining land uses and/or residences. Buffers can be natural or constructed and can take many forms, including open spaces, fences, sound walls, trees, berms, and landscaping. Definition:. Presence of natural areas, trees, topographic relief, or other features that provide separation from adjoining land use or residences. A site with the largest available undeveloped footprint (acres) not including a minimum 100-foot buffer around the perimeter of the site and dedicated transfer station area , (station, roadways, parking areas, scale facilities, and other required site improvements for transfer operations) will be ranked the highest. A site that provides the most buffer width in terms of wooded area or other natural screening feature(s) (i.e., streams, hills, etc.) around the perimeter of the property will be ranked the highest,.

ACCESS TO UTILITIES Consideration Transfer stations generally require electricity to operate equipment, such as ventilation fans; lighting; water for facility cleaning, restrooms, and drinking; and sanitary sewer systems for wastewater disposal. Some transfer. stations use,wells for water supply, and some, especially in more. rural settings, use. septic systems or truck their wastewater for off site treatment,, Definition: Availability of electrical, water, and sewer service at the site, A site that has a moderate naturally sloping topography it the range of 4% to 6% (from the back of transfer building) will be ranked the highest, A site that has electrical, water aril sewer service of sufficient capacity for transfer operations within the immediate vicinity (10D0 feet of the site) will be ranked the. highest; Page 5 Important 5 Important 5 Attachment 1A BOCC Work Session - 06/16/08 Attachment 1A t~; ~ ~ ~ ~ ~~ ~~~ ~; r 3 ~ a ~. y I imi{ cifinn nnFinnc t 11. ZONING DESIGNATIONS AND REQUIREMENTS Consideration The County has adopted a Zoning Ordinance in order to protect and promote the health, safety, and general welfare of the County and its residents. The Zoning Ordinance regulates and restricts uses of land within the County, including such things as the height, size of buildings, and other structures; the percentage of a lot that may be occupied; the size of yards, courts, and other open spaces; the density of populations; and the location of Governmental Facilities such as aCounty- ownetlTransfer Station. If the selected transfer station site is not located within an area that is within the County's exclusive planning jurisdiction then other units of government may be involved in the permitting and approval of the proposed transfer station site. Definition: A Trarisfer station can be located in all Zoning Districts in the exclusive planning jurisdiction of the County where Governmental Facilities and Office Buildings are permitted pursuant to Article 4.3 Permitted Use Table (Line P24) of the County's Zoning Ordinance, including those areas of the Rural Buffer not located in protected watershed critical areas and including anywhere in any of the EDDs where Governmental Facilities and Office Buildings are permitted pursuant fo the Permitted Use Tables contained within the EDD Manuals, subject to all Site Plan requirements contained within Article 14 of the Zoning Ordinance, EDD Manual requirements, permits and approval .processes as applicable. t ''-o,e~ mau?e-gas-em+ss~e~ s -Aufernebiie--l-psuntl-SOi~le~~rEVen 12. CARBON FOOTPRINT Consideration Refuse trucks provide an invaluable service, improving the quality of life as they haul away thou- sands ofpounds ofgarbage every day, However, the refuse trucks also contribute to air and noise pollution. Nearly 99 percent of these vehicles run on diesel fuel, and the emissions from these diesel engines contain particulate matter, hydrocarbons, carbon monoxide, and nitrogen oxides, Definition Impact of waste hauling activities on the environment measured in terms of the greenhouse gas (measured in units of carbon dioxide) emissions. Important Sites will be ranked in accordance with the following hierarchy: A site that is located within the Orange County Planning jurisdiction, excluding the Rural Buffer portion of the Joint Planning Area and excluding the Transition area, will be ranked the highest followed respectively by sites located. in the Rural Buffer, Transition, ETJ, with those sites located within a municipality ranked the lowest. Important The site with the lowest environmental impact will be ranked the highest. Environmental impact will be assessed on the basis of carbon dioxide emissions (megagrams per year) from collection vehicles for the increased travel distance from the cenfroid of waste generation to the proposed transfer station site, Page 6 Attachment 1A BOCC Work Session - 06/16/08
