Central Accumulation Area

The Central Accumulation area is the storage area where containers of hazardous waste that have been stored in a SAA or are otherwise generated anywhere on campus are stored for a temporary period. By the end of that period, the hazardous waste is packaged and transported by a licensed waste handler to a transfer storage disposal facility (TSDF).

The temporary storage period is dependent on generator status. Both AU non-statutory and NYSCC statutory colleges are Small Quantity Generators (SQG).

A Small Quantity Generator:

  1. Generates greater than 100 kilograms (220 lbs.) but less than 1000 kilograms (2200 lbs.) of hazardous waste in a calendar month.
  2. May accumulate hazardous waste in a Central Accumulation Area for 180 days or less without a permit or without having interim status provided that the quantity of waste on-site never exceeds 6000 kilograms (13,200 lbs.) of hazardous waste or 1 kilogram (2.2 lbs.) of acutely hazardous “P” listed waste.

Alfred University has three 180 day Central Accumulation Areas:

  1. Harder Hall, room 136B accepts hazardous waste from NYSCC Art & Design contact EH&S @2190.
  2. McMahon, room 237 accepts hazardous waste from all other areas of NYSCC contact @2497 or EH&S @2190.
  3. Myers Hall, room 110 accepts hazardous waste from all areas of AU non-statutory contact EH&S @2190.

Central Accumulation Areas must adhere to the following requirements:

  1. Storage areas, in general, must be:
    1. Located at least 50 feet from the property line.
    2. Secure against unauthorized entry.
    3. Placed on a surface which does not show any cracks or gaps and is impervious to the hazardous waste being stored.
    4. Constructed with secondary containment if CAA is an outside storage building - This secondary containment may consist of a berm or a dike with an impervious surface (i.e., plastic liner), but must be large enough to hold:
      1. 10% of the total volume of all containers, or
      2. 110% of the volume of the largest container, whichever is larger.
    5. Clearly marked by a fence, a visible line, or other visible barrier, and be separate from any points of generation.

Central Accumulation Areas must adhere to the following requirements:

  1. Storage areas, in general, must be:
    1. Separated from virgin materials.
    2. Maintained and cleaned properly of any spill residues.
    3. Kept neat and orderly and arranged with adequate aisle space to allow access for emergency personnel and equipment.
    4. Equipped with:
      1. Communication device such as a phone or walkie-talkie.
      2. Spill response materials.
      3. ABC fire extinguisher.
      4. Eyewash and shower which are tested weekly.
      5. Water at an adequate volume and pressure to supply water hose streams, or automatic sprinklers.
    5. Clearly posted with :
      1. CAA “Hazardous Waste” signage provided by EH&S.
      2. Incompatible Waste chart.
      3. “No Smoking” sign.
      4. Emergency information next to the phone or walkie-talkie in the area.
        1. AU/NYSCC Emergency phone numbers
        2. name and phone # of Emergency Coordinator
        3. location of spill control material
        4. location of fire alarms
        5. location of fire extinguishers
        6. phone # of fire department
  2. Container labeling:
    1. Waste containers are labeled with the yellow AU waste label stating the:
      1. Words “Hazardous Waste”.
      2. Start date, full date, the date the waste enters the CAA.
      3. Names of chemicals in the container (not a chemical formula) including volume/concentration.
      4. Appropriate waste characteristics box(s) marked by test or knowledge.
    2. For wastes undergoing hazardous waste determination testing,
      1. Manage these wastes as hazardous (labeling, storage, etc.) until test results are received.
      2. The accumulation start date is when the waste was first generated not when the test results are known.
  3. Containers:
    1. Must always be closed during storage, except when it is necessary to add or remove waste.
    2. Holding hazardous waste must not be opened, handled, or stored in a manner which may rupture the container or cause it to leak.
    3. Must be in good condition; if it begins to leak, bulge, rust, or is otherwise damaged, place the degraded container into a larger secure container or, if this is not possible, carefully transfer the hazardous waste to a container that is in good condition.
    4. Must be compatible with the waste being stored. Waste must not be placed in the same container or in an unwashed container that previously held an incompatible waste or material.
  4. Container storage:
    1. Shelves used to hold waste containers must be in good condition.
    2. Flammable storage cabinets must be used when storing greater than 25 gallons of flammable waste.
    3. Incompatible wastes must be segregated to the greatest extent using secondary containment, berms or distance. (see Incompatibility Chart)
    4. Store potential explosives securely and separately. (peroxides, perchlorates, picrics, etc.)
    5. Must be stored for specified time limit:
      1. SQG – 180 days.
      2. LQG – 90 days.
  5. Inspections:
    1. Central Accumulation Areas must be inspected weekly.
    2. Inspection criteria are listed on Hazardous Waste Central Accumulation Area Inspection form provided by EH&S.
    3. Inspection form must be completely filled out, signed, dated and submitted to EH&S, 117 Myers Hall.
  6. Hazardous Waste Log:
    1. Each CAA must maintain a Hazardous Waste Log.
    2. Complete log when waste enters the CAA.
    3. Enter date waste is received in CAA on container hazardous waste label.
    4. This log is used to track hazardous waste generation and establish a waste inventory for waste removal and to confirm our generator status - submit a copy of this log to EH&S prior to hazardous waste shipments.
