Disposal Reporting System Overview by panniuniu


									   Focused Workshop on the
Informal Draft Revised Disposal
 Reporting System Regulations
          Session #2:

   Transfer Station Issues

            March 2003
Workshop Agenda
 Introduction
 Weighing loads at transfer stations
 Tracking origin information at transfer
 Reporting allocation information to other
  disposal facilities
 Other transfer station issues

Workshop Purpose
   Gather information on current transfer station
   Gain a better understanding of how transfer stations
    will operate under revised regulations given the
    increasing amount of waste going through transfer
    stations for delivery to regional landfills
   Obtain input on specific sub-topics of the DRS
    regulations as they relate to transfer stations:
        Focus on solutions
        Consider alternatives to implement Board-approved
         SB 2202 recommendations

Brief Overview of Current DRS
   Station operators are required to maintain
    DRS records for three years and allow
    affected parties to audit records
   Operators must conduct jurisdiction of
    origin surveys for every load during a
    minimum one-week per quarter period
   Station operators determine allocations
    for each jurisdiction and provide receiving
    facility operators with this information
Brief Overview of Current DRS
   Station operators provide receiving
    operators with the jurisdiction of origin
    and material types for materials identified
    as potential ADC or AIC
   Operators send agencies reports on
    amounts of waste exported out of state,
    allocated to each jurisdiction

Weighing Loads at
Transfer Stations

    Weighing Incoming/Outgoing
   Concerns with existing system:
       Tonnage data may not be accurate, since many
        facilities do not have scales and many use different
        conversion factors to estimate weight
       Transfer truck weights determined at transfer
        stations differ from weights obtained at the landfill,
        often resulting in allocation difficulties
   SB 2202 recommendation to address the concerns:
       Require scales and weighing of all loads at facilities
        above a certain tonnage per day. Allow exemptions
        for rural facilities
       The Board should require standards for collecting
        tonnage information                                      7
Weighing Incoming/Outgoing
   1st informal draft regulations
       Stations with scales must weigh all loads
       A station is required to have scales if accepting
        >100 tons per day (based on an annual average)
       Station operators are required to report “initial
        estimated tons of waste sent to each facility” in
        quarterly notifications to other facility operators
   Alternative methods?

Tracking Origin Information at
      Transfer Stations

Origin Survey Frequency
   Concern with existing system:
       Extrapolating tonnage allocations using one week of
        origin survey data per quarter reduces accuracy of
        quarterly tonnage allocations, particularly for smaller
   SB 2202 recommendation to address the concern:
       Require daily surveys
       Exempt self-haul loads delivered in cars and pickup
        trucks from daily surveys because the amount of
        waste is relatively small (Self-haul waste delivered to
        disposal facilities in these vehicle types was
        estimated at only 3% of statewide disposal in 1999)
Origin Survey Frequency
   1st informal draft regulations
       Daily surveys of all loads with the following
        possible exceptions:
         • One week per quarter surveys of some self-haul
         • Assign all waste to host jurisdiction if authorized
           by the host jurisdiction
         • Rural facilities may conduct one week surveys for
           all waste
   Alternative methods?

Collecting Origin Data from Haulers
   Concerns with existing system:
       Drivers are typically the ones responsible for
        providing gate attendants with origin information
       Due a variety of factors, driver reported information
        may be inaccurate
       Self-haul allocations are difficult to verify

   SB 2202 recommendation to address the concerns:
       Require commercial haulers to provide origin data
        based on dispatch records
       Require new, standardized information to be
        collected from self-haul customers
Collecting Origin Data from Haulers
   1st informal draft regulations
       Commercial haulers:
         • Obtain origin allocations based on dispatcher reported
       Commercial self-haulers:
         • Obtain waste origin information, including jurisdiction and
           address from which waste was collected from driver
         • Record origin information on forms
       Residential self-haulers:
         • Obtain jurisdiction of origin information from driver at gate
   Alternative methods?

Determining Origin of Mixed Loads
Sent From Stations
   Concern with existing system:
       Jurisdiction allocations within mixed transfer truck
        loads are difficult to determine
       Allocations based on amounts accepted at the gate
        may not fairly reflect a jurisdiction’s recycling efforts
   SB 2202 recommendation to address the concern:
       Require statewide standards for collecting origin and
        disposal tonnage information

Determining Origin of Mixed Loads
Sent From Stations
   1st informal draft regulations
       Disposal:
         • Allocate to jurisdictions based on total tons
           received from each jurisdiction, or
         • Allocate based on total tons from each jurisdiction
           after adjusting for diversion at the station
       Diversion:
         • Inform a receiving operator of jurisdictions of
           origin for materials identified as potential ADC,
           AIC, and beneficial use material on a daily basis
   Alternative methods?
Reporting Allocation Information
to Other Stations, Landfills, and
Transformation Facilities

Frequency and Timing of Reporting
   1st informal draft regulations
       Provide ADC, AIC, and beneficial use allocation
        information daily, and
       Provide disposal allocation information daily or
        quarterly, but no later than two weeks* after the
        end of the quarter
   Alternative methods?

* This time frame will be changed back to four weeks in the
    next draft regulations to allow two weeks for haulers to
    provide information to the station.
Notification to Facilities
   1st informal draft regulations
        Quarterly notification to be sent to all facilities,
         agencies, and jurisdictions* including:
          • Information on amounts sent to each facility, and
          • Jurisdiction allocations for the quarter
        No specified format for notification--electronic or
         paper files
   Alternative methods?
*   The next draft regulations will likely make the reports to
    jurisdictions “upon jurisdiction request” rather than
    mandatory for all.
Other Transfer Station Issues
   Tracking and reporting of waste that overlaps
    two quarters (i.e., waste leftover on tipping
    room floor at the end of the day on the last day
    of the quarter)
   Potential effect of rail haul on station operations
   Other???

Next Steps in Regulations
   Revise first informal draft regulations based on
    written comments and input from the December
    and March workshops
   Second informal draft regulations will be sent
    out for review and comment
   Schedule workshops on second informal draft
