Focused Workshop on the Informal Draft Revised Disposal Reporting System

Regulations Session #2:

Transfer Station Issues

2

Workshop Agenda

Introduction Weighing loads at transfer stations Tracking origin information at

transfer stations Reporting allocation information to

other disposal facilities Other transfer station issues

3

Workshop Purpose Gather information on current transfer station

practices 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

4

Brief Overview of Current DRS Regulations 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

5

Brief Overview of Current DRS Regulations

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

6

Weighing Loads atTransfer Stations

7

Weighing Incoming/Outgoing Loads

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

8

Weighing Incoming/Outgoing Loads

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?

9

Tracking Origin Information at

Transfer Stations

10

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 jurisdictions

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)

11

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 loads• Assign all waste to host jurisdiction if

authorized by the host jurisdiction• Rural facilities may conduct one week

surveys for all waste Alternative methods?

12

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

13

Collecting Origin Data from Haulers 1st informal draft regulations

Commercial haulers:• Obtain origin allocations based on dispatcher reported

information 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 house

Alternative methods?

14

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

15

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?

16

Reporting Allocation Information to Other Stations, Landfills, and Transformation Facilities

17

Frequency and Timing of Reporting Allocations

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.

18

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.

19

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???

20

Next Steps in Regulations Process 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 regulations
