The Waste Site Cleanup Advisory Committee provides input to the Department of Environmental Protection (MassDEP) on waste site cleanup regulations, policies and programs. In addition, the Committee serves as a forum for keeping interested organizations and individuals up to date on related MassDEP activities

Meeting Agendas, Materials and Minutes

The meeting agenda is generally posted one week prior to the meeting date and provides information on the time and location of the meeting. Electronic versions of the handouts distributed at the Advisory Committee meeting will be made available as soon after the meeting as feasible and for up to one year. Links to such material appear at the bottom of each agenda.

Upcoming Meetings

NEXT WASTE SITE CLEANUP ADVISORY COMMITTEE MEETING:  Thursday, June 22, 2017, 9:30 am to 12:00 pm at MassDEP’s Boston Office, One Winter Street, 2nd floor. 

If you are unable to attend in person, the meeting is available via live-streaming at https://www.youtube.com/channel/UCswijd-Vuwa0jMR4EroSm8w/live

The agenda includes:

  • General program updates, including MassDEP website and data portal
  • TCE sites updates
  • PFAS toxicity considerations
  • Natural Resource Damages program updates
  • Clean Energy updates
  • MCP Amendments―focused on Temporary Solutions and associated requirements/submittals.  See discussion guide below.

 

MCP Temporary Solution amendments discussion objective: Evaluate requirements for disposal sites for which Temporary Solutions are achieved (both types―where a Permanent Solution Feasible, and where a Permanent Solution Infeasible) specifically related to tier classification and tier classification extensions, periodic review, status reports and remedial monitoring reports.  There is vagueness and some inconsistency in the current provisions.  The goal of amendments would be to make the submittal requirements (type and frequency) clear and appropriate for the nature of response actions that are occurring at such sites.

 

Discussion questions (to gain insight into the different ways disposal sites with Temporary Solutions are being managed):

  1. What types of actions are completed after a Temporary Solution to achieve a Permanent Solution?
  2. For Temporary Solution sites, what are the barriers remaining to achieve a Permanent Solution? 
  3. What is the purpose of collecting groundwater samples for sites after a Temporary Solution is achieved?
  4. What is the typical interval for groundwater monitoring (not related to MNA, which is considered an Active Remedial Monitoring Program) for sites with a Temporary Solution?
  5. Should six month Status reports be required for groundwater monitoring at Temporary Solution sites?  Annual Status Reports?
  6. Are there Temporary Solutions (PS is Feasible) where no ongoing remedial actions are being completed?
  7. Do LSPs track due dates for 5-Year Periodic Reviews of Temporary Solution?
  8. Should a valid Tier Classification be required for disposal sites with a Temporary Solution where no remedial actions are currently being conducted? For sites that achieve a Temporary Solution, there are no deadlines for next steps (other than the 5 year Periodic Review where a PS is Infeasible).  If a PS is Feasible, what should be the deadline for implementing the remedy?
  9. For sites that achieve a Temporary Solution, there are no deadlines for next steps (other than the 5 year Periodic Review where a PS is Infeasible).  If a PS is Feasible, what should be the deadline for implementing the remedy?

 

* MCP Amendments discussion focused on Exposure Point Concentration provisions(310 CMR 40.0926): Friday, June 23, 2017, 10 am to 12 pm at MassDEP’s Boston Office, One Winter Street, 2nd floor.  

 

Topics will include:

  • The objectives of revising the EPC section
  • Concurrent guidance revision plans
  • Discussion of sampling and data analysis issues for relatively complex sites
    • Possible minimum data set size,
    • Use of Upper confidence limit (UCL) on the mean to estimate the mean, selecting the appropriate UCL method, appropriate UCL percent level
  • Review and comparison of ProUCL output for sample data sets
