Maine’s Experience

MAINE DEPARTMENT OF ENVIRONMENTAL PROTECTION

Protecting Maine’s Air, Land and Water

David Burns, P.E. Acting Director Bureau of Remediation & Waste Management

Actions Taken Through 5/15/2019

• April 2, 2017 – DEP established a

hierarchy to prioritize investigation of PFAS in drinking water

• Developed SOP for sampling and analysis
• f PFAS
• Utilizing EPA’s 70 ppt health advisory level

for drinking water supplies

• Established meetings with Maine’s

Drinking Water Program staff

MAINE DEPARTMENT OF ENVIRONMENTAL PROTECTION www.maine.gov/dep

Actions Taken Through 5/15/2019

• PFAS testing:

– active remediation sites where drinking water is known to be impacted and the Department suspects PFAS may be present at the source due to site history – remediation sites with potential at-risk drinking water supplies – prior to closing out sites that have been otherwise remediated and a risk factor exists – Biosolids associated with land application or composting – EPA 5-year review sites

MAINE DEPARTMENT OF ENVIRONMENTAL PROTECTION www.maine.gov/dep

Actions Taken Through 5/15/2019

• Worked with ME CDC to evaluate risk by

establishing screening levels as well as to evaluate risk at individual remediation sites.

• In conjunction with ME CDC, established limited

PFAS screening levels in RAGs and Chapter 418 (PFOA, PFOS, & PFBS)

• Discussing ways to inventory AFFF stockpiles in

Maine to determine extent. Firefighting foam use and associated MDEP response

Case Study – Corinna Landfill

• March 22, 2019 letter to facilities that

compost or land apply biosolids

• Through 5/17, received results from 40% of

facilities required to report. Expect most results will be submitted sometime in June

• Results compared to Ch. 418 Appendix A

Biosolids Testing Requirement

• States have set or proposed MCLs (includes

NJ, NY, VT, NC, NH) or various health advisories

• States have listed PFAS as hazardous

substances (includes VT, NY, NJ)

• New Jersey directive to manufacturers

– https://www.nj.gov/dep/docs/statewide-pfas-directive-20190325.pdf

• https://pfas-1.itrcweb.org/fact-sheets/

State Responses

• Limited authority available under Chapters

418 & 419 of solid waste rules (PFOA, PFOS, PFBS)

• Stakeholder process to modify Chapter 800 to

list PFAS compounds as hazardous matter.

• Air Bureau authority under 38 MRS 585-B to

establish standards or work practices for HAPs

• Water Bureau – Chapters 521 & 523

MDEP Regulatory Authority

Sampling, Analysis, & Remediation Funding

• Money expended to date mostly related to

solid waste work and remediation sites

• Funding authority when PFAS compounds

are the only known contaminant?

• Measured approach to date, have been able

to absorb costs within existing budgets

• Future funding mechanisms?
