Petroleum Technical Assistance Program

PLIA is implementing an expanded technical assistance program to include qualifying petroleum storage tanks (formerly the program was limited to heating oil tanks). Beginning January 2018, PTAP will offer customers technical assistance and written opinions on whether a cleanup has met the state’s requirements. The program is available for customers who conduct cleanups of qualifying petroleum contaminated sites. The types of opinions provided include:

  • No Further Action (NFA) on the Site/Property.
  • Further Action (FA) on the Site/Property.
  • Partial Sufficiency (PS) of the cleanup.

Applications for PTAP will not be accepted before January 2, 2018.
