The recent revisions to the MCP, most of which became effective June 20, 2014, substantially change how sites with NAPL are characterized and moved through the MCP process.  In addition to some new terminology, MassDEP has embraced the fundamental scientific principles describing the behavior of fluid flow in porous media necessary to assess NAPL in subsurface strata.  PRPs are now asked to provide multiple lines of evidence to support any endpoint conclusions, and MassDEP will be looking for more data than has historically been provided in support of closing out this type of disposal sites.  The NAPL Upper Concentration Limit of 0.5 inches no longer needs to be met, and in fact is no longer available to be used as a component for obtaining an endpoint.

When doing any project, consider whether local Board of Health, Planning Board, Wetlands or other municipal ordinances, bylaws, or regulations could limit or restrict your planned work.  Local rules may impact site cleanup by requiring an additional permit or approval or by imposing stricter requirements.  An unusual case-in-point is a set of regulations adopted by the Town of Dartmouth Board of Health in April 2014 which will have the effect of prohibiting certain types of remediation at properties in Dartmouth, if it withstands judicial scrutiny.  At least one LSP has received an Order to Cease and Desist prohibiting transport of such soils from a property located in Dartmouth being remediated under state cleanup law, bringing the remediation to a halt.

On September 22, 2014, the LSPA sent a letter and submitted comments to MassDEP on its June 2014 Public Review Draft, "Guidance on Implementing Activity and Use Limitations – Policy #WSC14-300". MassDEP is revising its guidance on AULs to accompany the newly amended MCP.

On May 29, 2014 the LSPA Scholarship Fund held its first annual fund-raising golf tournament. Originally conceived of at the annual Past Presidents meeting last summer as a means to raise a targeted amount of $3,500 for the LSPA Scholarship Fund, the tournament actually netted over three times that amount - $11,000 - for the Fund, which celebrates its 10^th anniversary this year.  Over 100 golfers enjoyed a beautiful day, a well-maintained course (Highfields in Grafton), and a hearty post-golf repast.  Prizes were awarded for best-ball team scores and individual skill accomplishments, and a raffle stocked with both golf-related and non-golf related items allowed all the chance to win while supporting the LSPA Scholarship Fund. Photographs of the event, taken by LSPA member and professional photographer Tom Barrasso, are available here.

At the May 8, 2014 LSPA Membership Meeting, the Loss Prevention Committee presented a special program on the complexities of insurance coverage issues at contaminated sites - especially homeowner sites.  This article is intended to provide a brief summary of the issues discussed at the meeting.  Note, it is impossible in this brief article to provide a full discussion of all the relevant issues that come into play in evaluating insurance.  Further, the exact coverage that is provided by a particular policy depends on the language of the policy, and the generalizations discussed at the meeting may not apply.   

Updated TCE Documents

MassDEP has recently made minor revisions to two TCE-related documents (last updated in March, 2014):

• tcestat.doc (360 KB, MS Word)
• tcestat.pdf (764 KB, PDF)

1. EPA Trichloroethylene Toxicity Values and ORS Recommendations Regarding Remediation Targets & Timeframes to Address Potential Developmental Risks (August 15, 2014)

• tcevalsm.doc (245 KB, MS Word)
• tcevalsm.pdf (186 KB, PDF)

Provisions of the Amended MCP are Fully in Effect

LSPA Awards WES Professional Practice Grant to Haley & Aldrich Team

The LSPA is pleased to announce that a WES Professional Practice Grant has been awarded to the Haley & Aldrich team of Richard Rago, Kristina McCarthy, and Jane Parkin Kullman for their  proposal entitled “Background Indoor Air Levels of Volatile Organic Compounds (VOCs) and Air-Phase Petroleum Hydrocarbons (APH) in Office Buildings, Commercial Buildings, and Schools."  This is the first WES Grant awarded since its inception.

Tetrachloroethylene, or PCE, is recognized as a toxic chemical and is considered likely to be carcinogenic in humans by all routes of exposure. The degree of its toxicity has been debated for years, especially for the inhalation route of exposure. Two years ago, the EPA finalized PCE toxicity factors, including an inhalation Unit Risk (UR) factor, which is used to assess carcinogenic risk via inhalation. The LSPA encouraged MassDEP to adopt the EPA toxicity values, including the UR. Instead, during its recent reevaluation of PCE toxicity, MassDEP’s Office of Research and Standards (ORS) relied upon a UR for PCE that it had previously derived.  In January 2014, MassDEP released an updated PCE UR which is lower (i.e., less conservative) than MassDEP’s previously derived value, but remains greater than ten times higher (i.e., more conservative) than the EPA value.
