MassDEP Releases Interim Guidance on Management of Evaporator Systems Reply

The Massachusetts Department of Environmental Protection (MassDEP) recently published interim guidance for operators of evaporator units that employ a tank or tank system that is used to reduce the volume of (i.e. ,treat ) hazardous industrial wastewater by heating it until it evaporates.

“Evaporator systems,” as used in the interim guidance, are systems that include a wastewater treatment unit (WWTU), an evaporator unit, and all piping ancillary to operation of that system. These systems treat the influent hazardous wastewater to render it non-hazardous, and then evaporate the non-hazardous wastewater in an evaporator unit.

The interim guidance does not apply to:

  • Systems that evaporate only non-hazardous wastewater (generated off-site or on-site)
  • Units that separate non-hazardous wastewater from oil at the site of generation (310 CMR 20.252(4)
  • Units that evaporate non-hazardous wastewater transferred from an elementary neutralization unit at the site of generation (310 CMR 30.1103)
  • Closed –loop vacuum evaporators  that have no air emissions (these are exempt from 310 CMR 30.000)
  • Evaporator systems treating hazardous wastes received from off-site. These require a MassDEP HW facility license (310 CMR 30.801)
  • Sludge dryers associated with WWT systems approved by MassDEP (314 CMR 12.00)
  • Containers or treatment units (other than evaporator systems) subject to MGL 21C and 310 CMR 30.000

Evaporator systems may be exempt from licensing requirements for hazardous waste treatment provided they meet the definition of “treatment which is an integral part of the manufacturing process”. The interim guidelines provide clarification of what is required to maintain the exemption and are intended to give industry an opportunity to evaluate their systems and make necessary adjustments prior to promulgation of the new regulations (anticipated in 2012).

To qualify for the exemption, evaporator systems must:

  • Include a WWTU that is directly connected via permanent piping to the evaporator unit
  • Receive and treat wastewater in the WWTU containing only hazardous constituents in dissolved form (i.e., no multi-phase liquid hazardous waste)
  • Receive and treat wastewaters directly from their dedicated WWTU only
  • Treat the hazardous industrial wastewater in the WWTU so that it is rendered non-hazardous BEFORE it is evaporated
  • Prevent air emissions of hazardous constituents from both the untreated hazardous wastewater and the treated non-hazardous wastewater to the maximum extent practical

In certain cases, operators of evaporator systems that do not meet these requirements may need to obtain a waiver from MassDEP. Here’s the link to the Interim Guidance on Management of Evaporator Systems fact sheet: http://www.mass.gov/dep/recycle/laws/evapguid.pdf

Please be advised, the TURA 2009 Information Release is now available on line at the following site:

 http://www.mass.gov/dep/toxics/tura/turadata.htm

The data show that even after accounting for changes in production levels,Massachusetts is continuing to make progress in Toxics Use Reduction!

Please remember that the final step in TURA filing is submitting your payment to the Massachusetts Department of Environmental Protection (MassDEP).  Toxics Use Fees are due to MassDEP by September 1st.  This is different from the information on the Toxics Use Fee Worksheet.  No bills will be sent out this year.  If payment is not received by September 1st , a bill will be send out with a $1,000 late fee.

MassDEP to Finalize UST Operator Training Requirements Regulations 310 CMR 80.00 Reply

Federal regulations for owners and operators of Underground Storage Tanks (UST’s) require that facilities must have certified operators for their UST systems by August 8th, 2012.  To satisfy the federal regulation, the Massachusetts Department of Environmental Protection (MassDEP) has developed an emergency regulation, 310 CMR 80.00 Operator Training, which outlines the requirements of owner and operators of UST’s and the MassDEP requirements. 

Facilities will be allowed to train operators internally to meet the training requirements and will also be required to have a Class A, B, and C Operator on staff at the facility.  In addition to the internal training, Class A and B Operators will be required to pass an exam administered by the MassDEP and pay the associated registration fees.  It is important to note that one person may serve as the Class A, B and C Operator for a facility, but certification must be obtained by the August 2012 deadline.  

For more information regarding this emergency regulation, the public comment period, or the requirements for each class of operator please see the links below or contact Josh Fawson at 508.970.0033 x120 or jfawson@capaccio.com..

Proposed Regulation 310 CMR 80.00

New Regulatory Vapor Intrusion Guidance Reply

ThroughoutMassachusetts, releases of materials containing volatile organic compounds (e.g., petroleum products, dry cleaning fluids, industrial solvents) have impacted soil and/or groundwater.  When these releases occur near buildings, volatilization of contaminants in the subsurface can result in the intrusion of vapor-phase contaminants into indoor air spaces and can pose a risk to workers and other building occupants.

In June 2010, the American Society for Testing and Materials (ASTM) updated its Standard Practice for Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions (E2600-10).  This guide defines a procedure to identify, during a Phase I property assessment, whether a vapor intrusion condition exists, likely exists, cannot be ruled out, or can be ruled out because a vapor intrusion condition does not or is not likely to exist.

In response to the regulated community’s questions and concerns, in December 2010, the Massachusetts Department of Environmental Protection (MassDEP) issued an Interim Draft Vapor Intrusion Guidance document to provide regulatory guidance on assessing and mitigating vapor intrusion pathways at sites regulated by the Massachusetts Contingency Plan (MCP). This document addresses approaches to the assessment and remediation of vapor intrusion in order to maintain compliance and eventual site closure within the MCP.

Both the ASTM guide and the MassDEP guidance documents can be applied to property with existing structures, property with structures that will be substantially rehabilitated, property without existing structures but having planned structures (e.g.,, property in development), or property without existing structures and with no planned structures (e.g.,, undeveloped property with no planned development).

Following receipt of public comments, due by March 1, 2011, the MassDEP will finalize the Vapor Intrusion Guidance document.  If you have a concern about the potential for your existing or planned property to have a vapor intrusion impact, call Dawn Horter at 508.970.0033 ext. 118.
