Information on Nov. 5, Public Hearing on Draft Air Permit for Air Pollution Control Equipment at Saint-Gobain Performance Plastics and Information Meeting to Provide Update on Southern New Hampshire PFAS Investigation

Information Regarding the November 5, 2019 Public Hearing and Subsequent Information Session

  1. What is the purpose of the public hearing and information sessions?   

There are two events that will be held on the evening of November 5th.

The first event is a public hearing regarding a draft Temporary Permit (draft air permit) that was proposed by the NHDES Air Resources Division on October 4, 2019. The draft air permit would authorize Saint-Gobain Performance Plastics to install equipment to control air emissions of PFAS, as required under NH RSA 125-C:10-e Requirements for Air Emissions of Perfluorinated Compounds Impacting Soil and Water. This event will start at 6:00 p.m.

The second event is a public information session, where NHDES staff will provide an update regarding site investigation activities. NHDES plans to give an (approximately) 30-minute overview, followed by a question and answer session. This event will start approximately 15 minutes after the conclusion of the public hearing for the draft air permit.

2. Details on the Public Hearing – Draft Air Permit

The public hearing is a legal proceeding conducted in accordance with the NH Code of Administrative Rules, Part Env-C 200, Rules of Practice and Procedure, and Part Env-A 200, Procedural Rules. The purpose of this hearing is to receive oral testimony from the public regarding NHDES’ draft decision to issue an air permit as described above.

You may comment on the draft air permit either orally or in writing:

  • Submit oral testimony: You can provide oral testimony at the November 5 public hearing. Similar to rulemaking and legislative hearings, those wishing to provide oral testimony will be asked to fill out a testimony card when entering the hearing room. The cards will be collected at the start of the hearing, and those providing testimony will be called up in the order that the cards are received.

Please note that, depending on the number of people wishing to provide oral testimony, the hearing officer may need to limit the time of each person to ensure everyone has an opportunity to speak. Once everyone who wishes to provide oral testimony has done so, if time allows, NHDES will ask those (who needed more than the initially allotted time) if they wish to provide further oral testimony. While not required, those who provide oral testimony are also encouraged to provide their testimony in writing.

NHDES also wishes to note that if a person provides oral testimony on a particular point, additional testimony that is similar in nature is not necessary. In other words, NHDES evaluates the substance of the comment, whether it is provided by one person or several people.

 Submit written testimony/comments: If you cannot or do not wish to attend the November 5 public hearing, written comments will be received by NHDES at any time prior to 4:00 p.m. on Monday, November 18, 2019. Comments may be sent via mail or email to the following:

NHDES – Air Resources Division
Attn: Catherine Beahm

 3. Details on the Public Information Session on Site Investigation Activities

 Following the conclusion of the public hearing, NHDES staff will provide an update on the Saint-Gobain site investigation activities and the response to assessing drinking water impacts relative to the new Per- and Polyfluoroalkyl Substances (PFAS) drinking water standards (MCLs) and Ambient Groundwater Quality Standards (AGQS). After the presentation, a small panel of NHDES staff will be available to respond to site investigation questions.

Staff from Saint-Gobain’s consultant, Golder Associates, Inc., will be stationed in the hallway outside the meeting room to answer individual questions pertaining to the residential well sampling program and the provision of alternate water.
