File Review Procedures

Appointments are required. You may request up to 6 files (not sites - 3 file numbers constitutes 3 of the 6 files) during one appointment. The request should be organized and complete to ensure that the correct files are provided, so please research your site(s) before requesting an appointment.

Appointments are only established once you receive a confirmation from the Service Center. If the Service Center does not respond to your inquiry within a reasonable time, please re-submit your request.

Seats are limited and customers are served on a first come - first served basis.

Upon arrival, please read and fill out the form supplied to you by the Service Center and return it to the File Manager on duty before leaving.

During review, DO NOT unclip, remove staples, or take binders or folders apart.

Photo copies and faxes are available for 20 cents per 8" x 11" page. Fees vary for other size pages.

Only checks will be accepted and should be made payable to Commonwealth of Massachusetts. There is a $20 fee for returned checks.

Arrangements can be made to have files sent out to a copy service, which is recommended for any large documents. When there are several people requesting copies, DEP staff have priority for using DEP copy machines.

If you are unable to keep your appointed time, you must call and cancel your appointment by 12 noon the previous working day. A fee may be billed to your company for appointments which are not appropriately canceled.

NOTE: You can also download site lists from MassDEP's Website.

Regional Profile 

This region, which spans from the Connecticut border to the New Hampshire line, encompasses all of Worcester county and includes some municipalities in western Middlesex and Norfolk counties. In all, there are 77 towns and cities with a total population of nearly 900,000.

Most communities in the Central Region grew up around mills, many of which have since given way to high tech companies and various support industries. The region still hosts a number of metal fabricating and plating firms, plastics manufacturers and remnants of the paper, shoe and furniture industries. A few large farms dot the landscape, but agriculture has slowly been replaced by residential and commercial development.

The major river basins (Blackstone, Nashua, Concord, Merrimack, Chicopee, French and Quinebaug, and Millers) as well as the Wachusett Reservoir and its watershed are among the chief natural features of the Central region.
