The Department of Transitional Assistance (DTA) administers SNAP/ food stamps and cash assistance programs in Massachusetts.  Although they do not post most of their sub regulatory materials on their own website, many of these materials can be found in the benefits library section of MassLegalServices.org, including operations memos that are sent to the field, and copies of newsletters reviewing policy and procedure that are sent to the DTA workers.  If you are handling a cash assistance or SNAP case, you can search this section to see if there are any relevant DTA policy materials on your issue.
