The Massachusetts Department of Environmental Protection (MassDEP) promulgated new sewer system extension and connection regulations (314 CMR 7.00) in 2007. These regulations required industrial facilities with wastewater discharges above certain thresholds to apply for a permit, submit a self-certification, or be considered “Permit by Rule” which does not require a submittal. The following thresholds determine what actions must be taken:
You discharge to an EPA approved industrial pretreatment program (IPP) and your combined discharge (industrial and sanitary) is greater than 50,000 gallons per day (gpd) – Apply for Permit
You discharge to an EPA approved IPP and your combined discharge (industrial and sanitary) is less than 50,000 gpd – Permit by Rule
You discharge to a non approved IPP and your combined discharge (industrial and sanitary) is greater than 25,000 gpd – Apply for Permit
You discharge to a non approved IPP and your combined discharge (industrial and sanitary) is less than 25,000 gpd – Submit a Compliance Certification
Both the permit and the self-certification are valid for 5 years. With the majority of the final permits and certifications being issued and approved in early 2008 many industries will be required to renew their permits or certifications towards the end of this year.
The permit renewal process is the same as the process completed to obtain the original permit. Permit renewal applications (BWP IW 38 or 39) must be submitted 90 days prior to the expiration of the existing permit and companies will again be required to complete the public notification process. Self-certifications must be submitted before the existing certification expires and do not require any public notification.
