UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Region 1 5 Post Office Square, Suite 100 BOSTON, MA 02109-3912 CERTIFIED MAIL RETURN RECEIPT REQUESTED MAR l. 5 2015 . Thomas J. Walsh Project Manager Bond Brothers 145 Spring Street Everett, MA 02149 Re: Authorization to discharge under the Remediation General Permit (RGP)- MAG910000. Massachusetts Institute ofTechnology (MIT), Area 5 and Proposed Central Utility Plant (CUP), sites located on MIT Campus (behind MIT building 44 and 50 Albany Street respectively), in Cambridge, MA, Middlesex County; Authorization # MAG91 0670 Dear Mr. Walsh: Based on the review ofa Notice ofIntent (NOI) submitted by Sandhya N. Potana from Haley & Aldrich on behalfofMIT for the site referenced above, the U.S. Environmental Protection Agency (EPA) hereby authorizes you, as the named Operator to discharge in accordance with the provisions ofthe RGP at that site. Your authorization number is listed above. The checklist enclosed with this RGP authorization indicates the pollutants which you are required to monitor. Also indicated on the checklist are the effluent limits, test methods and minimum levels (MLs) for each pollutant. Please note that the checklist does not represent the complete requirements ofthe RGP. Operators must comply with all ofthe applicable requirements ofthis permit, including influent and effluent monitoring, narrative water quality standards, record keeping, and reporting requirements, found in Parts I and II, and Appendices I -VIII ofthe RGP. See EPA's website for the complete RGP and other information at: http://www.epa.gov/regionl/npdes/mass.html#dgp. Please note the enclosed checklist includes parameters which your consultant marked "Believed Present". Group I and group II list ofpolycyclic aromatic hydrocarbons (P AHs) were also included due to their historic presence at the_site. Also, please note that the metals included on the checklist are dilution dependent pollutants and subject to limitations based on a dilution factor range (DFR), due to the ample dilution at the point ofdischarge (71.3) the DFR applicable for this pollutant is within a dilution range greater than fifty to one hundred (>50-100) established in the RGP. (See the RGP Appendix IV for Massachusetts facilities). Therefore, the limit for antimony of 141 ug!L, arsenic of500 ug/L, cadmium of 10 ug!L, trivalent chromium of 1,710 ug/L, copper of260 ug/L, lead of66 ug!L, zinc of 1,480 ug/L and iron of5, 000 ug/L, shall not be exceeded in the discharge. Finally, please note the checklist ofpollutants attached to this authorization is subject to a recertification ifthe operations at the site result in a discharge lasting longer than six months. A recertification can be submitted to EPA within six (6) to twelve (12) months ofoperations in accordance with the 2010 RGP regulations. This general permit and authorization to discharge will expire on September 9, 2015. You have reported that this project will terminate on March 15, 2017. Please be advised that in order for the site to continue discharging after the expiration date indicated above your consultant must seek a permit reissuance. A reapplication and reissuance notice will be posted on the EPA website after the EPA permit is reissued. · Also, you are required to submit a notice oftermination (N01) to the attention ofthe contact person indicated above within 30 days ofproject completion. Thank you in advance for your cooperation in this matter. Please contact Victor Alvarez at 617-918 1572 or [email protected], ifyou have any questions. Sincerely, !luJ,'1\. {\_ r11.MA{Yo/ .
