Inc. 122 Quincy Shore Drive Quincy, MA 02171 Re: Authorization to discharge under the Remediation General Permit (RGP) - MAG910000. Harvard Kennedy School site located at 79 John F. Kennedy Street, Cambridge, MA 02138­ 0000, Middlesex County; Authorization# MAG91 0668 Dear Mr. Pennie: Based on the review ofa Notice ofIntent (NOI) submitted by Elizabeth J. Christmas from Haley & Aldrich on behalfofthe Fellows ofHarvard College, acting by and through Harvard Kennedy School, 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/region 1/ npdes/mass.html#dgp. Please note the enclosed checklist includes the pollutants total suspended solids (TSS) and iron which your consultant marked " Believed Present" . Ifthis information changes during the clean­ up operations an adjustment on the list ofthe monitoring parameters is required using a notice of change (NOC). Also, please note that the metal iron (the only metal reported) is included on the checklist, this is a dilution dependent pollutant and subject to limitations based on selected dilution ranges and technology-based ceiling limitations. For this parameter the dilution factor 27 for this site is within a dilution range greater than ten to fifty (>10 to 50), established in the RGP. (See the RGP Appendix N for Massachusetts facilities). Therefore, the limits for iron of5,000 ug/L, is required to achieve permit compliance at your site. Finally, please note the checklist ofpollutants attached to this authorization is subject to a recertification because the operations at the site will result in a discharge lasting longer than six months. A recertification can be submitted to EPA within six (6) to twelve (12) months of operations in accordance with the 2010 RGP regulations. This general permit and authorization to discharge will expire on September 9, 2015 . You have reported this project will terminate on April 1, 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 indicated on the EPA website after the EPA Permit is reissued. Also, you are required to submit a Notice ofTermination (NOT) to the attention ofthe contact person indicated below within 30 days ofproject completion. Thank you in advance for your cooperation in this matter. Please contact Victor Alvarez at 61 7-9 I 8­ 1572 or [email protected], if you have any questions.
