The engineering plans consist of six sheets the first of which is titled: Interim Septage Receiving Facility South Essex Sewerage District Salem Massachusetts Tighe and Bond Consulting Engineers Michael R. Parsons Registered Professional Engineer (Mass. No. 29270) The proposed modifications include the fabrication and installation of a new septage receiving and receiving chamber and the installation of all piping, valves, and connections. The modifications also include furnishing and installing control and alarm systems and a sampling system and the required electrical interfacing with the proposed keycard verification system. In addition, construction of a spill containment area and the regrading of the paving area outside the garage bay area are included in the work to be performed. The system was designed with sufficient capacity to handle maximum monthly loadings of 900,000 gallons per month of hauled wastes. The Department has reviewed the plans and specifications for the referenced project and is of the opinion that they have been prepared in accordance with modern sanitary engineering practice and hereby approves them subject to the following conditions: (1) The interim septage receiving area shall be operated without causing an odor nuisance. One Winter Street • Boston, Massachusetts 02108 0 FAX (617) 556.1049 • Telephone (617) 292.5500 y (2) An interim Operation and Maintenance (0 and M) Manual shall be submitted to the Department for review and approval prior to completion of construction of the interim septage receiving facility. The 0 and M Manual shall be prepared in accordance with 314 CMR 12.00 and shall also include a schedule for deliveries of septage and other procedures to minimize the generation of odors from the receiving facility. Provisions for the use of chemical addition to inhibit odor generation shall also be described in detail. (3) Approval of the septage receiving area to be constructed is strictly on an interim basis. South Essex Sewerage District is currently involved in a facilities planning process that addresses among other things, residuals handling at the facility. The recommendations from the facilities planning process as approved or modified by the Department, shall take precedence over the interim modifications. Specifically, modifications such as addition of flow equalization at the septage receiving area, modifications in chemicals available for usage, and changes in the system of handling water treatment sludges and grease trap pumpings may be forthcoming. SESD should be advised that approval of this interim modification should not in any way be deemed to imply approval of the interim system, or any part of it, on a long term basis. (4) A plan for minimizing the potential for odor generation for the period prior to completion of construction of this project shall be submitted to the Division of Water Pollution Control, Northeast Regional Office for review and approval, by March 26, 1992. The plan shall include a description of present operating procedures and limits on volumes of septage to be received. The plan shall also address whether or not installation of a temporary quick -connect pipe, to be used until the interim modifications are completed, is feasible. If you have any questions please contact Thomas Mahin at 556 - 1065. Very truly yours, Paul A. Taurasi, P.E.

Item 4 requires the District to submit a plan for minimizing the potential for odor generation while the proposed facilities are under construction. This letter is beine submitted by facsimile in order to meet the submittal date in your letter. The Item 4 comment is as follows: (4) A plan for minimizing the potential for odor generation for the period prior to completion of construction of this project shall be submitted to the Division of Water Pollution Control, Northeast Regional office for review and approval, by March 26, 1992. The plan shall include a description of present operating procedures and limits on volumes of septage to be received. The plan shall also address whether or not installation of a temporary quick -connect pipe, to be used until the interim modifications are completed. is feasible. This response has been prepared to provide you with the requested plan including the three , lh ^ments you OL"w^.ed: i) present operating procedures; — ilriliiS On volume of Septage LU Oe received; and 3) feasibility of a temporary quick -connect pipe. 1. Operating Procedures - The present operating procedures utilized by the District for the receipt of septage and other hauled wastes generated within the District are listed on Attachment A. In addition to the standard operating procedures. septage will be received only at the existing septage hopper inside the Grit Building until the Project has been constructed. After the Project is operational. septage deliveries will only be accepted at the new facilities. The District will not allow the discharge of septage into inanhoie structures at the Wastewater Treatment Plant. _. Limit on Volume Received - Until completion of construction. the receipt or sernaee will be limited to the hours of 8 AM to 3 PM. Monday through Friday. unless an ann i4' Powers 3onaid A. dfichaiski Jenna h'. 3mncnt .'dark I Hoeu :menti David G. N.eaieu lfichael R. P .Ions '_.nes S. O Reil(u -caa Sf.

The purpose in limiting the hours in which septage is received is to confine the operation to the period when SESD staff is best able to monitor the septage haulers during construction of the Project. In addition. limiting the total amount of time for septage deliveries will provide additional control on the total quantity of septage to be received at the District. This time period will allow the District to accommodate a maximum of 20 deliveries in a day. I Temporary Connection - SESD has also considered a temporary connection as suggested in your February 24, 1992 approval letter. The concept of a temporary arrangement might cause new operational problems in an attempt to minimize the potential release of odors from the Grit Building during septage delivery. Our concent of a tempnrnty co—action is the installation of a 4 �� Cr �,n ':a....,ter pip.^. yr hose across the Grit Building floor and through one of the overhead doors. This arrangement is not feasible because the slope of the existing pavement in front of the truck doors would preclude the trucks from emptying. This arrangement is also not feasible because it would result in a connection point outside the Grit Building that would be too high for some of the delivery trucks. Also. the disconnection of trucks would likely result in spilling septage from the hose connection onto the ground in a location where there is not a drain for effective cleanup. For these reasons the SESD has concluded that the installation of a temporary exterior connection is not feasible. In addition to the three items discussed above, SESD plans to expedite related construction work for the purpose of reducing potential odor emissions associated with the delivery of septage: 1. Proposed Facility Modifications - The proposed facility modifications which were approved by the Department are intended to minimize the potential for the release of odors associated with the delivery of septage. In order to make the proposed facilities available as soon as possible, the construction contract has two completion dates. The interim completion date is June 21, 1992, by which time the contractor is required to have the proposed facility installed and available for manual operation. The final completion date is July 21, 1992, by which time the entire fac�Hty shall be completely operat.onal, including the alarm systems, sampler, chemical feed system. and related controls. 2. Grit Buildin Ventilation System - Under a separate on-going contract (No. 92- 1) for improvements to the heating and ventilating system, a hood. duct work, wall extensions, and a plastic curtain will be installed over the existing septage receiving hopper. The purpose of these improvements is to collect and convey air in the vicinity of the hopper and discharge it to Odor Control Unit A. SESD will attempt to expedite this portion of Contract 92-1 so that it is available as soon as possible prior to the contract completion date of June 6. 1992. Conclusion - As stated at the beginning of this letter. the District considers this entire letter to be its plan for minimizing the potential for odor generation for the period prior to completion Tighe&Bona Consult-=- Er.nnec7s rtironmen=; Snecialisx of construction of the Project. We hope that the items discussed in this letter and in the attachment adequately address the comments raised in Item 4 of your February 24. 1992 letter. If you have any questions regarding this response. please do not hesitate to contact SESD or the undersizned. Very, truly yours, TIGHE & BOND. INC. Michael R. Parsons.

The Department's Regulations, 310 CMR 19.000, do not provide for the Department to "approve" a generator of solid wastes to dispose of that waste at a specific, facility. Pursuant to 310 CMR 19.061, Special waste, the Department's authority is to assess the suitability of a waste for disposal at a solid waste facility and establish any special handling which may be needed to insure the safe and nuisance free disposal of the waste, and ensure that the landfill is capable of providing such special handling when required., An application for .approval of the disposal of a special Waste at a specific facility can only be submitted by the -disposal facility. should you wish for the Department to review the specific characteristics of your waste to assess its classification under 310 CMR 19.061 it will be necessary for you to submit an application for a Special Waste Determination pursuant to the requirements set forth at 310 CMR 19.061(4). Such an application is subject to the filing and fees requirements of 310 CMR 4.00. Under the Department's current policy regarding the disposal of grit and screenings from the headworks of municipal waste water treatment facilities, these materials are not classified as'Special wastes unless an unusual condition has resulted in the contamination of the grit and screenings in a manner not normally encountered in the operation of the facility. As such it is the Department's opinion at this time, that the grit and screenings from the SESD waste water treatment facility are not a Special Waste and thus do not require the approval of the Department for disposal at the GCR landfill in Peabody. The Department reserves the right to amend, modify or rescind this decision as may be appropriate to protect the public health, safety or tfie environment or as otherwise necessary pursuant to the law and regulation. 10 Commerce Way • Woburn, Massachusetts 01801 0 FAX (617) 935-6393 9 Telephone (617) 935-2160 r ... .. .y 5 .... ..

September 26, 1988 Re: SALEM - Metropolitan Boston/ Northeast Region 310 CMR 7.02 - Plans Approval Application No. MBR -88 -IND -126 CONDITIONAL APPROVAL Attention: Mr. Richard K. Perna, Executive Director Gentlemen: The Metropolitan Boston/Northeast Region of the Department of Environmental Quality Engineering, in response to the series of items received from Camp, Dresser and McKee, Incorporated on April 20, 1988 through June 30, 1988, has reviewed the plans and specifications relative to the proposed installation of an odor control system at your 50 Fort Avenue, Salem, Massachusetts facility. The submitted information bears the seal and signature of Mr. Robert J. Gaudes, Massachusetts P.E. No. 32462. This review of the submitted information by Department engineers discloses that the proposed project involves the installation of six packed tower scrubbing systems. Two scrubbing systems will be used to control odors from the existing grit building, designated as Scrubber Facility A, while the remaining four scrubber systems will be employed to control odors from the residuals treatment building, designated as Scrubber Facility B. Scrubber Facility A will be employed to control hydrogen sulfide emissions generated by the existing grit building. Scrubber Facility A will consist of two Ceilcote, or equivalent, single stage counter -flow packed bed scrubbers in series, each having a maximum air handling capacity of 39,000 scfm. Each scrubber will be equipped with a Ceilcote Model No. CMHB-48, fiberglass centrifugal fan having a maximum rated capacity of 39,000 standard cubic feet per minute (scfm). The proposed scrubbers will each spray a recirculated scrubber liquor at a rate of 390 gallons per minute at a pressure of 100 pounds South Essex Sewerage District page 2 per square inch water gauge (psig) onto 78.5 square feet of polypropylene tellerette packing. Each scrubber will be equipped with an automatic pH controller and an automatic chemical make-up feed system (ORP). Make-up water for each scrubber will be provided to the recirculated scrubber liquor at a maximum delivery rate of 20 gallons per minute. An audible alarm system will signal any system upsets. The first scrubber in the Scrubber Facility A tandem system will employ a sodium hydroxide_ scrubbing liquor with a pH maintained at approximately 10 by the automatic addition of a 15 percent sodium hydroxide solution. The second scrubber in this systein will employ a sodium hypochlorite scrubber liquor and will be maintained at an Oxidation/Reduction Potential to optimize scrubber efficiency (to be determined at a later date) by the automatic addition of a 30 percent sodium hypochlorite solution. Scrubber Facility A is expected to have an overall control efficiency of 88 percent, which will reduce the maximum hydrogen sulfide mass emission rate of 0.894 pounds per hour to 0.103 pounds per hour. jThe exhaust air from Scrubber Facility A will be discharged through a vertical stack,, the top of which will be 39 feet above ground level. The inside exit diameter of the stack will be 3.5 feet, which will provide an exit velocity of 33 feet per second at 85° F. Scrubber Facility B will be employed to ventilate_ the plant's residuals handling facility and will consist of two parallel trains of two Ceilcote, or equivalent, single stage counter -flow packed bed scrubbers in series. Each scrubber will have a maximum air handling capacity of 33,500 scfm for a total facility ventilation flow rate of 67,000 scfm. Each scrubber will be equipped with a Ceilcote Model No. CMHB-48 centrifugal fan having a maximum rated capacity of 33,500 scfm. The proposed scrubbers will each spray a recirculated scrubber liquor at a rate of 335 gallons per minute at a pressure of 100 psig onto 78.5 square feet of polypropylene tellerette packing. Each scrubber will also be equipped with an automatic pH controller and a chemical make-up feed system (ORP). Make-up water for each scrubber will be provided to the recirculated scrubber liquor at a maximum delivery rate of 20 gallons per minute. An audible alarm system will signal any system upsets. Each of Scrubber Facility B's tandern scrubber train will be operated as described for Facility A. Each of Scrubber Facility B's odor control trains is expected to have an overall control efficiency of 90 percent, which will reduce their maximum hydrogen sulfide mass emission rates of 1.777 pounds per hour to 0.177 pounds per hour. Soutli Essex Sewerage District page 3 Each scrubber system train's exhaust air will be discharged through a vertical stack, the top of which will be 39 feet above ground level. The inside exit diameter of the stack will be 3.5 feet, which will provide an exit velocity of 58 feet per second at 85` F. The Department is of the opinion that the plans, specifications, and the Standard Operating and Maintenance Procedures pertinent to the submittal are in conformance with current air pollution control engineering practice, and hereby grants CONDITIONAL APPROVAL for the described installation,. as submitted, with the following provisos: 1. That the final plans, specifications and Standard Operating and Maintenance Procedures shall be submitted to the Department for written FINAL APPROVAL prior to the operation of the subject odor control system. 2. That should any nuisance condition(s) be generated by the operation of this facility, then appropriate steps will immediately be taken by the South Essex Sewerage District to abate the nuisance condition(s). 3. That the ability of the equipment to maintain emission rates at or below the stated levels must be demonstrated when and if, in the opinion of the Department, such should prove necessary. 4. That the second stage scrubbers on each of the tandem scrubber system trains shall be designed and operated to allow for the pH control of the sodium hypochlorite scrubber liquor at a minimum pH of 8. An Environmental Notification Form (EOEA NO. 7059) was submitted by the proponent as required by the Executive Office of Environmental. Affairs under the General Law Chapter 30, Section 62, and was subsequently signed by the Secretary on July 11, 1988. Please be advised that this approval does not negate the responsibility of the South Essex Sewerage District to comply with this or any other applicable federal, state, or local regulations in the future_.

Re: SALEM -Metropolitan Boston/ Northeast Region 310 CMR 7.02 -Plans Approval Appl. No. MBR -87 -IND -176 FINAL APPROVAL The Metropolitan Boston/Northeast Region of the Department of Environmental Quality Engineering, in reply to the request contained in a letter from Woodman Engineering, Inc., dated October 29,1987, and as modified on August 24, 1988, has reviewed the plans, specifications and the Standard Operating and Maintenance Procedures relative to the proposed modifications at your tanners' oil manufacturing facility located at 60 Grove Street in Salem, Massachusetts. The submitted information bears the seal and signature of Mr. David Woodman, Massachusetts registered Professional Engineer Number 26954. This review of the submitted information by Department engineers discloses that your firm proposes to modify your existing wastewater treatment facility. This modification involves the installation of two fiberglass oil/water separation tanks, the installation of one wet scrubber system, and the reuse of an existing separation tank as a "clean" water holding tank. The two new separation tanks have maximum holding capacities of 14,000 and 16,000 gallons. These tanks, which will be alternately employed to process wastewater, are each equipped with acid and caustic inlet lines, compressed air spargers, and a manually operated tube type oil skimmer. The wastewater generated by the manufacturing processes at the subject facility will be piped into one of the two separation tanks. When the first tank becomes full, wastewater generated by the manufacturing processes will be diverted to the alternate tank. Meanwhile, the full tank's contents will be pretreated prior to its discharge into Salem Oil and Grease Co. page 2 September 16, 1988 the public sewer system. This acidic wastewater is adjusted to a nominal pH of 2 while being mixed for a minimum of 15 minutes by agitation created by the compressed air spargers. After agitation, the wastewater is allowed to separate for approximately 4 hours. Following the separation period, the oil fraction will be manually skimmed from the top of the separation tank with the oil skimmer. The recovered oil will be accumulated in the existing recovered oil tank until the tank is filled. The recovered oil will then be recycled back into the manufacturing process. The skimmed wastewater on the other hand, will be transferred to the "clean" water holding tank where it will gradually be fed into a neutralization tank prior to its discharge to the South Essex Sewerage system. All the wastewater treatment tanks as well as the recovered oil tank are covered and will be ventilated. The headspace ventilation gases will contain sulfuric acid mists generated during normal wastewater treatment processing. These acidic exhaust gases will be controlled by a Viron International Model Number VSS-2424-FRP-2-60- S-1-D-460-3-60 counterflow packed bed scrubber and mist eliminator assembly having a maximum rated air handling capacity of 2000 standard cubic feet per minute ( SCFM). This scrubber will employ 20 cubic feet of Munters "PLASdek" size No. 12060 fluted PVC packing material having a superficial surface area of 68 square feet per cubic foot. The scrubber is rated at an overall sulfuric acid mist removal efficiency of 95 percent. The scrubber exhaust will be discharged through a PVC stack, the top of which will be 36 feet above ground level. This stack will have an inside exit diameter of 14 inches which will provide a flue gas exit velocity of 28 feet per second while handling 1800 SUM of exhaust. On November 12, 1987, the Department granted a CONDITIONAL APPROVAL for the subject installations. The Department is of the opinion that the plans, specifications and the Standard Operating Procedures for the proposed scrubber system are in conformance with current air pollution control engineering practice and hereby grants a FINAL APPROVAL for the subject installations with the following provisions: 1. That should any nuisance condition(s) be generated by the operation of this facility, then appropriate steps will immediately be taken by Salem Oil and Grease Co. to abate the nuisance conditions(s). 2. That a daily log of all maintenance actions performed on the scrubber shall be maintained on site for a minimum of two years; and that said log shall be made available to Department personnel upon request. Salem Oil and Grease Co. page 3 September 16, 1988 3. That all treatment tanks' access hatches shall be kept closed at all times when not in active use. Failure to comply with any of the above stated provisions will constitute a violation of the "Regulations", and can result in the revocation of the approval granted herein to operate the described facility. An Environmental Notification Form, for Air Quality Control purposes, was not required for this action since it is categorically exempt pursuant to the Regulations Governing the Preparation of Environmental Impact Reports adopted by the Secretary of Environmental Affairs. Please be advised that this FINAL APPROVAL does not negate the responsibilty of the Salem Oil and Grease Co. to comply with this or any other applicable federal, state, or local regulations now or in the future.
