(O'Neill - Powers; all in favor) VOTED SOUTH MAIN ST. GROUNDWATER REMEDIATION: [CoMm. QLJI d'd nof�lU��c��tifC r`/ �/c cliScG Representative of Groundwater Technology appeared before the commission to describe work which needs to be done regarding pollution of groundwater from old Gorham Silver factory on South Main St. Cleansed water will be discharged into storm drain; before it is, it must meet primary and secondary drinking water standards. All work will take place on the project site itself (not at the houses). EPA application has been submitted; Groundwater Technology is present to notify the commission of a discharge of 3 -5 gallons per minute, with an eventual discharge to wetlands (about 1600 ft. away from the project site). Monthly testing will be required by EPA, commission will be copied. The project will run twenty -four hours per day, probably over several years. Chairman Cauldwell asked if any study had been made of the effects on groundwater in the area. Groundwater will be pumped out through three extraction wells. Two -stage particulate filtration, and two carbon filters. If any other sites were to be pumped, the commission would be notified. Commissioners asked the representative indicate that in writing. Comm. O'Neill suggested that lab tests be returned before pumping continues. It was noted that the entire cleanup and remedial process will be heavily conditioned and specified -by EPA and DEP. WETLANDS PROTECTION ACT HEARING - SE211 -407 Beverly Turner - -6 Riverwood Drive -- Proposed dwelling, septic, utilities within 100 feet of wetlands Mr. Trowbridge represented the applicant. Abutters have been notified. Proposal is for single family house, first lot on left as a part of the Riverwood Estates (only lot not owned by Harrington and Matto). Roof drains into drywell; lawn area limited to 7500 sq. ft. Wetland line was flagged in 189. Commissioners felt the wetland line had changed from the original subdivision plans, especially in the area behind proposed house and even in the proposed driveway. Comm. O'Neill asked for proposed limit of clearing to be on the plan. The commission will review the line at a site walk, with an appropriate wetlands expert, at 7:30 a.m. on October 31. MOTION: To continue the hearing to 11 -9-92 at 8:30. (O'Neill - Owens; all in favor) VOTED RESPONSE TO MR. CLEMMEY'S LETTER TO EDITOR (RE GREAT WOODS EXPANSION PROJECT) Dick has drafted letter responding to Mr. Clemmey's assertions ( which appeared in newspaper. Comm. Powers reiterated that all meetings, including hearings, are open to the public, and that all orders are determined in open meeting. Commissioners wished to note that orders incorporate discussion that has occurred at the public hearings as well as all information supplied by the applicants during MANSFIELD CONSERVATION COMMISSION MINUTES MONDAY, OCTOBER 26, 1992 -- PAGE 2 the hearing process. Comm. Powers pointed out that the town engineering dept. was consulted for review of relevant information, and were also present at some of the hearings. Finally, it was noted that an appeal process exists for any dissatisfied citizen. The appeal of an Order of Conditions should be directed not to the Board of Selectmen, but to the DEP. MOTION: To move that Chairman sign and send letter as revised. (Powers - Swith3 all in favor, O'Neill abst,) VOTER WETLANDS PROTECTION ACT HEARING CONTINUATION - SE211 -408 TGG Land Planning -- Plymouth St.-- Construct cul -de -sac at proposed terminus. of Plymouth St.; install culvert in Hodges Brook under proposed cul -de -sac Bruce Tyson presented the project, which is located at the end of Plymouth St, and involves the shortening of a cul -de -sac. The work proposed includes placing a culvert in Hodges Brook. Curbs and access points to future lots will be constructed. Proximity of wetlands was discussed at the previous hearing; the Commission concluded on the site that the wetlands line shown on the plan was a valid representation. The applicant will be displacing 410 feet of bank and will recreate bank condition by creating a bypass (island). The , project involves creation of a temporary dam, pumping water beyond the limit of excavation, creating energy dissipators and siltation devices. New areas will be stabilized. The project now must be . reviewed by the Army Corps and the Water Quality Certification Division, etc., so work will probably not begin until spring. Comm. Powers noted the relatively steep grade on the bank; she asked whether the replacement bank will be equally steep and whether that will present a problem with regard to the regs. regarding a 3:1 slope. It was felt there.is no problem with replicating the pre - existing condition, although the site will require a good temporary vegetative cover. Chairman Cauldwell asked the applicant about figuring out the 10 -year storm impact to see whether the commission has jurisdiction with regard to wildlife habitat. Alan Pilsbury, 155 Old Elm St., asked about runoff. According to the plans presented, the net impact of current project is less runoff, with no change to street drains. NOTION: To continue the hearing to 8:95 on 11 -9, with proposed set of orders to be ready if there are no additional comments from DEP, (O'Neill - Powers; all in favor, Smith ahst.) VOTED REQUEST FOR DETERMINATION OF APPLICABILITY TGG Land Planning, Inc.- -Lot 8000, Plymouth St. - -To establish wetlands boundaries at proposed site This project has been filed so the Commission can make a determination for that portion of the parcel which has not yet been reviewed with regard to wetlands boundaries. The plan highlights what has already been determined. Entire perimeter to be done is a little over a mile and surrounds a complex area. Mr. Pilsbury asked about the locus for this project, in relation to other projects in the area. MANSFIELD CONSERVATION COMMISSION MINUTES MONDAY, OCTOBER 2E, 1992 -- PAGE 3 Commission will walk the site on 11 -7 -92 at 7:30 a.m. MOTION: To continue hearing until 11 -9 -92 at 9:00 p.w.

VOTED WETLANDS PROTECTION ACT HEARING CONTINUATION - SE211 -404 Town of Mansfield -- Westerly side of Plymouth St.-- Install culvert in Hodges Brook; construct entrance road, clear land within wetlands buffer zone to create recreational facility Dick Lewis represented the town. The site walk resulted in a reevaluation of one area for possible use as a preferable replication area. Dick will be taking another look, to verify. Some areas have been re- flagged as a result of the site walk. Comm. Powers had some questions about the delineation at location E -W -H. Trowbridge will re- survey. For the next continuation, Dick proposed to locate the proposed driveway and parking lot on plan and to bringing forth final plans, reestablishing a 20 -30 ft. no- disturb zone. The project as proposed doesn't trigger any wildlife habitat regulations. Comm. O'Neill reminded the board of its responsibility under town charter to protect natural resources. Comm. Powers noted that Town meeting and the Board of, Selectmen have decided this land will be used for playing fields; the commission must work within those guidelines. The intent of the project is to clear large open space and not to leave areas of trees between fields. Comm. Owens noted his discomfort ("somewhat incensed ") about what was reported in the Mansfield News about supposed commission insensitivity regarding this project. He feels that selectmen should look at the project and suggested formally inviting selectmen to look at whole picture. Dick was asked to send a memo inviting the Board of Selectmen to join on the site walk on 11 -7 at 10:15. The town has submitted stepped plans for the culvert crossing, which should take a week at the maximum. Plan should show land under water body. Comm. Powers expressed reservations about changing the replication location and requested that it be reevaluated at the conclusion of a field walk on Plymouth St. on 11 -7. MOTION: To continue to ii -F at 9:30 p.m. with site walk on 11 -7 (t +'Nei11 - Powers; all in favor) VOTED REQUEST FOR DETERMINATION OF APPLICABILITY Wayne Carrigan - -52 King Arthur Way -- Construction of pool within 100 ft. of wetlands Wayne Carrigan appeared before the board. The proposed project is similar to one the commission has heard for this site; the previous hearing was for a barn /garage. The new plan shows a smaller building but a pool has been added.
