Ms. Newman states that the previous Notice of Intent filing, for the Enforcement Order, has been proceeding and that the reason that they are not back before the Commission with a Certificate of Compliance is that the weather has been too hot and dry for planting trees and shrubbery. Ms. Newman states that the proposal before them tonight is for the madway construction. Ms. Newman adds that the proposal allows for 80% removal of total suspended solids via nmoff of this site. Ms. Newman states that the subdivision will be hooked up to City water and sewer. Chairman Lang asks if discussion could begin regarding stormwater management policy. 2 Curt Young of Wetlands Preservation Inc. addressed the Commission stating that the new Policy allows for nine standards to be met; one, is that no direct discharge to the wetland area shall occur; two, is that the proposals take care of the velocity flows not to increase to downstream neighbors; and three, is 80% removal of total suspended solids. Mr. Young stated that these are the major standards that are mentioned. Mr. Young states that the proposed detention basin will capture all water with a gravel bottom, and it will infiltrate out the bottom of the pond after rains to infiltrate the water. Mr. Young states that street sweeping in the winter time during construction activi'ties also assists in further mitigation as well as erosion controls. Chairman Lang asks what the two different types of stormwater systems that are being proposed. Mr. Young responds that the road runoff goes into a gravel bed detention basin while the other is in driveway vicinity which are drywells. Mr. Young states that the runoff from the roof also goes into these drywells. Mr. Lang asks how big are the drywells are for each house. Don Brings responds that they are 4' leaching type base, and that the State does not define drywell size, only that they to explain the drywell. Richard Benevento anives at the meeting (7:30 p.m.). Chairman Lang asks if the drywells are near the basement. Mr. Brings responds that he is unsure and that they can bring them away from the houses. Curt Young states that this proposal is for the roadway only, and that they will be filing for individual lots at a later time. Jay Donnetly asks what year storm this is designed for. Mr. Brings responds that it is designed for the 100 year storm. Mr. Dounelly asks why the plans indicate a discharge pipe that is crossed out on this plan. Mr. Brings responds that the State does not want to have this type of pipe. Debbie Hurlburr asks what the timetable is for the planting from the previous filing. Sally Newman responds that it is dependent on the weather, and when it rains more. Ms. Hurlburt asks if the roadway work is going to begin before the plantings are done. Ms. Newman responds that she does not think so. Tony Paluzzi asks what the timetable is for the building of the detention pond in relation to the other construction. Mr. Young responds that the detention pond can be built at any time. Don Brings states that the site need to be built up to grade, and the pond is built into a filled area. Pat Grimes asks who is responsible for the operation and maintenance of the detention pond. Mr. Young responds that eventually the City will be responsible, but adds that before the City accepts the street the developer is responsible. Ms. Grimes asks what is the time time for conslruction completion. Mr. Jones responds less than a year, perhaps 6-8 months.

New Public Hearing - 10-12 Congress Street / Morton International Mr. John Rendall from CH2M, a representative for Morton International introduces himself to the Commission and states that the proposed work for this site is a release abatement measure which calls for the excavation and offsite disposal of between 50-150 cubic yards of soils contaminated with mineral oil. Mr. Rendall states that a licensed site professional (LSP) will be providing private certification over the site for technical compliance, and that this site has full DEP oversite. Mr. Rendall adds that in June, DEP approved the site and the work.

Mr. Rendall states that the soil is behind the seawall. Mr. Rendall states that a public meeting was held in May to discuss this plan and there was a twenty day comment period. Mr. Rendall states that there will be 2-3 dump macks of mineral oil which is going to be used for asphalt recycling. Mr. Rendall adds that he will be putting up an aardvark oil boom when the work is done. Mr. Rendall states that because of tidal soils it is best to do this work in mid- August when the tide is at an extreme low at certain times of the day. Jon Mazuy asks how long the work will take. Mr. Rendall responds less than a week. Mr. Mazuy asks if the soils are wet will the material go into sealed trucks. Mr. Rendall responds yes. Pat Grimes asks if all the soils are going off site. Mr. Rendall responds yes. Richard Benevento asks if there is any other contamination.

Mr. Booris indicates that he has talked to several neighbors to stop this practice. Jon Mazuy asks if the entire area has been flagged. Ms. Rimmer responds that it has not. Mr. Rimmer adds that the soils are soft, indicative of wet areas. Mr. Mazuy suggests that the Commission take another look at the site and if there are other areas where dumping has occurred that the Commission move on those areas, and that perhaps a site visit on August 16 would seem appropriate. Joan Murphy of 36 Longmeadow Road states that there has been dumping occurring where there was historically wetlands, and that the area the parking lot is proposed is also an area that flooded historically. Ms. Murphy asks how long is the proposed conservation restriction for. Mr. Booris responds in perpetuity. Ms. Murphy states that there is 'some material that was placed there years ago from a gas station and that the material is contaminated.
