ITEM: NEW BUSINESS
Appl. #07-58P – Town of South Windsor – Vibert Road – Inland Wetland/Conservation Commission application for an expansion of the Water Treatment Control Plant and associated improvements on property located westerly of Main Street and southerly of Vibert Road. A-40 Residential Zone.
Fred Shaw, Superintendent of Pollution Control came before the Commission and presented the application for the upgrade of the town’s wastewater treatment facility. The following proposals were made:
· Upgrade the forty year old facility to allow it to handle the growth and devlopment of the Town for the next twenty to thirty years
· Improvements to the existing system to correct design deficiencies that date back to the early seventies
· Upgrading the plant to provide cost effectiveness in the operation of the facility
· Involves putting in new treatment systems which are required due to new regulation in the State for nitrogen removal. In order to meet the regulations the following items must be addressed
o A new airration basin installed
o A new system of handling waste water to be able to remove the nitrogen
o New secondary clarifiers must be put in
o New tanks and a new system for odor control
Shaw stated that the design of the project is nearing completion and every effort has been made to limit the disturbance to the wetlands, watercourses and 100 year flood plain. Shaw introduced William Langle, of Camp, Dresser & McKee as design consultant for the project. Shaw stated that it has been estimated that there will be a requirement for net fill of 109 cubic yards mostly along the eastern portions. Shaw stated that in order to compensate for the 109 cubic yards of fill, the design calls for a net cut of 109 cubic yards of material below the 100 year flood plain. There is a creation of 1/10 of an acre of wetlands to offset the proposed filling.
Shaw stated that there is an access road that is proposed to run around the site.
Chairperson Warren asked Folger if he was comfortable with the mitigation plan. Folger said yes and that the wetlandns that are proposed to be impacted are a forrested wetland and is on the fringe of a larger wetland area that occurs to the east and then wraps around to the south. Folger stated that a selection of woody and herbacious woodland plants and trees will be planted in the wetland area and the mitigation area is not only going to be excavated down to the 100 year flood elevation but down the elevation 28 which is comparable to the elevation of the existing adjacent wetland area.
Shaw handed out a proposed wetland specification to the Commission members.Langle stated that it is a typical CDM specificaton for wetlands. The specific plan for mitigation was submitted prior to the hearing.
Shaw stated that they are still waiting the DEP’s final review of the design plan and would like to begin the construction phase next year.
CityWarren state that the Commission should consider as part of the application the improvement to the placeConnecticut River because of the upgrade to the plant.
Kelly stated that there wasn’t really a separate created wetland. Folger stated that that was correct and stated that there is a profile on plan and it will be flat with some variations. Folger stated that a recommendation would be to have the soil scientist oversee the installation of it with a five year monitoring period for the plants. Folger stated that it would be rough graded down and then have the plants incorporated in.
Kelly asked if there would be fill on site or if it would be brought in. Langle stated that the net would be material leaving the site due to the volume of the new tanks that are being created so it would be a net removal.
placeCityWarren asked Folger for additional comments and he stated that he would ask as an approval condition that the perimeter erosion controls go around the edge of the mitigation area. Langle stated that there would be a revison shown to reflect that on the final plans. Additionally, there are trees of interest opn the site. Namely, some black walnut trees that will be cut down. The useable wood should remain town property to be used for projects.
placeCityWarren asked for public comment. Irene Pelletier of addressStreetMaskel Road came before the Commission and asked if the treatment plant treats all of placeSouth Windsor or certain areas. Shaw stated that it treats most of the town and portions of placeCityManchester.
