and disposal. Identify measures to avoid, minimize, or mitigate adverse effects from <br />the generation/storage of solid waste including source reduction and recycling. <br />Construction Generated Waste <br />Demolition debris and earth materials will be generated during demolition of the existing <br />residential structures. The solid wastes generated during demolition will be recycled or <br />disposed of at a state -permitted landfill. <br />Asbestos -containing materials (ACM) will require management prior to any demolition, <br />renovation, or operations and maintenance work that might disturb identified or assumed <br />asbestos materials. If ACM is discovered during renovation/demolition activities, disturbance <br />work will immediately stop until a determination regarding asbestos content within the <br />material is discovered. <br />Construction of the proposed development will generate construction -related waste <br />materials such as wood, packaging, excess materials, and other wastes, which will either be <br />recycled or disposed of in the proper facilities in accordance with state regulations and <br />guidelines. <br />Operationally Generated Waste <br />The proposed development would generate new demands on solid waste management and <br />sanitation services provided in the project site. Based on the proposed area of 215,290 <br />square feet, it is estimated that the residential waste stream will be around 2,321 tons per <br />year. Hazardous waste products are not anticipated to be produced or stored within the <br />proposed development. <br />c. Project Related Use/Storage of Hazardous Materials — Describe chemicals/hazardous <br />materials used/stored during construction and/or operation of the project including <br />method of storage. Indicate the number, location, and size of any new above or below <br />ground tanks to store petroleum or other materials. Indicate the number, location, size, <br />and age of existing tanks on the property that the project will use. Discuss potential <br />environmental effects from accidental spills or releases of hazardous materials. Identify <br />measures to avoid, minimize, or mitigate adverse effects from the use/storage of <br />chemicals/hazardous materials including source reduction and recycling. Include <br />development of a spill prevention plan. <br />One 265-gallon underground storage tank and one 300-gallon aboveground storage tank <br />were identified on -site during a 2022 survey. The underground storage tank is a heating oil <br />tank located to the northeast of the existing single-family homes. The aboveground storage <br />tank is a propane tank and is located to the northwest of the existing single-family homes. <br />Based on the age of the 265-gallon heating oil underground storage tank (50+ years) and <br />that it has been 24 years since the subsurface investigation was completed, there is an <br />inherent risk of release and leakage associated with the tank. The 2022 survey recommended <br />a Phase II Subsurface Investigation to assess potential impacts associated with the active <br />265-gallon tank. <br />Haviland Fields EAW 18 July 2023 <br />
