The third draft of the pFEIS was provided as a result of comments from the Village of Rye Brook (Village) Board and consultants in February 2020 on the January 2020 pFEIS. We have confirmed that prior HDR comments regarding information and analyses to be included in the pFEIS have been addressed, with the exception of mitigation for the potential increases in noise levels at the Arbor condos and at the Village Hall, Police Department and Fire Department, as discussed in this memo and previous memos. Permit approval conditions for the Village’s consideration at a later time during Village permitting required prior to mobilization for demolition / construction activities, are also provided below. If applicable, these recommendations could also be used for the Village’s pFEIS findings statement. Noise Arbors As per prior comments over the course of reviewing the project, HDR recommends that prior to the start of construction and demolition activities the Village consider requiring the applicant to install a 12 foot tall noise barrier along the entire perimeter of the Project Site on the western property line for the purpose of P a g e | 2 shielding the Arbors Condos, in addition to the barrier along the southern property boundary already committed to in the pFEIS.. • Significantly elevated noise levels are anticipated at the Arbors condos during construction for up to 17 months. o Per the pFEIS, increases in noise levels up to 12 dBA are anticipated at the Arbors condos (North Side of Ivy Hill Crescent) during portions of the approximately 6 months of site demolition and ground clearing. o In addition, these same residents would also experience a noise level increase of up to 9 dBA intermittently over the course of another 11 months during the construction period. o These noise increases would be perceived by residents using their outdoor space as a doubling of noise. o Although the pFEIS claims that interior noise levels during construction would be expected to be 45 dBA, which is considered acceptable, any outdoor use would be disrupted by this noise increase which could be perceived as a doubling of noise. o The applicant claims in the July 2, 2020 pFEIS submission memo that the assumed simultaneous demolition and ground clearing activities is not likely to occur. However:  The applicant does not commit to not performing these activities simultaneously; and  Other construction activities are predicted to increase noise levels by up to 9 dBA intermittently over the course of another 11 months during the construction period. Village Hall, Police Department and Fire Department As per prior comments over the course of reviewing the project, HDR recommends that prior to the start of construction and demolition activities the Village consider requiring the applicant to install a 12 foot tall noise barrier along the entire perimeter of the Project Site on the eastern property line for the purpose of shielding the Village Hall, Police Department, and Fire Department occupants, in addition to the barrier along the southern property boundary already committed to in the pFEIS.. • Per the pFEIS, increases in noise levels up to 11.8 dBA are anticipated at the property to the east (including Village Hall, Police Department and Fire Department). • In addition, interior nose levels would be approximately 57 dBA during the most noise-intensive periods of construction, which exceed the interior noise level limit of 45 dBA. P a g e | 3 • Noise walls could reduce noise levels for the benefit of the Village Hall, Police Department and Fire Department occupants. The Fire Department has been confirmed to include sleeping quarters that would be used during the day during construction hours. Recommendations for Permit/Approval Conditions Following the Village Board’s pFEIS findings, it is understood that specific Village approvals (e.g., Final Site Plan; Building Permits for demolition; etc.) will be required to specify conditions related to the future demolition and construction phases of the project. HDR recommendations (for future reference) are provided below for each of our main review categories. If applicable, these recommendations could also be used for the Village’s pFEIS findings statement. Air Quality • The following air quality control measures should be required as a permit/approval condition during demolition and construction activities. Many of these have been previously noted by HDR, during our technical reviews of the May 2019 pFEIS and the Draft Demolition Site Plan application (that was withdrawn). o Minimizing the area of soil that is disturbed at any one time; o Minimizing the amount of time during which soils are exposed; o Installing truck mats or anti-tracking pads at egress points to clean the trucks’ tires prior to leaving the Project Site; o Watering of exposed areas during dry periods without creating standing or flowing of water; o Covering stored materials with a tarp to reduce windborne dust; o Limiting on-Site construction vehicle speed to 5 miles per hour (mph); o Using truck covers/tarp rollers that fully cover hauled materials and keep debris and dust from being expelled from the truck along its haul route; o On-site visual monitoring of dust conditions to identify potential adverse air quality impacts from airborne dust and, potentially, the need implement a Community Air Monitoring Plan (CAMP); o Ultra-low sulfur diesel shall be utilized for all construction equipment and vehicles; o All equipment shall be properly maintained; o Idling of construction or delivery vehicles or other equipment shall not be allowed when the equipment is not in active use; o Trucks shall not be allowed to idle for longer than three minutes; o Cleaning the asphalt parking lot and driveway, including the construction entrance, and adjacent roadways (Arbor Drive and King Street) used for access to the site; and o Non-road diesel engines with a power rating of 50 horsepower (hp) or greater, and controlled truck fleets (i.e., truck fleets under long-term P a g e | 4 contract with the project) including but not limited to concrete mixing and pumping trucks, shall utilize Best Available Tailpipe (BAT) technology for reducing diesel particulate matter emissions. Diesel particulate filters (DPFs) have been identified as being the tailpipe technology currently proven to have the highest reduction capability. Contracts shall specify that all diesel non-road engines rated at 50 hp or greater shall utilize DPFs, either installed by the original equipment manufacturer or retrofitted. Retrofitted DPFs must be verified by EPA or the California Air Resources Board. Active DPFs or other technologies proven to achieve an equivalent reduction may also be used. Noise • The following noise control measures should be required as a permit/approval condition during demolition and construction activities. Many of these have been previously noted by HDR, during our technical reviews of the May 2019 pFEIS and Demolition Site Plan application. It is recommended that the Building Department request in-field noise level readings - if warranted based on site work activities - to confirm the noise levels are not above the applicant’s modeled criteria at property lines. o Erection of a noise barrier that is 12 feet tall along the perimeter of the Project Site on:  Arbor Drive along the southern property boundary, with the exception of the site entrance;  the western property boundary; and  the eastern property boundary. Details on the noise barriers to be constructed should be provided for review prior to mobilization. The noise barrier should be maintained throughout the demolition and construction activities. o Noisy equipment, such as cranes, concrete pumps, concrete trucks, and delivery trucks, shall be located away from, and shielded from, sensitive receptors, such as the school, to the extent practicable; o Equipment, including the mufflers on the equipment, shall be required to be properly maintained; o Electrification of construction equipment to the extent feasible and practicable shall be undertaken as soon in the construction process as logistics allow; o The site shall be configured to minimize back-up alarm noise to the extent feasible and practicable; o Trucks shall not be allowed to idle for longer than three minutes. o Generators shall be placed on the west side of the Project Site facing the Parkway, which shall avoid direct line of sight from the generators to the surrounding sensitive receptors, including The Arbors, Village Hall, and Village Hall Police and Fire Departments. Models with Level 1 or 2 sound enclosures shall be selected. P a g e | 5 o Equipment anticipated to increase noise levels at the property boundary by more than 6 dBA or to a noise level greater than 65 dBA shall include path controls. o Coordination with the School District. o The days of the week and time of day restrictions codified in the Village Noise Code, with the exception of the morning start time, as discussed in Section 2.16.2.2 of the DEIS, “Construction: Potential Traffic Impacts on the MS/HS”; Vibration • The permit/approval shall include a condition that a vibration monitoring program at The Arbors community and at the Tennessee Gas Pipeline (2 stations/ monitoring points) shall be implemented during demolition and during the use of construction impact devices (such as, jackhammers, pavement breakers, pile drivers, pneumatic tools, etc.) to ensure that vibration levels do not exceed the thresholds that could potentially result in damage to adjoining property, utilities (water, sewer, gas, electric, fiber / cable), etc. • Prior to starting demolition / construction (i.e., during Village permit stage), a site vibration monitoring plan should be prepared and should include a listing of a Tennessee Gas Pipeline contact, along with the contacts for all existing subsurface utilities at the site and adjacent properties (water, sewer, gas, electric, fiber / cable). It is recommended that the applicant make a notification to each utility entity (Tennessee Gas Pipeline and all others) prior to the start of demolition and construction activities, and report to the Building Department on such notifications and any feedback received. • Vibration monitoring shall be conducted in accordance with any demolition- related approvals from the Village. Outreach to contacts of the subsurface utilities on and around the project site shall be documented to the Building Department. Hazardous Materials • All interior building abatement (asbestos, lead-based paint; older electrical equipment such as light fixtures, switches, caulking that could contain mercury, PCBs, or other regulated materials), as required, should be completed prior to any demolition activities including but not limited to disturbing existing building walls and the existing slab. • It is recommended that the Village Building Department track progress on abatement activities conducted (asbestos containing material (ACM), lead-based paint, and other materials that may be encountered). • As agreed to (and as noted in the revised PFEIS), the Applicant shall prepare a Materials Management Plan (MMP) prior to the start of excavation or ground disturbance work. The MMP in accordance with the revised PFEIS shall be included as a permit/approval condition. Demolition shall occur in accordance with applicable regulations (OSHA, NYSDOL, etc.), and in accordance with any demolition-related approvals from the Village. P a g e | 6 • Copies of agency correspondences (NYSDOL, etc.) shall be submitted to the Building Department. • It is recommended that a list of transporters and potential recycling / disposal facilities that will accept demolition materials be provided to the Village Building Department prior to the start of work. It is further recommended that the applicant submit an inventory (demo materials / types, including abated materials; quantities removed; off-site destinations and disposal/recycling documentation) to the Building Department within 30 days of the completion of work. • Copies of all abatement filings (e.g., New York State Department of Labor for ACM) and memos describing abatement work completed shall be furnished to the Building Department within 45 days after completion.
