• City owned and operated municipal landfill 1930s until 1971 • 255 acres in northwest quadrant of the City • Less than 16 acres now remain NYSDEC IHWDS (Class 3) • “Legacy Site” Consent Order with NYSDEC • 1655 Lexington Avenue parcel delisting investigation and subdivision
Petition burden under 6NYCRR Part 375-2.7(e): Demonstrate that consequential amounts of hazardous waste disposal did not occur
Port Redevelopment Planning Began in 2006 - Repurposing of Port of Rochester fast ferry terminal, facilities, and grounds - Extensive pre- planning required due to project location and site history - Excavation and construction of 4.7 acre marina basin
• Excavation of 4.7 acre marina • Extension of River Street • Rerouting of Major Sanitary Sewer • Reconfigure Water, Telephone, Electric, Street Lighting, Fiber optics, Gas • Relocation of iron slag and other materials (3 spoil material classifications) • Monitoring tracking of excavated soils and fills • Dewatering of marina basin
• Former Iron Foundry Late 1800s to mid 1920s • Rail yard, blast furnaces remnants remained in subsurface. • Foundry waste products (e.g. sand, slag, and C&D) were spread eastward into low areas toward Genesee River. • Marina excavation required removal of 100,000 cubic yards of iron slag fills • Not cost effective to dispose of slag at 6NYCRR Part 360 Landfill • Beneficial reuse of slag used to support solar array project at FESL and Inner Loop
• Slag considered a regulated solid waste under 6NYCRR Part 360 regulation • City of Rochester reached and agreement with the NYSDEC / Beneficial Use Determination to reuse slag at FESL • Excavated and relocated 100,000 cubic yards of slag to FESL • BUD: process to DOT Type 2 subbase or use directly as embankment in place • Over 11,000 truck loads of slag relocated to FESL to construct for solar array project
• Overall Goals: - Reuse of vacant delisted portions of FESL (1974) - Renewable energy generation - Energy cost savings to the City • USEPA’s RE -Powering America’s Land Initiative • Renova/Brightfield Solar PPA Feasibility Study 2013 • NYSERDA NY Sun Incentive Program: 2 MW solar array • PPA Request for proposal (May 2015) • Solar developer selection process - July – December 2015 - Nine proposals submitted
• PPA executed with Solar Liberty (March 2015) • 25 year lease to Solar Liberty • Solar Liberty designs, constructs, maintains and operates system • City agrees to purchase power at lower rate • Remote net metering benefit for City • RG&E credits exceed PPA costs • Status: - Financing, incentive program and interconnection approvals in place - City building permits issues - April 2017 construction start
• Compliance with FESL consent order requirements • State Superfund delisting of 13 acres for solar development site • Beneficial reuse of 100,000 cubic yards of iron slag material to construct solar pad • $4 million slag disposal cost avoidance for marina construction project • State of the art Port of Rochester Marina (completed in Spring 2016) • City – Solar Liberty PPA will result in: -Annual electricity cost savings of about $90,000 for 25 years -Greenhouse gas emissions reductions in support of the City’s Climate Action Plan (~2,170 metric tons CO 2 equivalent/yr) -Renewable energy generation on land vacant for over 40 years

1. What are the basic requirements that must be established in order to successfully “delist” a parcel from the NYS Inactive Hazardous Waste Disposal Site Registry? 2. Why was it necessary to establish a Beneficial Use Determination for the use of the iron slag? 3. What is the City of Rochester’s primary obligation under the solar power purchase agreement, and why is this a benefit to the City?
