Where this facility sits in the TRI record
According to the EPA Toxics Release Inventory, Nissequogue Cogen Partners filed Form R disclosures without reporting any release volume, one of 513 Electric Utilities facilities in this database. A zero total means nothing was reported under EPCRA Section 313, not that the site was assessed and found clean.
Placement is computed from reported TRI pounds in this database. Thresholds are fixed across every facility page: concentrated ≥60% of volume in one chemical, county-dominant ≥25% of the county total, carcinogen-heavy ≥50% of pounds. Share-based statements are shown only for sites reporting at least 1,000 lbs, because a share of a very small total is not a meaningful signal. Reported pounds are self-reported estimates and do not measure toxicity or health risk.
