Of the chemicals reported, 1 is classified as carcinogen, representing 25% of the facility's chemical profile. The facility operates in the Electric Utilities sector. The primary release pathway is air releases, accounting for 100% of total releases. All release data shown below is self-reported to the EPA under the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313.
Where this facility sits in the TRI record
Among the 513 Electric Utilities facilities in this database, Manchester Street Llc. reports the 370th-largest volume (18.0K lbs). Its reported volume is concentrated rather than spread: Ammonia alone is 100% of the total.
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.
Manchester Street Llc. files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 221112 (Electric Utilities). Across 6 years of records spanning 2019–2024, the site has disclosed 18.0K lbs in cumulative toxic releases across 4 distinct chemicals, 1 of which (25%) carry a carcinogenic classification. Largest chemicals by pounds: Ammonia; Naphthalene; n-Hexane; 1,2,4-Trimethylbenzene.
The dominant release pathway is air releases at 21.8K lbs (100.0% of total volume). Between 2019 and 2024, reported totals increased by 226% - from 1.2K lbs to 3.8K lbs. The facility is operated under parent company Edgewater Generation L L C. Nearest other TRI reporters: Sprague Providence; Shell Providence Terminal; Mahr Inc.; Wt Terminal South. Similar-scale peers outside Rhode Island: Cumberland Energy Center; U.S. Tva John Sevier Combined Cycle Plant; Schiller Station; Indian River Generating Station.
TRI Form R values are self-reported estimates, not measured stack emissions, and treat every pound of reported chemical equally regardless of toxicity. Inclusion in the TRI database does not establish a health risk to nearby residents; it documents the annual reporting record that Manchester Street Llc. has filed with the EPA under federal community right-to-know requirements - open Sprague Providence for a different chemical mix before treating volume as risk.

About TRI Data
Data as of 2023 reporting year. Source: U.S. Environmental Protection Agency (EPA) Toxic Release Inventory.
Data comes from the EPA Toxic Release Inventory (TRI) program. Facilities that manufacture, process, or otherwise use listed toxic chemicals above threshold amounts are required to report annually to the EPA.
On this page the largest disclosed chemicals include Ammonia, Naphthalene, n-Hexane, 1,2,4-Trimethylbenzene; nearby reporters include Sprague Providence. "Total releases" includes air, water, land, and off-site transfers for disposal, aggregated across available reporting years. Quantities are self-reported estimates, not measured stack emissions.
PlainEnviro presents this data without advocacy framing. The presence of a facility in the TRI database does not by itself indicate a health risk. For site-specific health questions, consult your local environmental or health agency.
