Fisher Engineering: how the 1.2K lbs splits

1.2K lbs across all reported pathways

  • Air Releases 1.2K lbs 100.0%

Fisher Engineering's 1.2K lbs Form-R total is AIR - air releases is 100.0% of the bar. Off-site transfers stay separate from air, water, and land releases. Leading chemical by pounds: Manganese compounds.

Carcinogen-classified pounds vs other reported pounds

Same cumulative TRI total as above, split by EPA/IARC carcinogen classification on each chemical: pounds share, not chemical count. Classification is not a site health-risk score.

Fisher Engineering is an EPA Toxics Release Inventory reporter in Rockland, ME, in the machinery sector. It reported 135 lbs of releases across 3 chemicals in 2024, and 1.1K lbs in total across its 2019-2024 reporting years. That ranks 13,752 of 25,986 TRI facilities nationwide by cumulative reported pounds, counting each facility over however many years it has filed. In Maine's 81 reporting TRI sites, Sappi N.a. Inc. - Somerset Operations leads both reported pounds (10.6M lbs) and chemical count (31 chemicals). The two rankings do not invert in this pool. Reported volume fell against 2022. Pounds reported are not a measure of toxicity or health risk. Nearest other TRI reporters: North End Composites; Dragon Products Co; International N&h USA Inc.; Pike Industries Inc-Washington. Similar-scale Machinery peers outside Maine: Nov Conroe Brandt/portable Power & R&d Rig Solutions Scot; Xylem Water Systems USA LLC; Electrolux Professional Group - Weidman; Nov Rig Systems Fm 529. Other Douglas Dynamics Holdings Inc sites in this extract: Henderson Products Inc. Largest disclosed chemicals by pounds: Manganese compounds; Chromium compounds (except for chromite ore mined in the Transvaal Region); Manganese And Manganese Compounds; Nickel compounds.

Fisher Engineering: Manganese compounds-led volume

Among the 1,186 Machinery facilities in this database, Fisher Engineering reports the 403rd-largest volume (1.1K lbs). Its reported volume is concentrated rather than spread: Manganese compounds alone is 76.1% of the total. Scale peers outside Maine include Nov Conroe Brandt/portable Power & R&d Rig Solutions Scot and Xylem Water Systems USA LLC.

Concentrated means ≥60% of Fisher Engineering's pounds in one chemical - here Manganese compounds at 76.1%. Not a toxicity score.
