The Washington State Department of Ecology (DOE) fined Alcoa Intalco Works $2,500 for violating several water quality regulations over the past six months.
DOE fined the Ferndale smelter for exceeding the maximum amount for daily fluoride discharge on October 15, 2020, according to the DOE, as well as monthly fluoride discharge limits for October and November 2020.
The smelter also didn’t meet sampling requirements for fluoride and suspended solids last October and surpassed the daily limit for oil and grease January 4.
The smelter has paid the $2,500 penalty, the DOE said. From January to March, the DOE issued over $82,000 in penalties that exceeded $1,000.
Alcoa announced curtailment of over 700 former Ferndale employees at the end of April 2020.
