Special Sampling Projects - Republic Steel (Lead/Toxics)
Beginning June 6, 2017, Ohio EPA, through their partnership with Canton City Public Health, began special purpose sampling for lead and other toxics as required by Republic Steel’s December 2, 2016 permit issued as a part of operational changes at the facility. Republic Steel is a steel manufacturer located in Canton, Ohio (2633 8th St NE) who manufactures, among other steel products, leaded steel. The sampling takes place at monitors located across the street from the facility and in the community.
On April 29, 2019, Ohio EPA converted the designated primary lead monitor (monitor 39-151-0024) from a special purpose monitor (SPM) to a State or Local Air Monitoring Station (SLAMS). 40 CFR Part 58, Appendix D, Section 4.5(a) requires agencies to monitor for lead emissions around any facility that reports actual lead emissions of 0.50 tons per year or more. This requirement was triggered for Republic Steel based upon lead emissions of 0.81 tons per year reported under a revised 2017 emissions report submitted on January 18, 2019. U.S. EPA requires SLAMS monitors to collect lead samples at a frequency of 1 in 6 days and report those data to U.S. EPA’s Air Quality System (AQS). Monitor 39-151-0024 is used to fulfill this requirement. Conversion of the primary monitor to SLAMS retroactively converted previously collected SPM data to SLAMS data. Prior to April 29, 2019, the designated and alternate monitors collected data at a combined frequency of 1 in 3 days. After conversion to SLAMS on April 29, 2019, the designated SLAMS monitor began collecting lead samples at a frequency of 1 in 6 days, and the alternate monitor became dedicated to only the special studies described below.
In addition to the designated SLAMS monitor, Ohio EPA operates special studies monitors around Republic Steel. The special studies monitors are intended to supplement the SLAMS required monitoring in an effort to gain better knowledge about the lead and toxics emissions and the impact on the surrounding community. Ohio EPA is actively working with Republic Steel to address elevated concentrations of lead. The special studies monitors are not SLAMS monitors and data is not reported to U.S. EPA’s AQS. This website is dedicated to sharing all data from the special studies monitors and from the SLAMS monitor. Below you will find all data collected to date. As additional samples are collected, analyzed by the laboratory, and reported to Ohio EPA, new data will be posted here. Below is a map showing the location of the SLAMS monitor and the special studies monitors.
A violation of the National Ambient Air Quality Standards (NAAQS) for lead occurs when any rolling 3-month period exceeds 0.15 μg/m3. Only SLAMS monitors are used for comparison to the NAAQS.
