  • The city's Las Vegas Street Water Resource Recovery Facility was the recipient of discharge that exceeded the limit for chromium, Utilities says.

Qualtek Manufacturing
has been hit by a finding that it exceeded limits on chromium discharged from the plant at 4230 N. Nevada Ave. into Colorado Springs Utilities wastewater stream.

While chromium is naturally occurring, ingesting high levels can lead to sickness.

Asked for a comment on the discharge, someone who answered the phone at Qualtek said, "No. I'm sorry."

Qualtek engages in tool and die, stamping and other metal works.

Utilities spokesman Steve Berry says via email no fine will be levied, because of three factors: 1) It was quickly remedied with no reoccurrence; 2) the monitoring plan was adjusted accordingly, and 3) the discharge containing the higher-than-allowed level was limited. In addition, he notes, "There were no operational impacts for our treatment plant."

The Qualtek detection came in November 2017 and registered at 1.24 milligrams per liter, or nearly twice the daily limit for chromium of 0.733 mg/L, according to Utilities.

The discharge went into Utilities' wastewater system, not a creek, Berry notes.

"Their wastewater is treated at the Las Vegas Street Water Resource Recovery Facility," he says. "This violation did not cause any treatment interference at the facility, and we did not have any permit violations or experience atypical chromium loadings. As this wastewater was in the Springs Utilities wastewater collection system, it did not impact any other users."

Berry says the period for which Qualtek was in "significant noncompliance" (SNC) was from Oct. 1, 2017, through March 31, 2018.

Says Berry:
The violation was discovered during a Springs Utilities monitoring event in November 2017, which put Qualtek into significant non-compliance for the SNC evaluation period of October 1, 2017 to March 31, 2018. Qualtek was required to begin completing monthly monitoring of chromium as a result of this violation (where they previously performed quarterly monitoring). All re-sampling completed by Qualtek and Springs Utilities since this event has demonstrated compliance. Additionally, Qualtek has evaluated their manufacturing processes as well as their preventative maintenance to determine the cause of the violation and has made appropriate modifications to prevent future occurrences.

The publication of such findings don't happen until the calendar year following a significant noncompliance event, he says.

The noncompliance "will be reported to the EPA in the 2018 Pretreatment Annual Report, which is due on March 28, 2019," Berry says.
