We worry a lot about terrorists. Yet we barely ever give a thought to the guys testing samples at our municipal water plant or
operating the pollution controls at the power plant a few towns away -- unknown persons, laboring in obscurity, who can seriously hurt us through negligence and
malfeasance.
The real daily risks we face are more familiar, more ordinary,
and closer than we think.On June 9, U.S. District Court Judge Mark G. Mastroianni sentenced Scott Paterson, age 46, of Manchester, CT, to one year of probation for tampering with environmental monitors while working as an instrument and control technician at the Berkshire Power Plant in Agawam, not far from Springfield.
The Office of Acting U.S. Attorney William D. Weinreb of
Massachusetts reported that:
- From 2008 to March, 20111, Paterson, at the
direction of senior managers at the plant, tampered with the plant’s Continuous
Emissions Monitoring System (CEMS), which measures and records concentrations of regulated pollutants emitted at Berkshire.
- The purpose of the tampering was to delay
repairs and avoid reporting to federal and state regulators that the plant was,
at times, releasing certain pollutants, specifically nitrogen oxides, in excess
of the plant’s Clean Air Act permit limits.
- Initially, the tampering involved lowering
monitors by a constant rate – approximately .5 parts per million (ppm) – below the
known value. These constant adjustments
did not trigger any alarms or warnings and were thus usually maintained in the
system through approximately Mid-March of 2011.
- In the summer of 2009 and 2010, the plant
underwent an independent annual audit.
Prior to the audit, Paterson’s supervisor directed him to take out the
adjustments in the CEMS monitors and then to reinstate them after the audit.
- By 2010, this .5 ppm adjustment was not sufficient to allow the plant to run at full power and to comply with the facility’s Clean Air Act permit. Rather than making necessary repairs, Paterson, again at the direction of his supervisors, lowered the CEMS readings even more to avoid (a) reporting emissions in excess of the hourly limits or (b) hitting warning levels.
In March, 2017, Berkshire Power Company and Power Plant Management Services, the owners and operators, respectively, of the plant, were ordered to pay $7.25 million in fines, penalties and other payments for their roles in tampering.
