Air Monitors Detect Benzene at Fenceline of Shell Cracker in Monaca
Air monitors at Shell’s ethane cracker plant detected elevated levels of benzene (which can cause cancer in humans) following an April 11 malfunction. However, an industrial hygienist told attendees at Tuesday night’s webinar session with local residents that the levels of benzene detected at the cracker’s community-adjacent fenceline during and after the release were too low to cause “even transient discomfort or irritation.” The highest concentrations found outside the fenceline were “in the parts per billion range.”

Last night, Shell hosted a virtual community meeting to address air monitoring and recent problems experienced at the company’s ethane cracker plant in Beaver County, PA. Executives answered questions about the plant’s environmental record over the past six months, including a recent odor event earlier this month (see 
The mighty Shell ethane cracker has had “issues” getting and staying fully up to speed. Since it officially went online last November, Shell had received three separate notices of violation (NOVs) for exceeding allowable air pollution limits, largely related to repeated flaring episodes, as of the end of March (
The mighty Shell ethane cracker seems to have “issues” in getting and staying fully up to speed. We’ve previously reported on a series of emergency flaring episodes at the plant (see 
New shale permits issued for Feb. 20-26 in the Marcellus/Utica slide lower last week. There were 29 new permits issued in total last week (down from 35 the week before), including 24 new permits for Pennsylvania, no new permits for Ohio, and five new permits issued in West Virginia. Last week the top receiver of new permits by far was the largest natural gas driller in the country, EQT Corporation, with 20 new permits split between Greene and Washington counties in southwestern PA.
The Pennsylvania Dept. of Environmental Protection (DEP) issued a Notice of Violation (NOV) early last week to the Shell ethane cracker plant in Monaca (Beaver County), PA, now called the Shell Polymers Monaca facility, for the third time since it officially began operation last November. In a letter dated Feb. 13 (copy below), the DEP stated the facility violated rolling 12-month emission standards in both November and December. Shell faces fines of $25,000 per day for each day the facility exceeds emissions limits. In light of this most recent NOV, two anti-fossil energy groups have asked the DEP to immediately shut down the facility to stop extra air pollution in the region.
It hasn’t been a problem-free startup for the mighty Shell ethane cracker plant in Monaca (Beaver County), PA, now called the Shell Polymers Monaca facility. We’ve noted some of the more prominent issues as we’ve spotted them in the news. Things like the plant exceeding allowed air emissions (see 
Yesterday two radicalized Big Green groups–the Environmental Integrity Project (based in D.C.) and the Clean Air Council (based in Philadelphia)–filed a notice of intent to sue the Shell Polymers Monaca ethane cracker plant near Pittsburgh. The notice, as well as the coming lawsuit, has all the hallmarks of being planned long ago, perhaps years ago, before the cracker plant even came online. The false claim in the notice and coming lawsuit is that the cracker plant is “repeatedly” violating air pollution limits.

Yesterday the Pennsylvania Dept. of Environmental Protection (DEP) issued a notice of violation (NOV) to Shell Chemicals Appalachia, LLC (Shell) for exceeding its rolling 12-month total emission limits of volatile organic compounds (VOCs), which happened during the commissioning of its cracker plant facility in Beaver County. Shell is limited by state permits to 516.2 tons of total emissions of VOCs over a rolling 12-month period. It had 521.6 tons by the end of September and 662.9 tons of VOCs by the end of October. The emissions are associated with the initial startup of the facility and (hopefully) won’t happen again.
