EPA Fines California Portland Company (CPC)

California Portland Company (CPC) is the largest producer of sand, gravel and quarry rock in the Pacific Northwest. CPC owns and operates three Portland cement plants in the United States and is headquartered in Glendora, Calif.
The facility covered by the settlement is located in Kern County, Calif. The Facility includes a dry process Portland cement manufacturing facility with an annual capacity of 1.44 million tons of cement clinker, along with a nearby quarry to mine raw products such as limestone and clay for use in cement production. 
Emissions from the Mojave plant are approximately 3,200 tons of nitrogen oxides (NO_x) and 1,200 tons of sulfur dioxides (SO₂) per year.
The consent decree requires CPC to install and continuously operate BACT-level emissions controls to reduce emissions of NO_x and SO₂.

• NO Emission Limitations and Controls_x

The settlement requires the installation and continuous operation of a selective non-catalytic reduction (SNCR) unit to control NO_x emissions.  While the plant is required to conduct testing in order to set a final NO_x limit after the CD is entered, CPC is required to meet a final 30-day rolling average emissions rate of no greater than 2.5 lb of NO_x per ton of clinker produced.

• (SO) Emission Limitations and Controls₂

The settlement will require the installation and continuous operation of a lime injection system (LIS).  While the plant is required to conduct testing in order to set a final (SO₂) limit after the Decree is entered, CPC is required to meet a 30-day rolling average emission rate of no greater than 1.7 lb (SO₂) per ton of clinker produced.

• NO emissions are expected to be reduced by more than 1,200 tons per year_x
• (SO₂) emissions are expected to be reduced by more than 360 tons per year

 NO_x and (SO₂) have adverse effects on human health and the environment as discussed below:

• Nitrogen Oxides-- NO can cause or contribute to a variety of health problems and adverse environmental impacts, such as ground-level ozone, acid rain, global warming, water quality deterioration, and visual impairment.  Affected populations include children, people with lung diseases such as asthma, and exposure to these conditions can cause damage to lung tissue for people who work or exercise outside._x
• Sulfur Dioxide -- High concentrations of (SO₂) can affect breathing and may aggravate existing respiratory and cardiovascular disease.  Sensitive populations include asthmatics, individuals with bronchitis or emphysema, children, and the elderly.  (SO₂) is also a primary contributor to acid deposition, or acid rain.

CPC will pay a total penalty of $1.4 million to the United States for violations resolved in the Decree.

EPA Classifieds Trichloroethylene as a Human Carcinogen

The U.S. Environmental Protection Agency (EPA or Agency) just released its Toxicological Review of Trichloroethylene (EPA/635/R-09/011F, September 28, 2011) (Toxicological Review). This publication represents the first time that EPA has classified trichloroethylene (TCE) (CASRN 79-01-6) as a human carcinogen regardless of the route of exposure. TCE had previously been classified as a "possible human carcinogen."

     

According to the Agency, the purpose of the Toxicological Review is to provide scientific support and rationale for the hazard and dose-response assessments given in its Integrated Risk Information System (IRIS) pertaining to chronic exposure to TCE. TCE is a volatile chemical widely used by industry as a chlorinated solvent; and unfortunately, it is also widely found at contaminated sites, including hundreds of Superfund facilities across the country.

The Toxicological Review concludes that based on the available human epidemiologic data and experimental and mechanistic studies, "TCE poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing fetus. The evidence is more limited for TCE toxicity to the respiratory tract and female reproductive system."

The chief impact of this new hazard classification will likely be on the developing vapor intrusion standards and on groundwater remediation projects.

Judge Cancels Order Prohibiting Use of SCAQMD Emission Credits

A Los Angeles Superior Court judge has revoked her 2008 order prohibiting the South Coast Air Quality Management District (AQMD) from granting emission offsets to essential public facilities including police, fire, wastewater treatment and landfills, as well as exempt sources such as business with low emissions.

"This action will ensure that in the future essential public facilities can expand to accommodate population growth and businesses can grow to support the region's economy," said Barry Wallerstein, AQMD's executive officer. "It will also help ensure our continuing progress toward clean air for all Southland residents."

Judge Ann I. Jones this month granted a motion by AQMD to revoke her previous order prohibiting AQMD from providing its emission offsets to essential public services and exempt sources such as low-emitting businesses. In her order Jones rejected arguments by environmental groups that claimed AQMD did not adequately address issues raised in her original decision.

Federal Court Sentences Southland Businesman for Asbestos Violations

On June 6th a federal court judge sentenced a Southland businessman to a four-year prison term for violating asbestos removal and disposal laws during the renovation of a large San Fernando Valley apartment complex.

U.S. District Court Judge Percy Anderson sentenced Charles Yi to 48 months in prison. Yi was convicted on March 29 by a federal district court jury in Los Angeles of five felony counts of asbestos violations. The sentence is one of the longest handed down by a Los Angeles federal court judge for asbestos violations.

"Exposure to asbestos poses a very serious health risk to workers and nearby residents alike," said Barry Wallerstein, Air Quality Management District's (AQMD) executive officer. "We hope these criminal sentences will deter contractors from violating asbestos air quality regulations."

The five counts against Yi include conspiracy to violate the Clean Air Act, failing to provide proper notification to the U.S. Environmental Protection Agency and AQMD about a renovation involving asbestos-containing materials, failing to provide properly trained personnel, failing to properly remove asbestos and failing to properly dispose of asbestos waste.

Judge Anderson on June 6 also sentenced John Bostick, who cooperated in the investigation, to a sentence of 6 months home confinement and 150 hours of community service. Bostick had previously pleaded guilty to conspiracy to violate the federal Clean Air Act.

In 2006, AQMD received complaints of possible improper removal of asbestos-containing materials during the renovation of a 204-unit apartment complex in Winnetka. Following inspection, AQMD inspectors found that asbestos was present in the ceilings of apartments in the complex and that untrained, non-certified workers were hired to scrape the asbestos-containing material from the ceilings. The improper asbestos removal caused asbestos fibers to spread throughout the apartment building and surrounding area, endangering public health. AQMD immediately shut down the renovation.

AQMD rules, which implement portions of the federal Clean Air Act, require that an asbestos survey be conducted by a certified asbestos abatement contractor before a renovation project can begin. If asbestos-containing materials are identified, the responsible party must submit to AQMD for approval a plan on how the material will be properly handled, removed and disposed of before renovation activities commence.

The case brought against Yi and Bostick was jointly conducted by the AQMD, U.S. EPA, the California Department of Toxic Substances Control and the U.S. Attorney's Office.
