US EPA Proposes to Authorize Arizona’s Hazardous Waste Management Program Revisions

Between May 26, 1998, and July 28, 2006, the United States Environmental Protection Agency (EPA) revised certain rules under the Resource Conservation and Recovery Act (RCRA). To maintain equivalency of state and federal programs after these changes, Arizona has applied to EPA for authorization of changes to its hazardous waste program under the RCRA.

EPA has reviewed Arizona’s application with regards to federal requirements and is proposing to authorize the state’s changes. EPA’s proposed determination is subject to public review and comment.

ADEQ fish advisory for Largemouth Bass

PHOENIX – The Arizona Department of Environmental Quality, in association with the Arizona Game and Fish Department (AGFD), has issued a fish consumption advisory for largemouth bass caught from Willow Springs Lake in Coconino County that recommends healthy consumption amounts. This advisory is based on recent analysis of Willow Springs Lake largemouth bass fish tissue sample data that showed elevated levels of mercury.

ADEQ recommends that adults limit consumption of largemouth bass to 2.5 ounces (uncooked weight) per week and children 12 years of age and younger limit consumption to two ounces per month (uncooked weight).

Willow Springs Lake is home to a variety of fish and during the spring and summer, the AGFD stocks the lake with rainbow trout that can be eaten in unlimited amounts.

Fishing, bird watching, swimming and other recreational activities at Willow Springs Lake are not affected by this advisory and are encouraged for enjoying the great outdoors. Generally, any contaminant levels found in water are several folds lower than in fish tissue.

Fish are an excellent source of protein and can be an important part of a healthy, diverse diet as they are low in saturated fat. The American Heart Association recommends people eat at least two fish or seafood meals every week. The public health recommendations in this advisory are based on frequent and long-term consumption of fish, not infrequent or occasional fish meals.

Passage of Voluntary Emissions Bank HB 2152 Creates Incentives for Arizona’s Business Economy and Improved Air Quality

PHOENIX – Arizona Department of Environmental Quality officials today thank Governor Ducey for signing House Bill 2152, Emissions credits; voluntary emissions bank, into law, which provides both new and expanding Arizona businesses added opportunity in meeting mandatory federal Clean Air Act requirements to improve air quality, and may serve as a draw for new industries to locate to our state.

Prior to the passing of HB 2152, surplus emissions reductions deposits to Arizona’s emissions bank, which can be purchased by new or expanding businesses to meet Clean Air Act permitting requirements, were accepted only from permitted industrial facilities (traditional sources). Surplus emissions reductions are generated when a company reduces its air emissions below legal limits.

Representative Russell Bowers, R-25, sponsor of the bill, said, “With the demands of the EPA pressing upon our unique desert environment and its ambient production of ozone constituents, we have not been able to find permit space for new industry needs for air permits. While I have concerns about intruding into mobile sources, this voluntary approach could prove a great benefit to industry growth in Arizona.”

Enactment of this legislation expands the emissions bank to accept deposits from “non-traditional sources,” such as reductions generated through electrification of vehicle fleets. Allowing deposits from non-traditional sources will significantly increase the number of credits that could be deposited. For example, Maricopa County reports that 86 percent of contaminants that contribute to ozone generation come from non-traditional sources, mostly vehicles. This bill provides both an economic and environmental opportunity because it supports business growth in Arizona and incentivizes further air emissions reductions through a voluntary free-market sale process.

ADEQ Air Quality Division Director, Timothy S. Franquist, said, “The enactment of HB 2152 is consistent with Governor Ducey’s vision for agencies to be actively looking for ways to increase economic growth in Arizona. The enhanced voluntary Arizona emissions bank achieves both economic and environmental benefits by allowing new types of emissions offset credits to be used.” Franquist further explained that, “Arizona’s model is not a ‘cap and trade’ regulatory structure used elsewhere in the country.”

“These changes are a win-win for business and air quality,” Maricopa County Board of Supervisors Chairman, Denny Barney, District 1, said. “The emissions bank allows the County to keep and attract desirable high-tech companies while working toward achieving air quality standards.”

ADEQ and Maricopa County officials worked cooperatively with stakeholders throughout the legislative session to develop and refine key provisions of the bill as follows:

  • Clarifies that the State does not receive any new authority to establish emissions limits for stationary or mobile sources, participation in the emissions bank is voluntary and credits do not expire
  • Prohibits banked credit sweeps by ADEQ or any other entity
  • Allows non-traditional credits to be banked

Struggling Small Water Systems Get Financial Boost from House Bill 2094

PHOENIX – Arizona Department of Environmental Quality officials thank Governor Ducey today for signing House Bill 2094 into law, which expands grant eligibility to help small public water systems in need of water quality upgrades and infrastructure repairs. Sponsored by Representative Russell Bowers, R-25, HB 2094 makes the small water systems fund available to assist many of the 60 small water systems currently delivering water with contaminant levels exceeding federal safe drinking water standards.

Representative Bowers said today, “Unlike many state and federal environmental agencies, I am grateful to see our ADEQ become a proactive force for resolving problems, rather than heavy-handed enforcement. Providing this relief for many of our small water folks is very satisfying.”

In partnership with the Arizona Corporation Commission and the Water Infrastructure Finance Authority, ADEQ now has authority to provide grants for small water companies to maintain healthy and reliable water for their customers.

ADEQ Water Quality Division Director Trevor Baggiore said, “ADEQ’s goal is to ensure that every water system in Arizona delivers healthy drinking water to its community. These changes to HB 2094 are an important step in meeting that goal and we look forward to putting them to effective use with the ACC and WIFA.”

Significant benefits of HB 2094 include:

  • Expands eligibility for small systems, serving 10,000 or fewer people (previously limited to 500 or fewer connections), which often are the sole water provider in a rural area and lack the customer base and revenue required for costly upgrades.
  • Allows grants to be issued directly to owners (previously only interim operators or managers), like small municipalities and some rural schools, to fund necessary infrastructure upgrades to comply with safe drinking water standards.
  • Protects the interests of Arizona’s smaller, rural communities and the State through its structure, which requires consultation between ADEQ and ACC in recommending systems to receive grant funding. In addition, ADEQ’s Director must demonstrate and certify the direct public benefit of each grant.

HB 2094 further allows ADEQ’s Director, in consultation with the ACC, to swiftly address water emergencies when necessary, outside the state procurement code.

“We have an infrastructure crisis in Arizona, especially in rural areas,” said ACC Commissioner Andy Tobin, who has been a champion in addressing water service emergencies and chairs the Commission’s Water Committee. “The customers can’t wait for long-term solutions to water problems. The signing of HB2094 is the next step in solving these problems and lets us, along with ADEQ and WIFA, act immediately.”

“Managing this program for the state allows WIFA to help even more water systems with important water projects to protect the environment and safeguard the well-being of Arizona families,” said WIFA Executive Director, Trish Incognito.
