California requires replacement of all lead service lines – but vigilance needed on implementation

Tom Neltner, J.D.is Chemicals Policy Director

In 2016, California became the first state in the country to make enforceable commitments to eliminating all lead service lines (LSLs) in the state.  These lead pipes that connect the main under the street to homes are the primary source of lead in drinking water and unpredictably release lead particulate when disturbed.  Under the leadership of Senator Connie Leyva, the state’s Senate voted unanimously, and the Assembly voted 72 to 7 to pass SB1398 to require drinking water utilities to inventory LSLs in use and then provide the State Water Resources Control Board (Water Board) a timeline for replacement of the lines.

Based on a national survey of utilities, the American Water Works Association reported that California has 65,000 LSLs out of 6.1 million nationally.  Large utilities have the most with 46,000 LSLs, medium systems have 4,700 and small systems have 15,000.  However, most utilities do not have an accurate inventory of LSLs, so the true number may be much greater.

California’s SB1398 recognized that an accurate inventory was critical and laid out a thoughtful two-step plan to accomplish the objective of full LSL replacement.  By July 1, 2018, it requires public water systems (PWS) to submit an inventory of known LSLs and a timeline for their replacement.  Two years later, PWSs must submit an updated inventory of LSLs and provide a timeline to replace any service line where it may be made of lead.  The law does not set a deadline for replacement that PWSs must meet.

This two-step approach makes replacing known LSLs the highest priority and, by essentially presuming that a service line is lead unless known otherwise, also creates an incentive for PWSs to develop accurate inventories in the next three years.

Getting it up front: EPA clarifies substantiation requirements for CBI claims under the new TSCA

Richard Denison, Ph.D., is a Lead Senior Scientist.

The Environmental Protection Agency (EPA) is publishing a notice in tomorrow’s Federal Register affirming that the Lautenberg Act requires upfront substantiation of all confidential business information (CBI) claims submitted under the Toxic Substances Control Act (TSCA), except for certain claims that the law exempts from substantiation requirements.

While EPA initially took a narrower approach on an interim basis in the flurry of activity following last June’s passage of the Lautenberg Act, today’s notice supersedes that earlier approach and clarifies the upfront substantiation requirement.

In today’s notice, EPA notes the strong support for its clarification in the statute itself as well as in the legislative history in both Houses of Congress leading up to its final passage.

This clarification hopefully won’t be controversial:  A broad swath of stakeholders have voiced support for the upfront substantiation requirement and have noted that it is a key reform made by the new law.

In November the American Alliance for Innovation (AAI) sent a letter to EPA Administrator McCarthy signed by more than 60 trade associations – including the American Chemistry Council, the Society of Chemical Manufacturers and Affiliates, the American Cleaning Institute, the American Petroleum Institute and the Consumer Specialty Products Association – noting that under the Lautenberg Act “[c]laims for CBI protection must be accompanied by an upfront substantiation.”

And back in 2013, the American Chemistry Council provided responses to questions for the record posed by then-Congressman Henry Waxman that stated that “[i]mprovements to the CBI provisions in a modernized TSCA should include … [r]equiring upfront substantiation of the CBI claim.”  The same response letter noted that:  “The American Chemistry Council and its members support up-front substantiation of CBI claims.”

Importantly, EPA’s notice makes clear that the substantiation requirement applies to all non-exempt CBI claims made since passage of the law last June, although EPA is providing an exceedingly generous length of time for companies to comply.

Given the law’s 90-day deadline for EPA review of CBI claims, there are strong policy reasons for requiring upfront substantiation of CBI claims:

  • First, EPA’s own experience based on recent chemical reporting it has required demonstrates that requiring upfront substantiation reduces the number of CBI claims asserted. That means fewer claims EPA has to review and a greater likelihood that claims are only asserted for information that warrants protection.
  • Second, when those reviews are conducted, EPA will already have the information it needs to review the claim instead of having to request it from the company, wasting precious days or weeks of the 90-day review period.

On a roll: EPA proposes to ban or restrict two highly toxic paint stripping chemicals

Lindsay McCormick is a Project Manager.  

Yesterday, EPA proposed a rule to ban methylene chloride and either ban or restrict the use of N-methylpyrrolidone in paint stripping products, subject to certain national security exemptions. This proposal is the third such proposed action by the agency in the past month (see here and here). Below, find a short description of these chemicals and EPA’s proposed actions.

EPA achieves major TSCA implementation milestone

Richard Denison, Ph.D., is a Lead Senior Scientist.

The Environmental Defense Fund applauds the Environmental Protection Agency (EPA) for meeting a major milestone in implementing the Frank R. Lautenberg Chemical Safety for the 21st Century Act, the landmark legislation reforming the Toxic Substances Control Act (TSCA) that passed in June 2016 with overwhelming bipartisan support.

EPA reached this milestone this week when it released proposals for the three foundational rules that the Lautenberg Act mandates be finalized by June of this year, as well as three proposed rules restricting specific high-risk uses of several chemicals.

The management and staff of EPA’s Office of Chemical Safety and Pollution Prevention and Office of General Counsel deserve major kudos for their tireless work over these past seven months to reach this milestone. This should also bring satisfaction to the Members of Congress who authored the Lautenberg Act and included aggressive deadlines as part of the bipartisan effort to reform the law.   Read More »

With draft report, EPA takes major step to help communities assess risks from lead in drinking water

Tom Neltner, J.D.is Chemicals Policy Director

Communities around the country are testing their water for lead. But when they get the results, parents, public health officials, housing agencies and school officials have little guidance about what the number means and what actions to take or priorities to set. For lead in dust and soil in homes, child-care and schools, they have health-based numbers that serve as benchmarks for assessing risk. There is no such benchmark for drinking water. As a result, many are using the “Lead Action Level” of 15 parts per billion (ppb) as a surrogate. Yet, this level is based on the effectiveness of corrosion control; it has no relation to the associated health risks of lead exposure.

Yesterday, the Environmental Protection Agency (EPA) helped fill the void by releasing a draft report that provides three different approaches to setting a scientifically-robust “health-based benchmark” for lead in drinking water. The agency is seeking public comment on the draft and will convene a panel of scientific experts to consider each of the approaches.

The report is a critical step in implementing the recommendations of the agency’s National Drinking Water Advisory Council (NDWAC) which called for this type of health-based benchmark as part of an overhaul of the Lead and Copper Rule. The agency went a step further and provides alternatives to consider. We applaud EPA for its action and its rigorous, scientific analysis.

Accounting for the various models and assumptions, EPA developed a range of potential health-based benchmarks that range from 3 to 56 ppb of lead in water that people actually drink. However, you cannot readily compare these values to the typical water testing results reported by utilities or schools. Those tests are based on the first draw of water that has been sitting in the faucet and plumbing overnight and do not necessarily reflect what people drink over the course of a day. Later samples would likely be lower but could be higher if the building has a lead service line, especially if the line has been disturbed. Read More »

EPA proposes second rule to ban more uses of toxic TCE

Jennifer McPartland, Ph.D., is a Senior Scientist with the Health Program.

The Environmental Protection Agency (EPA) took another significant step yesterday to protect against exposures to the highly toxic chemical, trichloroethylene (TCE), proposing a rule to ban its use as a vapor degreaser.

The proposed rule is the second issued under section 6 of the Toxic Substances Control Act (TSCA) as amended by last year’s Lautenberg Act.  It follows on EPA’s proposed rule last month to ban the use of TCE as an aerosol degreaser and spot cleaning agent in dry cleaning facilities. Both proposed rules on TCE are critical to protecting consumer and worker health from the harmful effects of TCE and should move swiftly toward finalization.   Read More »
