EPA Announces Draft Risk Evaluation for N-Methylpyrrolidon (NMP)

Earlier this month, the U.S. Environmental Protection Agency (EPA) announced the availability of the draft risk evaluation for N-methylpyrrolidon (NMP) under the Toxic Substances Control Act (TSCA). The purpose of a risk evaluation is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of its use and to analyze the risks from potential exposure. The draft risk evaluation will be peer-reviewed by the TSCA Science Advisory Committee on Chemicals (SACC) on December 5- 6, 2019 with a final regulation

EPA’s Supplemental “Transparency in Regulatory Science” Rule Likely to Restrict the Use of Scientific Studies in Determining Pivotal Environmental Actions

The U.S. Environmental Protection Agency (EPA) is planning to publish a supplemental proposed rule that would expand the applicability of a preexisting proposed rule from 2018 impacting how environmental regulations come about.  The supplemental proposal would require underlying data in scientific studies used in the promulgation of significant regulatory actions be publicly available—underlying data that’s often confidential, proprietary, and may contain private personal information subject to confidentiality agreements.  As reported by the New York Times, this rulemaking action would supplement the April 2018 proposed rule entitled “Strengthening Transparency in

Inspector General Directs the EPA to Improve Oversight of Public Drinking Water Regulations

The Office of the Inspector General (OIG) issued a report that found the EPA is failing to properly monitor state-level compliance for violations of the Safe Drinking Water Act (SDWA). Federal regulations mandate that public water systems notify consumers of violations of the national drinking water standards or in situations that pose a risk to the public. These violations and situations are divided into three tiers with specific notice requirements. Under the SDWA, 49 states and certain territories are responsible for implementing the

EPA Taps Public for Comment on Water Reuse Plans

Water scarcity is a growing concern for the EPA, as discussed in depth in its National Water Reuse Action Plan issued this week. The plan outlines ways that the EPA can work with state and local governments to promote water reuse and support research into new technologies. Due to various pressures, 80 percent of U.S. states anticipate water shortages in some parts of their states in the next decade. Over the past several decades, agriculture, industry, and communities have faced

SSRA 2.0: New Jersey Makes Changes to its Privatized Site Contamination Remediation Law

On Friday, August 23, 2019, Gov. Murphy signed into law an amendment to New Jersey’s 2009 Site Remediation Reform Act (SSRA)—a law that privatized many responsibilities previously handled by the New Jersey Department of Environmental Protection (NJDEP) concerning the remediation of contaminated sites. The SSRA created what is called the Licensed Site Remediation Professional (LSRP) program; LSRPs are experienced, private sector environmental professionals that are licensed by the state and hired by Responsible Parties (RPs) to direct and oversee environmental
