EPA Finalizes Rule
on Modernizing Hazardous Waste Regulations for Ignitable Liquids Determinations
EPA finalized changes to the hazardous waste regulations that modernize how the hazardous waste characteristic of ignitability
is determined under the Resource Conservation and Recovery Act. The rulemaking, signed on June 8, 2020, allows the use of additional test methods (see SW-846 Methods 1010B and 1020C) that use modern equipment and techniques, including non-mercury thermometers,
for measuring the flash point of a liquid waste when determining if that waste is an ignitable hazardous waste. These changes reduce potential mercury exposures to humans and the environment by reducing the overall use of mercury-containing products.
This rule also revises the ignitability characteristic by defining the term aqueous in the regulatory exclusion for aqueous liquids
containing alcohols and updating cross references to U.S. Department of Transportation (DOT) regulations and making certain other conforming amendments. In addition, this rule is adding mercury thermometer alternatives in the air sampling and stack emissions test methods
in Test Methods for Evaluating Solid Waste: Physical/Chemical Methods (SW-846);
specifically, Methods 0010, 0011, 0020, 0023A, and 0051.

EPA Releases Guidance on COVID-19 Implications for Signing Paper Hazardous Waste Manifests
EPA released a temporary
guidance with respect to signatures on paper hazardous waste manifests under the Resource Conservation and Recovery Act
(RCRA) during the COVID-19 public health emergency. If obtaining a generator signature on a paper manifest is not reasonably practicable, entities can use a fully electronic manifest.
?If a fully electronic manifest is not a viable option, then the following steps should be taken: transporters should make certain notations on the hazardous
waste manifest form; generators should provide a signature substitute to the transporter and receiving facility; and all entities should retain documentation as provided in EPA's previously issued memorandum, COVID-19
Implications for EPA's Enforcement and Compliance Assurance Program.
This guidance is retroactive to March 13, 2020, and will continue in effect until revoked through additional public notification.

has been extended for an additional 60 days, through July 19, 2020. Learn
more on our website.

The purpose of this listserv is to provide stakeholders with updates about the federal solid
and hazardous waste programs. This listserv is used to send out announcements about rulemakings, upcoming webinars, guidance documents, open comment periods and other related communications.
