Revised SNUR Rule - EPA Amendment to TSCA

EPA is promulgating Significant New Use Rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 23 chemical substances which were the subject to premanufacture notices (PMNs). Four of these chemical substances are subject to TSCA section 5(e) consent orders issued by EPA.

The amended rules require persons who intend to manufacture, import, or process any of these 23 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. According to EPA, the notification is needed to provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

The Minnesota Pollution Control Agency (MPCA) has finalized waste and material removal rules that apply to all renovation or demolition projects. According to the revised Rules, the following items and materials must be removed prior to the commencement of renovation or demolition:

A. items that would normally be disposed of as mixed municipal solid waste, such as furniture, carpeting, bedding, mattresses, clothing, small appliances, food, and food waste;
B. household hazardous waste including;
F. items that may contain elemental mercury:
G. items that may contain polychlorinated biphenyls (PCBs);
H. items that may contain chlorofluorocarbons (CFCs):
I. oils, including used oil, hydraulic oils, and oils located in heating oil tanks, piping, sumps, and traps;
J. lead-containing items, including lead-acid batteries, lead pipes, lead sheeting, lead flashing in roof vents, and lead paint that is not firmly adhered to the substrate; and
K. electronic products containing a cathode ray tube, including televisions and computers;

An exemption from this requirement exists for items or materials that are within components of the structure, such as elevators, vertical lifts, or lighting, that need to remain intact are being used during the course of renovation or demolition, provided that the items or materials are removed after use of the component is no longer required for renovation or demolition work.

If the owner, person authorizing renovation or demolition, or person conducting the renovation or demolition knows or has reason to know that portions of the structure may be contaminated by hazardous substances or petroleum based on past uses of the structure, such as a medical building, laboratory, or manufacturing facility, they must obtain appropriate samples and receive results from laboratory analysis as necessary to ensure the proper management and disposal of contaminated structural elements and any resulting debris generated.

(B) all interstate waters, including interstate wetlands;
(C) all other waters, such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds;
(D) all impoundments of waters of the United States;
(E) tributaries of the aforementioned waters;
(F) the territorial seas; and

US EPA Extends SPCC Rule Deadline

Facilities subject to Spill Prevention, Control & Countermeasure (SPCC) requirements have more time to amend their programs. On June 11, 2009, EPA again extended the compliance date for compliance with the federal "SPCC Rule". Facilities subject to the SPCC Rule now have until to November 10, 2010 to come into either amend their existing SPCC Plan or prepare an inital Plan, if they are newly subject to the Rule.

Facilities must amend or prepare, and implement SPCC Plans by the compliance date in accordance with revisions to the SPCC rule promulgated since 2002. Farms that are also subject to the Rule must also amend or prepare their SPCC Plans, and implement those Plans by the same date.

NY Proposed Rules for Used Electronic Equipment - CRT

The New York State Department of Environmental Conservation (NYSDEC) is currently drafting a proposed rules for the management of used electronic equipment. Posting of the preliminary draft regulation is anticipated for Spring 2009, followed by further opportunity for public comment.

The resulting proposed rulemaking will amend NYSDEC regulations to streamline the management of used electronic equipment, whether regulated as hazardous waste or solid waste. The main issues to be addressed in the proposed rulemaking are:

• Adopting provisions of the Federal Cathode Ray Tube (CRT) Rule


• Adopting management standards for Collectors, Dismantlers, and Recyclers of Used Electronic Equipment


• Adopting provisions of the New York State Wireless Telephone Recycling Act


• Amending the requirements of New York's current Generator "c7" Notification

Currently in NYS, intact CRTs destined for recycling are eligible for the hazardous scrap metal exemption. However, when the CRT glass is no longer adherent to the metal, CRT glass could be regulated hazardous waste. The Federal CRT Rule contains the provisions to conditionally exclude this CRT glass from hazardous waste rules.

The current c7 notification requirements require generators (other than CESQGs) sending used electronics for recycling under the hazardous scrap metal exemption to file notifications. In the rulemaking, the NYSDEC is proposing to change the requirement to “[generators] must maintain on site, for a period of three years from the date of each shipment, the names and locations of the dismantling or recycling facilities and any intermediate receiving facilities."

EPA Excludes Water Transfer From NPDES Requirements

EPA is publishing a final rule to exclude water transfers from regulation under the NPDES permitting program. The final rule defines a water transfer as an activity that conveys or connects waters of the United States without subjecting the transferred water to intervening industrial, municipal, or commercial use. This does not apply to pollutants introduced by the water transfer activity itself to the water being transferred.

Water transfers are activities that divert water between waterbodies, typically through the use of pumps or passive redirection through tunnels, channels, and/or natural stream water features. Water transfers are necessary to allocate water resources to meet the water needs of those downstream in the receiving waterbody. Such needs include public water supply, irrigation, power generation, flood control, and environmental restoration.

The Bureau of Reclamation administers significant transfers in western States to provide approximately 140,000 farmers with irrigation water. With the use of water transfers, the Army Corps of Engineers keeps thousands of acres of agricultural and urban land in southern Florida from flooding in former areas of Everglades wetlands. Many large cities in the west and the east would not have adequate sources of water without continuous redirection of water from outside basins. Both the cities of New York and Los Angeles are dependent on water transfers from distant watersheds to meet their municipal demand.

MassDEP Limits Mercury in Industial Wastewater Discharges

Massachusetts Department of Environmental Protection (MassDEP) restrictions on mercury discharges to municipal sewer systems go into effect on May 1, 2009. These rules, promulgated under the Massachusetts Mercury Management Act, limit the maximum concentration of mercury in sanitary sewer discharges from industrial users to less than 1 ug/L (1 ppb). By July 2007, all dischargers were to have determined possible sources of mercury in their discharges and have taken reasonable steps to eliminate them.

[What is 1 ug/L (parts per billion) mercury equivalent to?]
