The federal Clean Water Act (CWA) and state water quality laws (including California’s Porter-Cologne Water Quality Control Act) govern activities that may affect “waters of the United States.” Routine discharges from industrial and public sources make up most potentially polluting discharges, and are subject to National Pollutant Discharge Elimination System (NPDES) permits and California Waste Discharge Requirements (WDRs), but additional requirements also apply to potential “storm water” runoff from rainwater and snow, which can entrain oils and other pollutants and wash them down storm drains into water bodies. The US Environmental Protection Agency (EPA) established the first broad-based national program in 1990, and has revised and expanded requirements over the past quarter century (often in response to court decisions finding its efforts inadequate). States have followed suit. For example, in 2014 California updated its industrial storm water requirements, replacing a general permit adopted in 1997 with a new one that becomes effective on July 1, 2015. The new permit revises and expands requirements, including narrowing exemptions for “light industry” facilities to become conditional exemptions subject to certification requirements, and addition of detailed requirements for “preproduction plastic” materials. The remainder of this note summarizes the new California requirements, which generally are comparable to EPA’s national general permit (last updated in 2008)–so readers outside California should remember that your facilities face analogous responsibilities.

What is “green infrastructure”? Green infrastructure incorporates vegetation, soils, and natural processes to manage water and create healthier urban environments. When talking about an area the size of an entire city or county, green infrastructure refers to an assorted collection of natural areas that provide habitat, flood protection, cleaner air, and cleaner water. When referring to an individual neighborhood or smaller locale, green infrastructure refers to stormwater management systems that simulate nature by soaking up and storing water, which then can be redirected back into sustainable usage by those communities.

The Occupational Safety and Health Administration (OSHA) adopted massive changes to its Hazard Communication Standard (HCS or Hazcom) effective May 25, 2012, updating chemical information, labeling and training requirements that had been in place since the 1980s. These revised requirements conform U.S. requirements to international guidelines under the U.N.-sponsored Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Recognizing the extent of these changes, OSHA provided multi-year compliance phase-ins for employers whose workers manufacture, distribute or use chemicals. The next such deadline is June 1, 2015, when Safety Data Sheets (SDSs) must replace Material Safety Data Sheets (MSDSs) and end-user employers must ensure that their Hazcom programs reflect most of the revised requirements.

Two and a half decades ago, I left my home in Austin, Texas, armed with a BS in Civil Engineering from the University of Texas at Austin with an emphasis in water resources and environmental pollution control, and moved out to Los Angeles, California. My job as a young engineer was to be part of the Los Angeles Department of Water and Powers (LADWP) Superfund Group, a team in charge of assessing and cleaning up four federal Superfund sites in the San Fernando Valley (SVF) of southern California. Having taken Environmental Engineering 101 (“dilution is NOT the solution to pollution”), as well as classes in waste and hazardous waste management, hydrogeology, and many others, I felt ready to tackle the Superfund world…but what was it really?

As global attention to climate change and greenhouse gas (GHG) emissions has grown over the past two decades, California has been one of the leading jurisdictions. This began with statewide planning efforts in the 1990s, designed to identify and quantify GHG emissions. After the turn of the millennium it expanded to significant control requirements imposed on targeted source categories—notably a 2002 law (AB 1493) requiring the world’s first GHG emission limits on motor vehicles.

Last weekend’s disastrous earthquakes in Nepal are a reminder that natural disasters can strike anywhere. Employers can and should plan for a broad range of events, and can apply guidance from occupational safety and health agencies standards when doing so. The U.S. Occupational Safety and Health Administration (OSHA) requires employers with specified activities to prepare and implement emergency action plans (EAPs), provides guidance for EAPs, and recommends that all employers prepare these plans. Employers can use this structure to prepare for earthquakes.

Although water covers nearly three-quarters of the earth’s surface, only 0.033 percent of the world’s total supply is fresh water available for human use. Water is essential to every form of life, but is often taken for granted by consumers, who generally have maintained an attitude that plentiful water of the highest quality will always be available and is their right, a notion perpetuated by legislation. In 2013 the State Water Resources Control Board (SWRCB) established, under Section 106.3 of the California Water Code, that every human being has the inherent right to clean, safe, affordable, accessible, and adequate water for human consumption, cooking, and sanitation. That’s wonderful…when there is plenty of water to go around.

Although the pace of fracking projects rises and falls with changes in oil prices, regulation of fracking develops at slower and steadier rates. This month, the U.S. Bureau of Land Management (BLM) has completed nearly five years of rulemaking by revising its rules for oil and gas production from federal and Indian lands, to add requirements for hydraulic fracturing projects. These rules update and expand drilling permit rules in place for three decades. BLM reports that production from over 100,000 onshore oil and gas wells on federally-managed land accounts for 11 percent of U.S. natural gas supply and five percent of its oil, and that over 90% of wells currently being drilled on these land involve hydraulic fracturing.

My most recent blog provided a short summary of chemical evaluation and reporting requirements under the Toxic Substances Control Act (TSCA) of 1976. These requirements apply when a manufacturer or importer is preparing to introduce a “new chemical substance” into commerce in the U.S., to provide the Environmental Protection Agency (EPA) with information to evaluate whether chemical hazards require regulatory restrictions (up to and including outright bans) to provide adequate protections to human health and the environment. TSCA does not include any blanket requirement for ongoing studies or updated evaluations of an “existing chemical substance” after it has entered commerce—including those already in commerce when TSCA took effect, so some chemicals have never undergone a regulatory review of their hazards.
