Current Cal/OSHA regulations, CCR T8 §342(a), require that “every employer shall report immediately by telephone or telegraph to the nearest District Office of the Division of Occupational Safety & Health any serious injury or illness, or death of an employee occurring in a place of employment or in connection with any employment. Immediate means as soon as practically possible but not longer than 8 hours after the employer knows or with diligent inquiry would have known of the serious injury or illness. If the employer can demonstrate that exigent circumstances exist, the time frame for the report may be made no longer than 24 hours after the incident.”
Alta|NV5 Invited Participant in ASCE Future World Vision Summit and Sponsors ASCE International Conference on Sustainable Infrastructure
Alta|NV5’s Lisa Kay was part of the Future World Vision Leadership Summit, an invitation only full-day event immediately preceding the ASCE International Conference on Sustainable Infrastructure in November 2019. The Summit brought together business, industry, and government leadership from across the world to develop proposed actionable solutions toward improving infrastructure resilience to meet the future world’s needs. This summit resulted in commitments from attendee organizations and ASCE to take proactive steps toward ensuring more resilience in our work and increased industry standards. NV5 has made a proactive commitment to infrastructure resilience as active thought leaders contributing to infrastructure sustainability. NV5 is a charter member of the Institute for Sustainable Infrastructure and a member of the Zofnas Sustainable Infrastructure Board at Harvard where NV5 is well represented by Linda Reardon and Kathy Collins.

What you need to know before sampling for PFAS
For the past several years, programs and research studying Per- and polyfluoroalkyl substances (PFAS) have rapidly increased across the country. Although PFAS have been in use since the 1940s, public awareness of the environmental and health risks posed by PFAS began at the turn of the century. This increased public concern led to a voluntary phase out of perfluorooctanoic acid (PFOA) in all US manufacturing processes. However, PFOA is still used in manufacturing processes world-wide and is used to manufacture products imported into the US. Also, PFOA is only one type of PFAS chemical and there are many more PFAS chemicals in use. The Environmental Protection Agency (EPA) launched a stewardship program in 2006 to monitor these chemicals and to investigate their potential dangers. Research will continue over the coming years, and new articles are posted weekly about the topic. Staying aware of the latest information about PFAS will help when the time for new regulation measures comes to pass.
Chrome Plating Facilities be advised! Phase II of the State Water Board’s PFAS Investigation Order were mailed out on October 25, 2019
By: David Renfrew, Vice President, Water Resources Director at Alta Environmental|NV5
On October 25, 2019, the State Water Resources Control Board (SWRCB) issued Investigative Order WQ 2019-0045-DWQ (Order). This was the second phase rollout of the SWRCB’s three phased investigation of per- and polyfluoroalkyl substances (PFAS) listed in SWRCB Resolution No. 92-49. The SWRCB already directed PFAS testing at 30 airports and 196 landfills, and intends to target other potential PFAS sources in the state to do the same. This second phase roll out listed chrome plating facilities in California that have stored and/or used fume suppressants or other substances that may contain PFAS and are required to submit information to the appropriate Regional Water Quality Control Board (RWQCB).

By Steve Ridenour, PG, from Civil + Structural Engineer on Enhanced In-Situ Bioremediation (EISB) technology
Elevated levels of chlorinated solvent compounds, such as tetrachloroethene (PCE) or trichloroethene (TCE), are often present in groundwater beneath sites where manufacturing and industrial operations have occurred. An innovative technology known as Enhanced In Situ Bioremediation (EISB) is being used to cost-effectively treat these contaminated sites. EISB, or engineered bioremediation, is the acceleration of microbial activities to enhance the degradation or detoxification of environmental pollutants in an anaerobic environment. The purpose of EISB is to increase the rate of microbial activity so the rate of reductive dechlorination is increased.

Water quality managers may be implementing Best Management Practices (BMPs) using both administrative and structural controls, yet the water quality compliance results still are over permitted limits. Managers may need answers as they report to upper management or regulatory agencies on why BMPs are not performing as expected. Facility and municipal compliance managers need to understand frequent assessment of BMPs is required to evaluate their applicability, effectiveness and maintenance requirements.
The official “rainy season” for Southern California started on October 1 and continues through April 30, 2020. Rainfall events typically begin to arrive in October and continue with more frequency as we get into November and December. That said, we are more than halfway through October and there isn’t much rain in sight through Halloween. With the current above average temperatures forecast to continue well into fall, there may be a late onset of rainfall events for Southern California. Here is a summary of the winter weather outlook through the end of 2019:
The three-month seasonal temperature and precipitation outlooks shown below from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center generally favor above-average temperatures across much of the United States, including the Southwest, and below normal to normal precipitation for California.

After a year-long effort, South Coast Air Quality Management District (SCAQMD, District) has published the draft Community Emission Reduction Plan (CERP) for the three “Year 1” communities within the District that were chosen as part of California Air Resources Board (CARB) Assembly Bill 617 (AB 617). The Year 1 communities are:
