OSHA leaves a big hole in Confined Space Entry curriculum. It's Gas Monitor Competence Training!

CSE training by itself leaves workers ill equipped to use a gas monitor and with a false sense of security. Every brand of gas monitor is different. It is absolutely necessary for workers to understand the varied buttons, alarm settings, lights and sounds, sensors, pump speeds, etc., in order to know what to do and not do when facing the very real danger of entering a confined space.

This 45 min presentation includes:
An overview of Gas Monitor Competence Training
How Gas Monitor Competence Training completes Confined Space Entry training
How Gas Monitor Competence Training differs among gas monitor brands
How training practices differ among manufacturers, distributors, government, and users
Why OSHA Confined Space Entry Training does not include Gas Monitor Competence Training
Ways to ensure more complete training for confined space workers

Three Takeaways:
Get insights on how to help your workers become knowledgeable, confident, and safe with their gas monitors.
Learn what prevents OSHA, manufacturers, and distributors from providing gas detector training and how to fill this gap.
See why Gas Monitor Competence Training is the difference between “compliant” and “safe”.

Growing concerns associated with contaminants of emerging concerns (CECs) (especially PFAS), greenhouse gas emissions, and regulations have begun to limit the end-use alternatives for biosolids. In response to these pressures, biosolids producers are considering new and innovative treatment options that require a new perspective to the historical understanding of biosolids treatment and end-use. Orange County Sanitation District (OC San) has embarked to seek a new technology, Supercritical Water Oxidation (SCWO) to diversify their end products from water reclamation facilities (WRRFs). OC San teamed with 374Water that is collaborated Hazen and Sawyer, and Merrell Brothers to demonstrate this technology at their site. SCWO is a promising technology that converts organic material (biosolids) to inert gases, minerals and water. Water above 374°C and 22.1 MPa becomes supercritical, a special state where organic solubility increases, and oxidation processes are accelerated.

SCWO has been recently shown to destroy hazardous substances such as halogenated compounds including poly-fluoroalkyl substances (PFAS). Studies showed a greater than 99% reduction of the total PFAS identified in a targeted compound analysis, including perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) (Krause et al, 2022). As a destructive technology, SCWO is proposed as an alternative to incineration and other combustion processes and could be a permanent solution for PFAS-laden biosolids or solid matrices. However, additional investigation of reaction byproducts: water, solids and air emissions need to be conducted for a complete assessment of SCWO’s potential as a safe and effective technology.

OC San is located in South Coast Air Quality Management District (SCAQMD) and an air permit is required for this demonstration project. The research team, including OC San (a Utility), 374Water (a private firm-technology provider), Hazen and Sawyer (a consulting firm), Yorke Engineering (permitting support), Alliance Testing (a source testing firm) worked together to develop a rigorous test plan and granted a research permit to implement SCWO at Plant 1. This presentation will focus on the technology and design details, and provide the steps taken to implement this technology at OC San. The information will benefit utilities that seeks sustainable solution for their biosolids management considering recent end-use restrictions."

Learning Objectives:
Define supercritical water oxidation process and list the advantages/disadvantages of this innovative technology
Describe the steps to take to implement SCWO
Identify the testing necessary to permit SCWO facility."

In California WRRFs are facing uncertainty with their current land application programs related to anticipated PFAS regulations. In addition, with the diversion of organics from landfills by SB 1383 the main strategy is co-digestion followed by composting to produce a Class A biosolids for beneficial use. However, with the emerging challenges related to PFAS, the composting part of this strategy may be impacted as it does not provide any PFAS treatment. On the other hand, drying produces Class A biosolids and is required upstream of advanced thermal processes for PFAS treatment including pyrolysis and gasification. Drying the dewatered digestate rather than composting provides an opportunity to limit the impacts of anticipated PFAS biosolids regulations.

This presentation will cover three thermal drying case studies that will benefit utility managers, operation and maintenance practitioners, and engineers by providing:
• a highlight of the thermal drying sizing, technology selection, and dried product characteristics,
• system integration with existing WRRFs including sludge conditioning,
• the lessons learned including equipment procurement, staffing, and challenges in operation from previous thermal drying designs., and
• integration insights for future pyrolysis/gasification PFAS treatment.

Attendee Takeaways:

Conduct thermal drying sizing, technology selection, and describe the dried product characteristics.
Understand system integration with existing and future solids treatment.
Define project delivery and operations based upon lessons learned from thermal drying case studies."

This presentation will review the cost to manage biosolids in various New England states, and the impact that PFAS has had on utilities’ operating budgets and operations for biosolids management. Maine’s land application moratorium, signed by the governor, will be discussed, including its short- and long-term impacts. The reactions of nearby states such as New Hampshire, Vermont, and Massachusetts’s to EPA’s PFAS roadmap; Maine’s moratorium; and growing negative public perception will be reviewed such that California agencies can learn from New England utilities’ experiences. We will also review successes in these states, where progress has been made working with regulators, communities, activist groups, and local legislative bodies.

EPA currently has not set any policies on PFAS in NPDES permitting, nor PFAS in biosolids. However, CERCLA has recently proposed designation of PFOS and PFOA as hazardous materials, which could impact water reclamation facilities and potential liabilities. States are taking matters into their own hands, ranging from a “do-nothing” approach to instituting a statewide ban on the land application of biosolids (Maine) which has severely disrupted biosolids management . Many states are moving toward “report only” requirements in NPDES permits for influent, effluent, and biosolids to increase the database of PFAS in the environment.

What should California do? To date, most states have not imposed PFAS standards in NPDES permits or biosolids, but Michigan’s EGLE has done precedent-setting work on PFAS in WW and mitigating sources. Utilities and consultants need to be prepared to educate communities, the legislature, regulators, and other stakeholders on the direct and indirect impacts of regulations and legislation around PFAS and water reclamation facilities. Industries discharging to WRFs need to participate in the conversation and become part of the solution through source control. In parallel, the science needs to continue to be developed and expanded, to better understand the true health and environmental implications of these compounds. This presentation aims to continue the conversation and information sharing so measured and thoughtful actions can be taken to address this issue in a fiscally and environmentally responsible manner, and so Californians can benefit from and implement the best practices.

Attendee Takeaways: 
Understand the value of biosoli.
Understand the value of biosolids to our communities and impact of PFAS regulations.
Success ways to communicate with regulators, legislature and other key stakeholders.
Understand the state of the science and current understanding of PFAS in Biosolids.ds to our communities and impact of PFAS regulations."

As more WRRFs in California implement potable reuse schemes, and the impact of nutrients on coastal waters is recognized, biological nitrogen removal is expected to expand dramatically along the coast. Upgrading to nitrogen removal can significantly increase the cost, energy use, operational complexity, footprint requirement and climate impact of these facilities, and so determining the most efficient and sustainable treatment strategy is critical. Anammox is a unique biology that has been widely implemented in sidestream treatment to reduce costs and improve sustainability and efficiency, but this technology has not yet been implemented widely in mainstream secondary trains. This presentation will review two new technological developments that promise to bring the benefits of Anammox biology to mainstream secondary treatment.

First, we will describe the challenge of adapting the partial-nitration/Anammox process (PN/A) from hot, concentrated centrate treatment to dilute, cool secondary treatment. This strategy boasts the highest potential reductions in aeration energy, carbon requirements and sludge production, but is also the most challenging to operate and maintain. Challenges associated with NOB inhibition will be discussed, and a novel strategy, developed by Tomorrow Water and demonstrated with Black & Veatch at the Hyperion Water Recovery Plant in LA, will be described. We will share data from lab and pilot-scale facilities, highlighting the newest developments in process design and the relationship of critical control variables (inhibition frequency, temperature, nitrogen species ratio, etc.) We will also discuss the knowledge gaps that remain in order to bring this novel strategy into wide implementation.

Secondly, we will describe an alternative strategy for mainstream Anammox implementation: partial denitrification/Anammox (PdN/A). This strategy was developed in plants in the mid-Atlantic, and is now being commercialized for deployment in California (and worldwide). The process uses the same Anammox biology, but in concert with different supporting organisms (heterotrophic denitrifiers instead of ammonia-oxidizing bacteria.) This presentation will compare PN/A and PdN/A strategies, explaining the differences in process design, control, and achievable efficiency gains between the two different strategies. Participants will be provided with hypothetical plant scenarios and polled to determine which of the two strategies would be more applicable in a given context

Learning Objectives:
Quantify the benefits of the mainstream anammox process in terms of energy, carbon requirements, sludge production and plant intensification.
Differentiate between the two distinct implementation strategies of mainstream anammox (PN/A vs PdN/A) and understand their comparative advantages and challenges
Describe a novel PN/A strategy piloted at Hyperion WRP, and how this strategy fits in to the larger industry effort to commercialize mainstream PN/A for improved plant efficiency and sustainability
