Washington is Cracking Down on Respirable Silica Exposure. Is Your Company Prepared?

In April 2018, Washington State adopted a rule that further regulates employee exposure to respirable crystalline silica (RCS), following OSHA’s publication of a similar—but less stringent—rule in 2016. Washington’s rule went into effect for the construction industry in October 2018 and will go into effect for occupations outside of construction on July 1, 2019.

Many companies are familiar with OSHA’s version of these rules and the general issues surrounding employee exposure to RCS. But with tighter regulation looming in Washington, here’s what you should know.

Crystalline silica is a mineral found in stone, soil, sand, concrete, brick, paints, plaster, and other materials often used in construction and industrial activities. It becomes respirable when those materials are cut, ground, drilled, crushed, or otherwise manipulated in a way that creates dust.

Inhaling dust that contains crystalline silica particles can lead to several health issues, including silicosis (an incurable lung disease), lung cancer, pulmonary disease, and kidney disease.

Who is at Risk for RCS Exposure?

According to OSHA, 2.3 million people in the U.S. are exposed to silica in the workplace. Industries with high exposure risk include construction, refining, mining, and manufacturing.

Washington State Regulation of RCS

Washington State’s rule is similar to the federal rule, but more stringent in some ways. In addition to setting standards on what concentration of RCS employees can be exposed to, the rule also lays out specific requirements related to:

  • Required assessment of employee exposure to RCS, including personal air sampling.
  • Exposure control methods, which define engineering controls and work practices related to 18 specific work tasks with high RCS exposure risk, including use of certain tools.
  • Required respiratory protection for employees.
  • Housekeeping/cleaning practices to minimize exposure risk.
  • Medical surveillance.
  • Training and recordkeeping.

What This All Means in Practice

Not only should companies operating in Washington consider a review to ensure that they are in compliance with the new rule, but there are permitting issues at hand as well. New permits may be required if a company is installing pollution control devices in response to the rule, or additional reporting on related emissions may be necessary.

SoundEarth frequently helps clients assess regulatory compliance related to RCS exposure and advises on needed workplace adjustments, permitting considerations, and other related issues.

The South Sound Environmental Managers Forum

SoundEarth covered the risks of RCS and the details of the new regulations at a recent presentation in our Tacoma office. This presentation was part of a series of events we host monthly, called the South Sound Environmental Managers Forum, aimed at providing timely information on topics affecting environmental professionals and providing an open dialogue and networking opportunity amongst industry peers. If you’re in Tacoma or the surrounding areas and work in a capacity similar to an environmental manager, please join us for the next Forum! Email us for more information.

SoundEarth Hosts First South Sound Forum; Summary of Dangerous Waste and Community Right-to-Know Reporting

Last Friday, SoundEarth hosted its first-ever South Sound Environmental Managers Forum in Tacoma. The idea behind this series of monthly events is to provide not only short, timely presentations on topics that affect environmental managers and their facilities, but also a place where they can share advice, ideas, concerns, and solutions with their peers away from the facility.

For our first round, we talked about Dangerous Waste and Community Right-to-Know Reporting. Here’s a peak at what we covered:

What is Solid Waste? What is Hazardous Waste?

We clarified RCRA’s definitions and the differences between listed hazardous waste and characteristic hazardous waste. In particular, here are the rules specific to listed waste that you should note:

Mixture Rule: A waste mixture that includes a RCRA-listed hazardous waste is automatically a RCRA-listed hazardous waste and carries the listing with the mixture. The chemical concentrations in the waste are irrelevant.

Derived from Rule: “Once a RCRA-listed hazardous waste, always a RCRA listed hazardous waste.” Waste generated from treatment, storage, or disposal is derived from a RCRA-listed hazardous waste. Ex. If listed waste is incinerated, the ash still carries the listed waste code even if the chemicals were destroyed during incineration.

Contained-in Rule: If you are disposing of soil or groundwater contaminated with a listed dangerous waste, you must manage the entire volume as if it were dangerous waste until it no longer contains the dangerous waste or is de-listed. Under Ecology’s contained-in policy, Ecology may determine that your contaminated soil or groundwater no longer contains a listed dangerous waste or is below risk-based levels.

Washington-Specific Waste Rules and Reporting

The “Dangerous Waste Regulations” are Washington State’s own set of rules that are more stringent than their federal counterparts, so we clarified the definitions of state-only dangerous waste and state-only special waste.

We also summarized what goes into Washington State’s Dangerous Waste Annual Report and who is required to submit one. There have been recent changes to the reporting system and to the requirements of the report. Most importantly, you should know:

  • Every site with an active EPA/State ID Number must submit a dangerous waste annual report to the Department of Ecology
  • Report Due Date: March 1
  • No extensions are given!
  • Submit all reports electronically through TurboWaste
  • 84-page guide for RY2018 available

Emergency Planning and Community Right-to-Know Act

The key purposes of EPCRA are to protect public health, safety, and the environment from chemical hazards; to create a partnership between, state, local agencies, tribal nations, and industry; to plan for emergencies and disasters; and to provide important information for first responders.

There are four reports that fall under EPCRA:

  • Emergency Response Planning
  • Emergency Release Notifications
  • Hazardous Chemical Inventory Reporting (Tier Two)
  • Toxics Release Inventory (TRI) Reporting  

This month, we covered Tier Two reports, their requirements and who is subject to them (tip, they’re also due March 1).

Next month, the South Sound Environmental Managers Forum will cover TRI Reports.
