Right-to-Know, Worker Safety Regulations, and Chemical Reporting

Why Right-to-Know Laws Exist

Water and wastewater facilities store and use chemicals that can injure workers, harm the public, and damage the environment if mishandled. Two sets of federal rules address this risk from different angles. The OSHA Hazard Communication Standard (HazCom) protects workers by ensuring they know what chemicals they are exposed to and how to handle them safely. SARA Title III, also called the Emergency Planning and Community Right-to-Know Act (EPCRA), protects the surrounding community by requiring facilities to disclose what hazardous chemicals they store.

As a licensed operator you are legally responsible for complying with both frameworks. Ignorance of a deadline or threshold is not a defense.

OSHA Hazard Communication Standard (HazCom / GHS)

The HazCom standard (29 CFR 1910.1200) requires employers to give workers information and training on every hazardous chemical present in the workplace. The standard is built around three tools.

Safety Data Sheets (SDS)

An SDS must be maintained for every hazardous chemical on site and must be immediately accessible to workers at all times during a shift. The standard requires 16 sections in a specific order, based on the Globally Harmonized System (GHS). Key sections operators use daily include:

• Section 1 – Identification (product name, supplier, emergency phone)
• Section 2 – Hazard identification (signal word: DANGER or WARNING)
• Section 4 – First-aid measures
• Section 6 – Accidental release measures (spill response)
• Section 8 – Exposure controls and PPE (gloves, respirator type, eye protection)
• Section 14 – Transport information

For chlorine gas, Section 8 will specify a supplied-air respirator (SCBA or supplied-air) because the immediately dangerous to life or health (IDLH) concentration is very low. Never substitute a cartridge respirator for chlorine gas work unless the SDS and your facility's respiratory protection program specifically authorize it.

GHS Labels

Every container must bear a GHS-compliant label showing the product identifier, signal word, hazard pictograms, hazard statements, precautionary statements, and supplier contact information. If you transfer a chemical into a secondary container, that container must also be labeled unless you will use it and finish it within the same shift.

Employee Training

Workers must be trained before first assignment to a job involving hazardous chemicals and whenever a new hazard is introduced. Training must cover how to read an SDS, what the label elements mean, and what protective measures to take.

SDS Library Obligation

Maintain a complete, current SDS library—paper binders, electronic system, or both—so that every worker can access any SDS without delay. Conduct annual audits to confirm every chemical in inventory has a matching SDS and that outdated sheets are replaced.

SARA Title III: Community Right-to-Know Reporting

SARA Title III (EPCRA, 42 U.S.C. § 11001 et seq.) created a system for communities and emergency responders to know what hazardous materials are stored nearby. Two sections matter most to operators.

Sections 311 and 312: Tier II Reporting

Section 311 requires facilities subject to OSHA HazCom to submit SDS documents (or a list of chemicals) to the State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC), and local fire department when a chemical is first stored above its threshold quantity.

Section 312 requires facilities to submit an annual Tier II Emergency and Hazardous Chemical Inventory Form for any hazardous chemical stored on site at or above its threshold quantity at any point during the previous calendar year.

Threshold quantities under SARA Title III:

• Extremely hazardous substances (EHS): 500 pounds or the threshold planning quantity (TPQ) listed for that substance, whichever is lower. Chlorine gas is an EHS.
• All other OSHA hazardous chemicals: 10,000 pounds.

Sodium hypochlorite solution (liquid bleach) is an OSHA hazardous chemical but is not an EHS, so the 10,000-pound threshold applies to it.

Annual Tier II deadline: Reports covering the previous calendar year are due March 1 of each year.

Who receives the report: The SERC, the LEPC for the district where the facility is located, and the local fire department. Many states now require electronic submission through EPA's Tier2 Submit software or a state portal.

Information reported on Tier II: Chemical name or common name, CAS number, maximum and average daily amount stored, storage location on the property, and whether the chemical is stored in a particular container type.

Safety Priorities for Chemical Handling

HazCom and SARA compliance does not by itself make a facility safe—it provides the information framework. Always layer in these practices:

• Lockout/Tagout (LOTO): Before any maintenance on a chemical feed system (chlorine injector, chemical pump), follow your facility's written energy control procedure.
• PPE selection: Match PPE to the SDS. Chlorine gas requires SCBA; sulfuric acid requires chemical-splash goggles and acid-resistant gloves and apron. Never guess.
• Spill response: Know your facility's Emergency Response Plan and the spill procedures in SDS Section 6 before an incident occurs.
• Emergency contacts: Post LEPC, SERC, and CHEMTREC contacts prominently in the chemical storage area.

Putting It Together

As an operator, your daily obligations are straightforward: keep the SDS library current and accessible, ensure every container is properly labeled, make sure workers are trained, and track chemical inventory quantities against SARA thresholds. Every March 1, review last year's chemical inventory and file Tier II reports for any chemical that exceeded its threshold. Document everything. State inspectors and LEPC members may request records at any time.
