Regulatory and Legal Compliance Flashcards

A water utility is expanding its service area, which involves installing new water mains. According to the Safe Drinking Water Act (SDWA), which of the following is a primary responsibility of the utility regarding the new infrastructure?

Answer: To ensure the new pipes and materials do not introduce lead into the drinking water.

The Safe Drinking Water Act (SDWA) includes the Lead and Copper Rule, which regulates lead and copper concentrations in drinking water. A key provision of this rule is to control corrosion and prevent the leaching of lead from plumbing materials, including new pipes, into the water supply. Utilities must ensure new infrastructure does not become a source of lead contamination.

A wastewater treatment plant manager discovers an equipment malfunction that could lead to the discharge of pollutants exceeding the limits specified in their National Pollutant Discharge Elimination System (NPDES) permit. Under the Clean Water Act (CWA), what is the manager's most critical and immediate legal obligation?

Answer: To notify the appropriate regulatory agency of the potential non-compliance.

The Clean Water Act (CWA) requires facilities with an NPDES permit to report any non-compliance that may endanger health or the environment. This notification must be made to the regulatory authority (like the EPA or a state agency) within a specified timeframe, often 24 hours, allowing the agency to take appropriate action to protect water quality.

Which of the following best describes the 'revenue requirement' in the context of utility rate-setting regulation?

Answer: The total amount of money a utility needs to collect from customers to cover its operating expenses, taxes, depreciation, and earn a reasonable return on its investments.

The revenue requirement is the foundation of utility ratemaking. It represents the total costs the utility prudently incurs to provide service, plus a fair return on the capital invested in its infrastructure (the rate base). State public utility commissions review and approve this amount in a formal rate case proceeding.

An electric utility crew is tasked with performing maintenance in an underground vault containing energized electrical equipment. According to Occupational Safety and Health Administration (OSHA) regulations, which safety measure is specifically required for this situation?

Answer: Having an employee trained in first aid available on the surface in the immediate vicinity.

OSHA standard 1926.965(d) explicitly states that while work is being performed in a manhole or vault containing energized electric equipment, an employee with first-aid training must be available on the surface near the entrance to render emergency assistance. This ensures a rapid response in case of an incident.

A public utility commission (PUC) is reviewing a request for a rate increase from an investor-owned electric utility. The primary legal standard the PUC must apply when evaluating the proposed rates is that they must be:

Answer: Just and reasonable.

The foundational principle of public utility regulation is that rates must be 'just and reasonable'. This means they must be fair to consumers while also being sufficient to cover the utility's prudent costs and provide an opportunity (not a guarantee) for investors to earn a reasonable return on their investment, ensuring the utility's financial health and ability to provide safe, reliable service.

Under the Clean Water Act, which of the following is considered a 'point source' of pollution and would require an NPDES permit to discharge into navigable waters?

Answer: A pipe discharging treated wastewater from a municipal sewage plant.

The Clean Water Act defines a point source as any 'discernible, confined and discrete conveyance,' such as a pipe, ditch, or channel, from which pollutants are or may be discharged. A pipe from a wastewater treatment plant is a classic example of a point source that requires an NPDES permit to legally discharge treated effluent.
