CHMP cheat sheet

RCRA hazardous waste identification uses two tests: listed wastes (F, K, P, U lists in 40 CFR 261 Subpart D) and characteristic wastes (ignitability, corrosivity, reactivity, toxicity via TCLP in Subpart C).

A solid waste is excluded from RCRA Subtitle C if it is a household waste, agricultural waste, or a listed exclusion under 40 CFR 261.4; exclusions must be documented before any disposal decision.

DOT hazard classification (49 CFR 173) assigns hazard class, division, packing group, and UN/NA number; the shipping paper, package markings, and placards must all agree with that classification.

Packing group I, II, III corresponds to great, medium, and minor danger; PG I materials drive the most stringent packaging, segregation, and quantity limits.

Hazardous waste generator status depends on monthly generation: very small quantity generator (<=100 kg/mo), small quantity generator (100-1000 kg/mo), and large quantity generator (>1000 kg/mo).

CERCLA reportable quantity release notification to the National Response Center is required when a release of a hazardous substance exceeds its RQ within 24 hours (40 CFR 302.6).

SARA Title III Tier II reporting (EPCRA Section 312) applies to facilities storing hazardous chemicals at or above threshold planning quantities; SDSs fall under EPCRA Section 311.

OSHA HAZWOPER (29 CFR 1910.120) sets training levels: 40-hour for general site workers, 24-hour for occasional site workers, and 8-hour annual refresher for both.

The DOT segregation table (49 CFR 177.848) prohibits loading certain hazard classes together, for example cyanides with acids and oxidizers with flammable liquids, unless specific exceptions apply.

The incident command system places the incident commander at the top; operations, planning, logistics, and finance/administration sections report to command, and safety officer reports directly to the IC.

Defensive operations stop at the control zones, while offensive operations require structural firefighting PPE plus chemical protective clothing and SCBA; the choice depends on the substance and mission.

Control zones are hot (exclusion), warm (contamination reduction), and cold (support); the contamination reduction corridor is established in the warm zone.

The emergency response guidebook provides initial isolation distances and protective action distances by guide number; the green tables give large and small spill distances.

The ERG guide number and the DOT placard or UN number determine initial isolation; the guide number is not the same as the UN number.

Decontamination is set up before entry, with a contamination reduction corridor, and all personnel and equipment leaving the hot zone pass through it.

A site safety plan under 29 CFR 1910.120(b) includes the site characterization, control zones, medical surveillance, and emergency response procedures.

The planning process includes hazard analysis, capability assessment, and a written emergency response plan reviewed annually; drills and exercises test the plan and identify gaps.

For a release, the notification chain typically starts with the internal emergency coordinator, then local emergency responders, then state and federal agencies as required by the release quantity.

A sampling and analysis plan documents the objectives, sampling design, number of samples, analytical methods, and quality assurance/quality control criteria before field work begins.

The chain of custody form records sample identity, collection time, preservatives, and transfer signatures; a break in custody can invalidate the sample for regulatory purposes.

Air sampling uses either active methods (pump and sorbent tube or filter) or passive methods (diffusive badge); the method detection limit and sampling rate determine the minimum sample volume.

Water samples are collected in the order of volatile organic compounds first, then metals, then general chemistry, to reduce cross-contamination and preserve volatiles.

Soil sampling uses a grid or stratified random design; composite samples represent an area, while discrete samples are needed to delineate a hot spot.

SW-846 methods (for example 8260 for VOCs, 8270 for semivolatiles, 6010/6020 for metals) are the standard RCRA analytical methods; method selection must match the regulatory decision.

Quality control samples include field blanks, trip blanks, duplicates, matrix spikes, and matrix spike duplicates; the relative percent difference and percent recovery are the acceptance criteria.

The method detection limit is the minimum concentration that can be measured and reported with 99% confidence that the analyte concentration is greater than zero.

Holding times and preservation (for example, nitric acid to pH < 2 for metals, hydrochloric acid for volatiles) must be met or the data are flagged as estimated.

The site investigation phases are preliminary assessment, site inspection, remedial investigation, and feasibility study; the RI/FS characterizes the nature and extent of contamination and evaluates remedial alternatives.

A conceptual site model links sources, release mechanisms, exposure pathways, and receptors; it drives the risk assessment and the remedial decision.

The risk assessment follows the four-step process: hazard identification, dose-response assessment, exposure assessment, and risk characterization.

Remedial alternatives are compared on nine criteria under CERCLA: overall protection, compliance with applicable requirements, long-term effectiveness, reduction of toxicity, short-term effectiveness, implementability, cost, state acceptance, and community acceptance.

In-situ remediation includes soil vapor extraction, air sparging, bioremediation, chemical oxidation, and thermal treatment; ex-situ treatment includes excavation with soil washing or incineration.

Groundwater remediation options include pump-and-treat, permeable reactive barriers, monitored natural attenuation, and in-situ chemical reduction.

Institutional controls such as deed restrictions, zoning, and groundwater use restrictions are used when waste remains in place and must be maintained and monitored.

The remedial action objectives define the cleanup levels, media, and timeframe; cleanup levels are often risk-based or derived from applicable or relevant and appropriate requirements.

Long-term monitoring verifies remedy performance and confirms that contaminant concentrations trend toward the remedial goals.

A hazardous materials management program includes inventory, storage, handling, training, emergency response, waste minimization, and regulatory reporting elements.

The project management triangle balances scope, schedule, and cost; changes to one element require re-baselining the others and documenting the change control.

A work breakdown structure decomposes the project into deliverables; each work package has an owner, duration, and cost estimate.

Regulatory compliance calendars track permit renewals, Tier II reporting (March 1), toxic release inventory reporting (July 1), and biennial hazardous waste reports.

Training records must document the employee name, training date, and content; HAZWOPER requires annual refresher training and medical surveillance for covered workers.

Contractor management includes pre-qualification, safety plans, and a defined interface with the facility emergency plan; contractor and host employer responsibilities must be coordinated.

Key performance indicators for a hazmat program include training completion rate, inspection findings, spill rate per unit of throughput, and waste generation per unit of production.

A corrective action process documents the finding, root cause, corrective action, responsible party, and verification of closure.

Budgeting for a hazmat program covers personnel, equipment, training, disposal costs, permits, and contingency for emergency response.
