REP study plan

Map every U.S. federal environmental statute that appears in the exam blueprint (CAA, CWA, RCRA, CERCLA, EPCRA, TSCA, SDWA, NEPA) to its core obligation, administering agency, and primary regulatory citation

Build a one-page matrix of permit types (NPDES, Title V, RCRA Part B, stormwater) listing who issues each, typical timelines, and what triggers a modification

Distinguish reporting thresholds and deadlines for EPCRA Tier II, TRI (Form R), and CERCLA release notification, and state the quantity basis for each

Explain how enforcement tools differ: administrative order, civil judicial action, criminal liability, and citizen suit, with the standard each requires

Apply the waste characterization decision path from generator status through listed and characteristic hazardous waste to a set of 12 practice scenarios

Calculate generator-size category thresholds and the associated accumulation time limits and container management requirements

Trace the RCRA cradle-to-grave chain including manifesting, land disposal restrictions, and the universal waste and used oil reliefs

Interpret a spill reporting scenario against CERCLA reportable quantities and CWA oil discharge rules to decide which agencies get notified and when

Describe the fate and transport mechanisms (advection, dispersion, sorption, volatilization, biodegradation) that govern a contaminant plume and match each to a sampling strategy

Compare remediation technologies (SVE, pump-and-treat, thermal, ISCO, bioremediation, permeable reactive barrier) by contaminant class, media, and site constraints

Explain the purpose and limits of Phase I and Phase II environmental site assessments and how results feed a remediation decision

Interpret common air dispersion and water quality modeling outputs well enough to critique assumptions in a case narrative

Integrate compliance knowledge with technical analysis by drafting the regulatory basis section of a corrective action plan for a contaminated site

Select sampling and analytical methods appropriate to the contaminant and medium, and state the holding time, preservation, and QA/QC requirements

Explain how data quality objectives and laboratory reporting limits affect a compliance determination

Identify where environmental science assumptions (background concentrations, natural attenuation rates) create regulatory risk

Apply the hierarchy of controls to at least six environmental remediation and industrial hygiene hazards and justify the chosen control for each

Explain exposure assessment fundamentals: routes of entry, dose-response, occupational exposure limits (PEL, TLV, REL), and the difference between them

Describe monitoring and medical surveillance requirements for noise, respiratory hazards, and chemical exposure, including when each is triggered

Outline the elements of a site-specific health and safety plan and the roles defined in a hazardous waste operations emergency response structure

Distinguish worker right-to-know and hazard communication obligations from process safety management requirements, and state which applies when

Explain confined space entry classifications, permit requirements, and atmospheric testing sequence

Describe respiratory protection program elements including fit testing, cartridge selection, and assigned protection factors

Apply incident investigation logic to determine root cause and the corrective action that prevents recurrence

Apply the core canons of a professional code of ethics (competence, honesty in reporting, avoidance of conflicts, confidentiality, public protection) to at least eight ambiguous scenarios

Distinguish the obligations owed to a client from those owed to the public and the regulator when they conflict, and state the disclosure standard

Explain the meaning and limits of practicing within one's area of competence and the duty to disclose uncertainty in technical findings

Identify situations requiring a conflict-of-interest disclosure or a refusal of engagement

Synthesize all four domains by working 60 mixed practice questions under timed conditions and reviewing every miss to its underlying knowledge gap

Re-drill your weakest two domains using the reference materials built in weeks 1-7 rather than new sources

Rehearse the ethics decision framework on five fresh scenarios to confirm transfer of the week 7 method

Build a one-page final review sheet of thresholds, deadlines, and standard citations most likely to be tested
