Registered Environmental Protection Engineer study plan

Registered Environmental Protection Engineer · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Water Pollution Control and Wastewater Treatment & Environmental Laws, Regulations, and Standards

  • Map the wastewater domain into unit-process groups (pretreatment, primary, biological, tertiary, disinfection, sludge) and assign each a study slot in your calendar

  • Compute design values for an activated sludge system: F/M ratio, solids retention time, hydraulic retention time, and recycle ratio, showing units at each step

  • Read the Clean Water Act framework and list which permit type (NPDES, pretreatment, stormwater) governs each of five discharge scenarios

  • Build a one-page formula sheet for flow conversion, loading (kg/d), and removal efficiency that you will reuse all eight weeks

Your checkpoint

A 15-page personal reference summarizing biological treatment design equations plus a table matching five discharge scenarios to the correct CWA permit mechanism

Week 2

Water Pollution Control and Wastewater Treatment

  • Solve six numerical problems covering BOD/COD kinetics, nitrification-denitrification stoichiometry, and oxygen demand

  • Compare activated sludge, trickling filter, MBBR, and SBR configurations on footprint, loading tolerance, and operational complexity

  • Diagnose three classic failure modes (bulking, foaming, poor settling) and state the corrective operational action for each

  • Size a secondary clarifier using solids loading rate and hydraulic loading rate, and check surface overflow rate

Your checkpoint

A worked problem set of six wastewater calculations with full unit tracking and a two-page troubleshooting matrix linking sludge symptoms to operational causes

Week 3

Air Pollution Control and Air Quality Management & Environmental Laws, Regulations, and Standards

  • Convert between ppm, mg/m3, and ug/m3 at reference conditions and correct volumetric flow to standard temperature and pressure

  • Apply Gaussian plume dispersion concepts qualitatively to explain how stack height, stability class, and terrain affect downwind concentration

  • Match criteria pollutants and their health effects to the National Ambient Air Quality Standards structure (primary, secondary, averaging times)

  • Trace how a Prevention of Significant Deterioration or nonattainment New Source Review applicability determination is triggered by a project change

Your checkpoint

An air-quality standards reference card plus three solved dispersion and unit-conversion exercises showing corrected standard-condition results

Week 4

Air Pollution Control and Air Quality Management & Solid Waste and Hazardous Waste Management

  • Select and size control equipment for particulate matter (cyclone, baghouse, ESP, scrubber) and justify the choice for three given gas streams

  • Explain the chemistry and reagent handling for acid gas scrubbing and for NOx control via selective catalytic and non-catalytic reduction

  • Classify solid waste streams and identify which regulatory category (municipal, hazardous, universal, e-waste) applies to five examples

  • Apply the hazardous waste characteristics (ignitability, corrosivity, reactivity, toxicity) and the generator-size categories to determine accumulation limits

Your checkpoint

A control-device selection decision table with sizing calculations for two cases, plus a hazardous waste determination worksheet completed for five waste streams

Week 5

Environmental Impact Assessment and Permitting & Environmental Laws, Regulations, and Standards

  • Outline the required contents of an environmental impact statement and identify which statute drives each element

  • Distinguish categorical exclusion, environmental assessment, and full EIS pathways and state the decision criteria for each

  • Draft a public participation and scoping sequence with realistic timelines for a hypothetical project

  • Identify which federal permits (air, water, wetlands, endangered species) a described project would need and in what order they typically issue

Your checkpoint

A complete EIS outline with annotated statutory basis plus a permit matrix for one hypothetical project listing each required authorization and its sequence

Week 6

Environmental Monitoring, Sampling, and Analysis & Environmental Laws, Regulations, and Standards

  • Design a sampling plan for a wastewater and an ambient air monitoring objective, specifying sample count, container, preservation, and holding time

  • Calculate detection limits, precision, and bias from a small replicate and spike dataset

  • Explain chain-of-custody requirements and identify where a described field record would fail defensibility

  • Differentiate quality assurance from quality control and place each element in a data quality objective framework

Your checkpoint

Two complete sampling and analysis plans (water and air) with quality control tables and a worked detection-limit and precision calculation

Week 7

Soil and Groundwater Contamination and Remediation & Noise, Vibration, and Other Physical Pollution Control

  • Outline a site investigation sequence from records review through subsurface characterization and identify the data each phase produces

  • Compare pump-and-treat, soil vapor extraction, in-situ chemical oxidation, and monitored natural attenuation on applicability and timeframe

  • Apply the fundamentals of sound pressure level, A-weighting, and distance attenuation to compute a downwind level from a point source

  • Identify mitigation measures for construction and transportation noise and state which metric (Leq, Ldn) is typically used for each context

Your checkpoint

A remediation technology comparison table with a sample conceptual site model plus four solved noise calculation problems including a barrier insertion loss estimate

Week 8

Environmental Laws, Regulations, and Standards & Water Pollution Control and Wastewater Treatment & Air Pollution Control and Air Quality Management & Solid Waste and Hazardous Waste Management & Environmental Impact Assessment and Permitting & Environmental Monitoring, Sampling, and Analysis & Soil and Groundwater Contamination and Remediation & Noise, Vibration, and Other Physical Pollution Control

  • Take two full-length timed practice exams and record per-domain accuracy to identify remaining weak areas

  • Re-derive the ten formulas you most often missed and write a one-line trigger cue for each

  • Review every missed item and write the underlying rule, not just the corrected answer

  • Rehearse the exam-day time allocation per question and confirm your reference and calculator policy

Your checkpoint

A scored practice exam log with per-domain accuracy percentages and a one-page final review sheet of rules and trigger cues for recurring errors

Milestones

Week 2: You can complete a full activated sludge sizing calculation from scratch, with correct units, in under 12 minutes without notes.

Week 4: You score at least 70 percent on a self-made 30-question quiz drawn from Domains 2 and 3, and can justify each control-device choice in writing.

Week 6: You correctly classify all five hazardous waste examples and produce a defensible sampling plan without referring to a template.

Week 8: Practice exam scores reach at least 75 percent overall with no single domain below 60 percent accuracy.
