SLNC Registration study plan
SLNC Registration · Give each week a clear focus.
8 weeks · About 7 hours per week
Standards, Codes, and Regulations
Map the full regulatory hierarchy that governs septic/onsite wastewater system siting and design in your jurisdiction, from statute down to local health-department rule, and note where each layer adds requirements.
Build a one-page crosswalk of setback distances, vertical separation to limiting zone, and soil-treatment-area sizing rules, citing the specific code section for each number.
Define the permit pathway step by step (site evaluation, design submittal, construction permit, final approval) and identify which agency issues each approval.
List the ten code violations most commonly cited in your area and write the corrective action for each.
Your checkpoint
A two-page code crosswalk table with at least 25 cited requirements (setbacks, separation distances, sizing, permitting) and the exact section number for each.
Standards, Codes, and Regulations & Site Assessment and Planning
Interpret soil profile descriptions (texture, structure, consistence, redoximorphic features) and translate them into a determination of limiting zone depth.
Calculate soil loading rates from texture class and structure using the governing table, showing your work for at least five soil scenarios.
Sketch a site plan for a hypothetical lot that layers topography, slope class, drainage patterns, water table indicators, wells, and property lines.
Explain how slope, floodplain, and proximity to surface water each independently constrain system layout.
Your checkpoint
Five worked loading-rate calculations with soil descriptions and a labeled site-plan sketch showing all constraint layers.
Site Assessment and Planning
Perform a mock site evaluation on a real or photographed parcel, recording soil borings, depth to limiting zone, and slope readings in a field notebook format.
Determine a preliminary system type (conventional, alternative, or advanced treatment) from site constraints and justify the choice in writing.
Identify the reserve area requirement and demonstrate that the proposed layout satisfies it.
Draft a list of questions you would ask the regulator before design begins for a site with a shallow limiting zone.
Your checkpoint
A completed mock site assessment report (minimum 500 words) with boring log data, a constraint map, and a recommended system type with justification.
Design and Specification
Size a treatment tank, distribution network, and soil treatment area for a three-bedroom dwelling, showing each calculation step and the code basis.
Compare gravity, pressure distribution, and drip dispersal and state the site conditions that favor each.
Select materials and components (pipe, fittings, risers, effluent filters, pumps) against the applicable standard and write a short specification for each.
Produce a design drawing set with plan view, section, and profile showing elevations and slopes.
Your checkpoint
A complete design package for one dwelling: calculations, component specifications, and a three-sheet drawing set.
Design and Specification & Installation and Construction Practices
Write an installation sequence from excavation through final backfill, noting the inspection hold points at each stage.
Identify the construction practices that most often cause failures (compaction of infiltrative surfaces, smearing, improper bedding, inadequate slope) and state the prevention measure for each.
Explain safety requirements for excavation, confined-space entry into tanks, and equipment operation on site.
Draft a pre-construction checklist a contractor would use before breaking ground.
Your checkpoint
A staged installation checklist with at least eight inspection hold points and a parallel list of failure modes with prevention measures.
Installation and Construction Practices & Inspection, Testing, and Verification
Describe the tests performed at each inspection stage (soil verification, tank water test, distribution lateral verification, final grading) and the pass criteria for each.
Explain how to conduct and document a hydraulic load test and a dosing verification.
Identify signs of poor workmanship visible during a final inspection and how to record them objectively.
Outline the steps for commissioning a system and training the owner.
Your checkpoint
An inspection and testing protocol document covering at least six tests, each with procedure, acceptance criteria, and the record to be retained.
Inspection, Testing, and Verification & Documentation, Reporting, and Ethics
Assemble a complete project file: application, site evaluation, design, permits, inspection records, as-builts, and operation and maintenance information.
Write an inspection report that separates observed facts from professional opinion and states limitations clearly.
Analyze three ethical scenarios (pressure to approve deficient work, undisclosed site limitations, conflicts of interest) and state the correct course of action with reference to professional obligations.
Explain record retention and confidentiality expectations for site and client data.
Your checkpoint
A full sample project file with a written inspection report and a one-page ethics position statement on at least three scenarios.
Standards, Codes, and Regulations & Site Assessment and Planning & Design and Specification & Installation and Construction Practices & Inspection, Testing, and Verification & Documentation, Reporting, and Ethics
Complete two timed practice exams and score each domain separately to identify remaining weak areas.
Re-review the code crosswalk and loading-rate calculations, correcting any errors found in practice.
Recite from memory the key numeric thresholds (setbacks, separation distances, loading rates) without reference.
Write a one-page personal summary of the five concepts you are most likely to confuse on exam day and the distinction for each.
Your checkpoint
Two scored practice exams with a domain-by-domain error log and a final one-page concept-distinction summary.
Milestones
Week 2: Can state the governing code section for any setback or separation distance asked, and complete a loading-rate calculation from a soil description without notes.
Week 4: Produce a full design package for a single dwelling in under three hours with calculations that reconcile to the code tables.
Week 6: Explain every inspection hold point and its pass criteria, and identify at least five visible workmanship defects from a description alone.
Week 8: Score at least 80 percent on both timed practice exams with no domain below 70 percent.
