Regulatory Explorer¶
The Regulatory Explorer is the rule-first entry point for Green Guides. It keeps the governing N.J.A.C. 7:8 standards separated by function so the later BMP, constraints, and workflow pages do not collapse recharge, runoff quality, runoff quantity, and volumetric reduction into one undifferentiated narrative.
Structured citation evidence for this page lives in the sibling claim manifest.
Module Scope¶
The live source set anchors this module to the parts of N.J.A.C. 7:8 that change project obligations at the site scale:
| Topic | Governing focus in the live source set | Why it matters downstream |
|---|---|---|
| Major Development Definition | N.J.A.C. 7:8-1.2 definition triggers |
Determines whether the project enters the full Subchapter 5 standards |
| Green Infrastructure Requirement | N.J.A.C. 7:8-5.3 and Table 5 logic |
Controls which BMP tables can be used for each standard |
| Groundwater Recharge Rules | N.J.A.C. 7:8-5.4 and 7:8-5.7 |
Sets the recharge target, exemptions, and calculation assumptions |
| Water Quality Design Storm | N.J.A.C. 7:8-5.5 |
Anchors runoff-quality sizing and the TSS standard |
| Stormwater Quantity Control | N.J.A.C. 7:8-5.6(b) |
Governs the 2-, 10-, and 100-year quantity framework |
| Volumetric Reduction Credit | N.J.A.C. 7:8-5.6(d) |
Adds the 2026 retention-based compliance path |
How To Use This Module¶
The safest way to read the rules in this project is:
- Start with the triggering question in Major Development Definition.
- Split the applicable standards into separate lanes: GI table logic, recharge, runoff quality, runoff quantity, and volumetric reduction.
- Carry those distinct rule obligations into the Engineering Constraints and Design Workflow modules.
That sequence is deliberate. The source corpus repeatedly shows that design mistakes happen when the project team assumes one rule summary can stand in for all of Subchapter 5.
2026 Focus Without Rule Drift¶
The live source set supports a narrower 2026 summary than the older narrative pages:
- volumetric reduction is a codified subsection at
N.J.A.C. 7:8-5.6(d) - the Water Quality Design Storm itself did not change
- the GI definition still lives in
N.J.A.C. 7:8-1.2 - table-based BMP selection still turns on
N.J.A.C. 7:8-5.3
This module therefore treats volumetric reduction as an added compliance path, not as a replacement for the base definitions, recharge standard, or water-quality storm.
