When a Virginia Project Needs an Individual VSMP Permit

VAR10: the default general permit

The VAR10 General VPDES Permit for Discharges of Stormwater from Construction Activities is the Virginia DEQ's standard coverage mechanism. It applies to construction operators of projects disturbing one acre or more, or less than one acre if part of a common plan of development or sale (CPOD) cumulatively disturbing one acre or more. Single-family residential construction under one acre uses a simplified SWPPP pathway.

Coverage under VAR10 is obtained by filing a Registration Statement with DEQ and having a Stormwater Pollution Prevention Plan (SWPPP) in place. Review timelines are typically weeks, handled through VSMP authorities (locality-run in many cases, DEQ-direct in others). Standard workflow for most commercial and residential development in the Commonwealth. Primary source: deq.virginia.gov/water/stormwater/stormwater-construction.

When VAR10 doesn't apply — the main triggers

Several categories of project are ineligible for VAR10 or are steered to Individual VPDES/VSMP by DEQ discretion:

1. Discharge to impaired waters or waters with TMDL constraints

Projects whose construction stormwater discharges to surface waters classified as impaired (on Virginia's 303(d) list) or subject to a Total Maximum Daily Load (TMDL) for pollutants the site could contribute may require enhanced controls beyond what VAR10 authorizes. Depending on the specific impairment and TMDL status, DEQ may condition VAR10 coverage with additional requirements or direct the project to Individual VPDES/VSMP review.

Identify the receiving water's 303(d) status and applicable TMDLs during pre-design. DEQ's water quality assessment database is the authoritative source.

2. Threatened and endangered species habitat

Projects located in areas with known federally-listed or state-listed threatened or endangered species habitat may require Individual permit review for species-specific protection measures. VA Department of Wildlife Resources coordination is typically part of the intake; a habitat hit can shift the permit path.

3. Discharge to exceptional waters or sensitive designations

Virginia's water classification system includes designations requiring additional protection — exceptional waters, public water supply intakes, and similar. Discharges to these waters trigger enhanced analysis and may route the project to Individual VPDES/VSMP where site-specific conditions are needed.

4. Project already under an individual permit

If the site or operation is already covered by an individual VPDES permit (industrial, municipal, or facility), construction stormwater cannot be layered under VAR10 in a way that commingles discharges. The existing individual permit framework takes over.

5. Large scale or complex hydrology

Projects above typical scale thresholds, unusually complex drainage, or industrial installations with site-specific pollutant loading concerns may be directed to Individual VPDES/VSMP by DEQ to accommodate site-specific permit conditions that VAR10's general terms can't carry.

6. Chesapeake Bay Preservation Act overlay

Projects within Chesapeake Bay Preservation Areas (CBPAs) generally remain under VAR10 but face additional local VSMP authority scrutiny. Some CBPA projects with unusual site conditions are steered to Individual VPDES/VSMP for site-specific conditions that VAR10 can't accommodate. Coordinate with the local VSMP authority early.

Why the timeline difference matters

VAR10 Registration Statement review is typically weeks through the local VSMP authority. Individual VPDES/VSMP review is months — often 6+ months depending on complexity, public participation, and reviewer workload. The schedule and cost implications:

• Schedule. Construction start dates push out if Individual applies. Mobilization, material orders, and financing draws key off permit issuance.
• Design depth. Individual permits require more rigorous technical documentation — site-specific hydrology, pollutant loading analysis, enhanced BMP sizing, alternative analyses where relevant.
• Public participation. Individual permits include public notice and potential hearing, adding time and political risk.
• Permit conditions. Individual permits can carry site-specific monitoring, reporting, and adaptive management conditions increasing operational compliance effort across the project duration.
• Fees. Individual permit fees are higher than VAR10 Registration Statement fees.

Catching the VAR10 / Individual question early

The practical steps for identifying which permit applies before design effort is committed:

1. Identify the receiving water. Map the site's drainage to downstream surface waters. Check DEQ's water quality assessment database for impaired status and TMDL constraints.
2. Check for threatened/endangered species hits. VA Department of Wildlife Resources review and USFWS IPaC review flag species concerns.
3. Verify Chesapeake Bay Preservation Area designation. CBPA status affects local VSMP authority requirements beyond the VAR10/Individual question.
4. Confirm CPOD scope. If the project is part of a larger common plan of development or sale, cumulative acreage determines applicability even if your sub-phase is under an acre.
5. Talk to the VSMP authority. Most localities administer VSMP on DEQ's behalf. The VSMP authority sees routine Registration Statements and quickly flags eligibility concerns. Free and high-value.
6. Document your eligibility determination. Written record of why VAR10 was appropriate protects against future enforcement disputes.

If you're already mid-design and Individual applies

The rework is non-trivial but manageable. Much of the E&S and stormwater management plan work done for VAR10 transfers; the hydrology and BMP sizing carry forward with additional technical depth. The schedule slip is the major cost.

• Coordinate with DEQ regional office on the Individual application scope early.
• Expand technical documentation to meet Individual expectations — site-specific hydrology, enhanced BMP sizing, water quality analysis.
• Plan for public notice and potential hearing window.
• Communicate schedule changes to owner and construction team immediately; don't let mobilization happen before Individual issuance.

How this compares to PA PAG-02 vs Individual NPDES

Virginia and Pennsylvania run structurally parallel systems under the federal NPDES framework, with state-specific implementation. Key alignments and differences:

• Size threshold. Both use 1 acre (or CPOD aggregate to 1 acre) for general-permit applicability.
• Impaired waters trigger. Both states route some impaired-water-discharge projects to individual permits; specifics differ. See our PA PAG-02 vs Individual NPDES essay for the Pennsylvania side.
• HQ/EV (PA) vs. Exceptional/CBPA (VA). Both states have watershed-protection overlays that can affect permit path, with different classification systems.
• Administration. PA uses county conservation districts for general permit intake; VA uses local VSMP authorities (often localities, sometimes DEQ-direct).
• Chesapeake Bay. VA has Chesapeake Bay Preservation Act overlay with local VSMP authority scrutiny; PA has Chesapeake Bay Tributary Strategy Watershed considerations but not an analogous state-statutory overlay.

What to do with this

For every VA construction project: identify receiving water classification and run habitat/species review as pre-design activities. They take hours and protect the schedule against a late VAR10/Individual flip.

For projects discharging to impaired waters, in species habitat, in sensitive CBPA areas, or above usual scale: plan for Individual timeline from the start rather than hoping VAR10 applies.

For multi-state contractors: the VA and PA systems rhyme but don't match. Don't assume PAG-02 eligibility patterns transfer to VAR10.
