What igst.com is, in plain terms

igst.com is the domain used by Ground Service Technology, Inc. (often written as iGST or GST), a California-based contractor and consulting firm focused on erosion control and stormwater compliance for construction and industrial sites. The company positions itself as a “full service” provider that can handle planning, documentation, inspections, and field implementation work tied to stormwater permits. Their public-facing pages also list two offices (Escondido in Southern California and Fresno in Northern California), which hints at the footprint they’re set up to serve.

If you landed on igst.com expecting a tax acronym (IGST in other contexts) or something software-related, this one is more practical: keeping job sites compliant so they don’t get hit with enforcement, stop-work issues, or the slow grind of rework after a failed inspection.

The problem they’re built around: construction stormwater rules are not optional

Stormwater compliance is one of those areas where people only realize how serious it is when a project is already underway and the paperwork doesn’t match the field conditions.

At the federal level in the U.S., stormwater discharges from construction activities are regulated under the Clean Water Act via the NPDES program. EPA guidance is blunt about the trigger: if you disturb 1 acre or more (or less than 1 acre but part of a larger common plan that totals 1+ acres), you generally need permit coverage.

A big part of that coverage is the SWPPP (Stormwater Pollution Prevention Plan). EPA maintains SWPPP resources and templates because, in practice, a SWPPP is where the site-specific controls, inspection routines, and responsibilities get documented.

Now layer on state rules. In California, the State Water Resources Control Board’s Construction General Permit has its own requirements and (importantly) expects qualified stormwater professionals for developing and implementing SWPPPs. California also formalizes training and qualifications through programs administered by CASQA for roles like QSD/QSP (construction) and QISP (industrial).

This regulatory backdrop is basically the market iGST sits in: translating permit requirements into a job site that actually passes scrutiny.

What iGST says it does: services that connect paperwork to field reality

On the iGST/GST site content that is accessible publicly (mirrored at erosioncontroller.com), the service list is pretty direct and oriented around the usual compliance pain points:

  • SWPPP services (design, filing, implementation, and inspections).
  • Dust control / soil stabilization, described as using biodegradable and environmentally friendly products.
  • Filtration and dewatering, specifically filtering sediment-laden trench or basin water using a bag process that retains sediment while allowing water to seep out.
  • Hydroseeding, described as spraying a slurry (seed, tackifier, mulch, fertilizer) to stabilize bare ground while vegetation establishes.
  • BMP installations like sand/gravel bags, silt fence, fiber rolls, storm drain inlet protection, and related measures.
  • Street sweeping for construction sites (not glamorous, but it matters when sediment and track-out are part of your risk profile).

Their homepage also calls out “Construction & Industrial SWPPP / QISP” as a top-line category, which implies they position themselves across both construction permit work and industrial stormwater programs.

If you’ve dealt with stormwater compliance before, you’ll recognize why bundling these matters: a SWPPP that looks fine on paper won’t help much if BMPs aren’t installed correctly, maintained, documented, and adjusted after rain events or site changes.

Who typically uses a firm like this

Based on the company’s own description, they work with a mix that includes large enterprises and public-sector entities, plus small and mid-sized contractors and engineering firms.

They also have a “Municipal” page that describes expanding beyond erosion control into inspection, monitoring, and preparation of SWPPP documents, and then further into professional services like civil engineering, landscape design, municipal planning, and legal services. It also mentions supporting government agencies with plan and permit review, entitlement/conditions of approval support, staff augmentation, and construction management/inspection services.

So the customer types usually fall into three buckets:

  1. Operators/owners who hold the permit coverage and want someone to run the compliance machine day-to-day.
  2. General contractors and subs who need erosion control and BMP work done correctly and documented.
  3. Public agencies that need extra staff capacity or specialized expertise for reviews and inspections.

A realistic workflow: what “full service” often looks like on a live job

Even without seeing a specific scope of work for your project, stormwater compliance work tends to follow a predictable pattern:

  1. Project intake and site understanding
    You define the disturbed area, schedule, drainage patterns, discharge points, sensitive receptors, and what activities drive pollutant risk (grading, stockpiles, concrete work, fueling, etc.). This is where SWPPP strategy begins.

  2. SWPPP development and permit filing support
    The SWPPP is drafted (or updated), responsibilities are assigned, and documentation is aligned with the permit you’re under. EPA’s SWPPP guidance makes the point that SWPPPs must be site-specific and match applicable permit requirements, not generic boilerplate.

  3. BMP installation and stabilization work
    This is the physical stuff: perimeter controls, inlet protection, fiber rolls, silt fence, stabilized entrances, dust suppression, temporary or permanent stabilization (including hydroseeding), and dewatering/filtration setups when you’re moving trench water or basin water.

  4. Inspections, reporting, and corrective actions
    Inspections are where projects win or lose. You inspect, document, fix issues, and track the fixes. In California, that often intersects with the requirement to use qualified professionals under the Construction General Permit framework.

  5. Closeout and record retention
    When the disturbed area is stabilized and the permit obligations are satisfied, you close out appropriately and keep records in case questions come later.

Firms like iGST position themselves as covering that whole chain, which is usually the part owners care about: fewer gaps between “plan,” “field,” and “proof.”

What to check before you rely on any stormwater compliance vendor

If you’re evaluating iGST (or any similar provider), these are the practical checks that actually reduce risk:

  • Credentials and fit to your permit: If you’re in California, confirm the role requirements that apply (QSD/QSP for construction, QISP for industrial) and whether the individuals assigned meet them. California’s Water Boards and CASQA spell out that these qualifications exist to support permit compliance.
  • Inspection documentation quality: You want consistent reports, clear corrective action logs, photos when needed, and dates/times that match permit requirements.
  • Field capacity: If they say they do installations and maintenance, verify they can mobilize when weather changes or when the site shifts phases fast.
  • Regulator familiarity: Not in a “we know someone” way, but in the boring way: they understand how enforcement tends to happen, what inspectors focus on, and what documentation gets questioned.
  • Insurance and accountability: iGST explicitly mentions their insurance meeting or exceeding requirements, which is something you still want to confirm contractually for your specific project.

Also, remember the uncomfortable truth: outsourcing the work doesn’t outsource legal responsibility. The permittee/operator is still on the hook, which is exactly why the paper trail matters so much.

Key takeaways

  • igst.com is associated with Ground Service Technology, Inc. (iGST/GST), a California firm focused on erosion control and stormwater compliance services.
  • Their public service list spans SWPPP design/filing/implementation/inspections plus field services like BMP installation, hydroseeding, dewatering filtration, dust control, and street sweeping.
  • Stormwater rules are driven by NPDES permitting; EPA notes construction disturbing 1+ acre (or part of a larger plan) generally requires permit coverage and SWPPP controls.
  • In California, construction and industrial stormwater programs rely on defined qualifications (QSD/QSP, QISP) administered through CASQA programs tied to Water Board requirements.
  • The value of a “full service” provider is reducing the gap between what the SWPPP says and what the site is actually doing, with documentation that holds up later.

FAQ

Is iGST the same thing as “IGST” tax?

No. igst.com (in this context) points to Ground Service Technology, Inc., which is positioned around stormwater, erosion control, and environmental compliance services, not a tax system.

When do I need a SWPPP?

Commonly, when your project needs stormwater permit coverage. EPA states that construction disturbing 1 acre or more (or part of a larger common plan that disturbs 1+ acres) generally requires a Clean Water Act permit for stormwater discharges, and SWPPPs are a core requirement under construction stormwater permits.

What does “SWPPP implementation” mean in practice?

It usually means installing the required BMPs, maintaining them, inspecting them on schedule and after certain events, documenting conditions, and completing corrective actions when something fails or site conditions change.

What is QISP, and why would a contractor mention it?

QISP stands for Qualified Industrial Storm Water Practitioner in California’s industrial stormwater program context. The California Water Boards describe it as a training/certification track administered by CASQA for the Industrial General Permit.

Do firms like iGST handle municipal work too?

Their municipal service description says they expanded into inspection, monitoring, SWPPP documentation, and broader professional services that can support agencies (plan/permitting review, entitlements, staff augmentation, and construction management/inspection).

What should I prepare before contacting a stormwater compliance provider?

Have your site location, estimated disturbed acreage, project schedule/phasing, receiving waters info if known, whether you’re under a construction permit or industrial permit, and any prior inspection reports or notices. If you already have a SWPPP, share the latest version plus site maps and any recent change orders that affect drainage or soil disturbance.

Where is iGST located?

The company’s site lists an office in Escondido, California and another in Fresno, California.
