Suffolk County I/A OWTS Designer Renewal: NY PE Prereq and the Article 19 Continuing-Ed Requirement

By The Complos Team. Last reviewed 2026-05-14.

TL;DR. What it actually takes to keep your SCDHS I/A OWTS designer registration active: NY PE in good standing, $175–$275 re-registration, and 4-hour annual Article 19 CE.

Your SCDHS designer registration shows up in the same drawer as your NY PE seal and your homeowner-grant submittal templates. You've designed 40-plus I/A systems in Suffolk in the last three years, mostly Hydro-Action and Norweco units in the Save-Our-Lagoons grant zone. The annual re-registration window is open and SCDHS just emailed about an Article 19 continuing-ed audit they're piloting.

This is the renewal article for the working I/A OWTS designer in Suffolk County — the engineer who depends on the SCDHS registration to get plans across the desk on Yaphank Avenue, not the homeowner trying to figure out what their designer is doing.

The Two Credentials You're Actually Renewing

There is no single "Suffolk I/A designer" license. There are two stacked credentials, and both have to be active for you to file a design under Article 19 of the Suffolk County Sanitary Code:

1. New York State Professional Engineer (PE) license — issued by the NY State Education Department (SED). 3-year cycle. 36 contact hours of approved continuing education per cycle. Without an active PE, the SCDHS registration is meaningless because Article 19 §760-1607 requires designs be sealed by a licensed PE.
2. SCDHS I/A OWTS Designer Registration — issued by the Suffolk County Department of Health Services, Office of Wastewater Management. Annual renewal. Filing fee, recent design history, and Article 19 CE all required.

The fastest way to lose Suffolk filing privileges is to let the PE lapse and assume the SCDHS registration buys you any cover. It doesn't. SCDHS verifies PE status with SED on each design submittal.

SCDHS Annual Re-Registration: What It Costs

The 2026 SCDHS designer re-registration fee schedule, as published on the OWM portal:

• I/A OWTS designer (annual re-registration): $175 base.
• I/A OWTS designer + installer combined registration: $275 (only available where the designer is also a licensed Suffolk installer; rare combo).
• Late re-registration surcharge (within 60 days of expiration): additional $75.
• Re-registration after 60-day lapse: full re-application required, treated as a new applicant ($250 application fee plus $175 registration). The new-applicant track adds a 6-to-10-week SCDHS review window before you can file designs again.

The $175 base is unchanged from 2024, but the 60-day cliff is firmer than it used to be. SCDHS started rejecting late re-registration applications outright in 2025 once the 60-day window closed; the workaround that used to work — a friendly call to the Office of Wastewater Management — doesn't anymore.

The 4-Hour Annual Article 19 CE Requirement

This is the new piece for 2026 and the one most working designers haven't internalized. SCDHS, under the 2024 amendment to the OWM registration program, requires registered I/A OWTS designers to complete at least 4 hours of Article 19-specific continuing education each calendar year. The 4 hours are in addition to whatever you complete toward your NY PE.

What "Article 19-specific" means in practice:

• Updates to §760-1607 (I/A OWTS standards) and §760-1610 (groundwater protection setbacks).
• SCDHS-issued technical bulletins on approved treatment-unit performance standards.
• Hydraulic-loading methodology updates (Suffolk uses a more conservative loading rate than NYSDEC for I/A systems in nitrogen-priority watersheds).
• The pre-treatment-unit-to-dispersal-field interface details that Suffolk plan reviewers reject for most often.

Approved providers for the 4-hour Article 19 requirement, as of the 2026 OWM list:

• SCDHS Office of Wastewater Management quarterly designer roundtables — free, typically 2 hours each, the easiest 4 hours to bank.
• Long Island Section ASCE I/A OWTS technical sessions — paid, $75 to $150 for 2 to 4 hours.
• Cornell Local Roads / Cornell Water Resources Institute Suffolk-track sessions (when offered) — typically free or low-cost through extension.
• Stony Brook University Center for Clean Water Technology — research-and-policy briefings, usually 1 to 2 hours, free.

The audit: SCDHS announced they would audit roughly 5 percent of registered designers each year for Article 19 CE compliance starting in 2025. The audit pull asks for certificates and the agenda of each course. Don't assume informal site visits with SCDHS staff count as CE; they don't.

NY PE Side of the Stack — Just Enough Detail

Your NY PE renewal is the larger story (36 hours over 3 years, separate article) but the Suffolk-specific anchors:

• Of the 36 PE contact hours, at least 1 hour every 3 years must be on professional ethics. NY SED enforces this strictly.
• No more than 18 of the 36 hours can be self-study/home-study. The cap is similar to FDEP's pattern, with the same trap — designers who default to convenience cap themselves at the wrong end of the cycle.
• The NY PE renewal fee in 2026 is $175 to $200, depending on whether you renew online or paper.

A renewal-management note: align your PE 3-year cycle and your SCDHS annual cycle so that the PE renewal date sits well inside an SCDHS year. If your PE expires in March and your SCDHS registration expires in February, you have a 30-day overlap where any PE-renewal hiccup blocks SCDHS. Ask SED for an early-renewal slot if your dates collide.

What Gets Rejected at SCDHS Plan Review

SCDHS rejects roughly 12 percent of Article 19 I/A designs in their first review. The rejection patterns I see are not exotic; they're the same handful of issues:

• Pre-treatment unit too close to property line. Suffolk's I/A pre-treatment setback is more aggressive than the NYSDEC residential standard. Designers using a NYSDEC template miss this constantly.
• Hydraulic loading rate too generous. Suffolk uses a more conservative LR for I/A dispersal in nitrogen-priority groundwater management zones. Designs at NYSDEC's loading rate get bounced.
• Approved-product list mismatch. Suffolk maintains its own approved-treatment-unit list, separate from NYSDEC. A unit on NYSDEC's list is not necessarily on Suffolk's. Verify the model number and the approval date — units get added and removed.
• Missing groundwater monitoring well plan for systems within designated SGPAs (Special Groundwater Protection Areas). The MW plan is a separate submittal requirement under Article 19 §760-1611 that out-of-county designers routinely miss.
