SNM2R has successfully been conducting stormwater visual and analytical monitoring for the Port of Houston Authority since the October of 2016 to date as a subcontractor to Atkins North America, Spirit Environmental, and Terra Nova Consulting under the current Port of Houston Authority Water Quality Consultation Contract. 

The Port of Houston Authority requires quarterly visual screening activities and analytical monitoring activities in compliance with the Texas Discharge Pollutant Elimination System (TPDES) multi-sector general permit (MSGP). Additionally, PHA’s Municipal Separate Storm Sewer System (MS4) Permit requires annual analytical stormwater sampling.

SNM2R conducts MSGP quarterly-visual screening and annual/semi-annual analytical monitoring activities for seven representative outfalls at three PHA facilities. MSGP monitoring activities include visual screening, benchmark sampling, and numeric effluent limit sampling.  Visual monitoring is required to be conducted once every quarter. Sector specific Benchmark sampling is required semi-annually, while numeric effluent limit sampling is required annually. Additionally, SNM2R conducts MS4 annual analytical monitoring activities for eleven representative outfalls at four PHA facilities. MS4 monitoring activities are required annually.

SNM2R monitors storms on qualifying events, which are identified as storms having measurable runoff and a preceding 72-hour antecedent dry period. SNM2R monitors meteorological conditions and storm fronts in order to anticipate qualified storm events. During the first 30 minutes of a measurable rain event, a sample is collected from the outfall.  If it is not possible to sample in the first 30 minutes, a sample is completed in the first hour, with the reason documented. Field forms are submitted to the client and samples are delivered to the laboratory for analysis.

ILLICIT DISCHARGE DETERMINATION & ELIMINATION (IDDE - MS4) FOR THE PORT OF HOUSTON AUTHORITY

houston, Texas

SNM2R has successfully been conducting Illicit Discharge Determination and Elimination Screening and Monitoring for the Port of Houston Authority since the October of 2018 to date as a subcontractor to Spirit Environmental and Terra Nova under the current Port of Houston Authority Water Quality Consultation Contract.

The Port of Houston Authority requires Annual Dry Weather Illicit Discharge Determination and Elimination (IDDE) screening and illicit discharge sampling in compliance with the requirements of its Municipal Separate Storm Sewer System (MS4) Permit and the commitments of its Storm Water Management Plan (SWMP).

The current MS4 permit was issued on February 14, 2017 and will expire in 2022. The IDDE sampling is conducted at about 30 Outfalls per year. SNM2R performs field screening on these outfalls to inspect for the presence or evidence of inappropriate non-stormwater discharges known as “illicit discharges.” The level of trash and/or debris is noted as part of the inspection. Field screening is performed during dry weather conditions with an antecedent dry period of at least 72-hours (no more than 0.1-inch of measurable rainfall in that period). SNM2R makes every attempt to access outfalls to be screened from the land. Where necessary, SNM2R performs a portion of the screening by boat and obtains permission from the appropriate agencies (PHA Security, PHA Environmental, and other entities/PHA Departments as recommended by the PHA), to access the outfall locations through navigable waters of the Houston Ship Channel

For all outfalls that are flowing during this dry weather screening event, SNM2R collects samples using a field stormwater sampling kit. SNM2R uses a LaMotte Storm Drain Kit as specified in the Port’s IDDE Procedures Manual. Stormwater is screened for total residual chlorine, phenols, total copper, detergents, pH, and temperature and then sent to the laboratory for further analysis of needed.

TxDOT STORMWATER ADVISORY TEAM (SWAT) VISIT ANALYSIS

MULTI DISTRICT​

TxDOT conducts internal inspections called Stormwater Advisory Team (SWAT) visits to provide an internal compliance review for provisions related to the Texas Pollutant Discharge Elimination System (TPDES) Construction General Permit (CGP) TXR150000 administered by the Texas Commission on Environmental Quality (TCEQ) and the environmental issues, permits, and commitments (EPICS) identified during the environmental clearance process. These projects are reviewed using the “SWAT Visit Checklist” and the “SWAT SWP3 Checklist”. Results are provided to the District offices in a final report.

SNM2R assisted TxDOT with compiling the SWAT visit data.SNM2R reviewed  the SWAT, and SWP3 checklists, and final reports for completeness and checked them for consistency in data entries and entry criteria. Inconsistencies and data gaps identified will be brought to the attention of Prime Consultant  – Atkins.

SNM2R then used a spreadsheet template to enter field collected SWAT and SWP3 data as well as converted field entries into formats suitable for the descriptive analysis. SWAT checklist criteria was grouped by SNM2R into four main categories: CGP/Stormwater Resources, Change Orders and Notices of Change, Environmental Permits, Issues and Commitments (EPICs) and Additional Comments. The CGP/Stormwater resources were broken down into eight sub-categories (e.g., Posting Requirements and EMS & SWP3 Binder) and the EPICs category were broken down into the six EPIC sheet section categories. Change Orders and Notices of Change and Additional Comments criteria were evaluated based on the individual field entries. SWP3 checklist criteria will evaluated based on the individual field entries without any subcategories. 

SNM2R reviewed the high-level items noted in the final reports to ensure that the GSMs, CTRs and DARs were captured under the SWAT and/or SWP3 Checklist analysis.

SWAT and SWP3 checklist analysis results were presented by SNM2R under one of four options: Not Evaluated (NE), Not Applicable (NA), Compliant (C) and Noncompliant (NC).

SNM2R provided spreadsheets (one per district) to include the collected field data and required analysis entries. Tabs were created for each project. An overall spreadsheet for combined SWAT and SWP3 analysis data was created.
