STORMWATER VISUAL AND ANALYTICAL SAMPLING (MSGP & MS4) FOR THE PORT OF HOUSTON AUTHORITY

houston, Texas

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.

MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) ANNUAL REPORT FOR THE PORT OF HOUSTON AUTHORITY

houston, Texas

SNM2R completed the 2016, 2017, 2018, 2019, and 2020 MS4 Annual Reports for the Port of Houston Authority as a subcontractor to Atkins North America, Spirit Environmental, and Terra Nova Consulting, under the current Port of Houston Authority Water Quality Consultation Contract.

Port Houston (PHA) currently holds a Texas Pollutant Discharge Elimination System (TPDES) municipal separate storm sewer system (MS4) permit to discharge pollutants associated with stormwater to surface waters of the State. Under Part IV.A of the permit, the PHA must prepare an annual system wide MS4 report no later than March 31 of each year.

Each Spring, SNM2R prepares an annual report for the PHA to be submitted to the Texas Commission on Environmental Quality (TCEQ). The MS4 Annual Report includes the status of implementing the Port’s Stormwater Management Plan (SWMP), an assessment of the appropriateness of the identified BMPs, the measurable goals of each of the required program components, and an evaluation of the success of the implementation of the measurable goals. It also includes any proposed changes to the SWMP and a summary and analysis of the data collected as a condition of the permit or as a component of the SWMP.

Based on the information gathered, SNM2R generated annual report for each 2016, 2017, 2018, 2019 and 2020 that summarized the number and nature of enforcement actions, inspections, and public education programs including Identification of water quality improvements or degradation, and the success of the SWMP at reducing the discharge of pollutants to the maximum extent practicable.

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.
