Course Length: 60 minutes

Purpose and Background

The Guideline for Certification of Stormwater BMPs has two primary purposes 1) Development of a protocol for assessing the efficiency of MTDs (Manufactured Treated Devices) used for physical separation of nondissolved solids from stormwater runoff, including the assessment of scouring of settled particles under high flow conditions. The removal of trash, leaves, and hydrocarbons are not included in this protocol. 2) To aid regulators in establishing certification programs for MTDs with a broad set of analytical tools that could be adapted for local regulatory agency needs.

The following critical components of the Guidelines are addressed in this webinar: Laboratory Testing, Scaling Relations, Field Testing, Data Analysis and Performance Evaluation, Data Reporting, Inspection and Maintenance, and Verification and Certification Programs and Processes.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Recognize three distinctively different and essential skill sets necessary to monitor and evaluate MTDs.
• Explain why laboratory testing results and field testing of MTDs are not comparable.
• Explain why Suspended Solids Concentration sampling gives better results than Total Suspended Solids in field testing.
• Recognize recommended MTD laboratory testing method.
• Apply proper ways to monitor MTD performance in a lab and in the field.
• Recognize the difference between concentration and mass loading based monitoring.
• List different methods utilized in different U.S. regions for statistical evaluation of MTD performance.
• Examine principal methods utilized in MTD Verification and Certification programs across the U.S.

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Intended Audience

Outline

• ASCE joint task committee on guidelines for certification of stormwater BMPs Committee – 63 committee members from: major stormwater organizations, testing Labs, private sector, manufacturers, and 20 universities


• Introduction
• purpose ‐ aid regulators in establishing certification and verification programs for manufactured stormwater treatment devices (MTDs)
• develop protocols for testing sediment removal in hydrodynamic separators and filters
• listing of existing MTD regulatory programs for sediment removal


• Major components of a testing and certification program
• laboratory testing
• scaling relations
• field testing
• data evaluation
• data reporting
• maintenance


• Developed a protocol for laboratory testing where variables such as flow rate, concentration, particle size, and settling velocity distribution could be controlled to provide statistically valid predictions of MTD sediment removal efficiency performance
• Recommends mass balance methodology to measure removal efficiency of solids flowing through MTD.
• Recommends use of SSC for lab testing of sediment removal
• Discussion of scaling relations and challenges of using scaled models
• Field testing procedures – different than lab testing procedures
• Field testing analysis and performance evaluation

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
