Workshop A: Methods to Meet New Construction Site Stormwater Quality Requirements
Wednesday, July 18 | 8:00am – 5:00pm

There is increasing pressure on construction site managers to reduce the off-site impacts of storm water runoff on streams, lakes, and estuaries adjacent to their projects. Traditional erosion and sediment control measures, even when properly installed and maintained, will often release highly turbid water to the environment. Recent changes in local, state, and federal rules, such as the Effluent Limit Guideline (ELG) rule released by EPA, are requiring turbidity controls which essentially require chemical treatment. This workshop focuses on the basics of turbidity control, particularly Passive Treatment Systems (PTS), so that participants can design and maintain systems fit to each construction project.

Workshop C: Making Green Infrastructure More Sustainable with Envision, the Sustainable Infrastructure Rating System
Wednesday, July 18 | 1:30pm – 5:00pm

The workshop will be a series of PowerPoint presentations introducing participants to lSI and the new sustainable infrastructure rating system. The presentations will cover case studies of applications of the rating system as an interactive tutorial and also discuss the lessons learned from utilities that have used the tool. The focus of the workshop will be to discuss and determine the applicability of the tool in stormwater infrastructure management.  

Tour: Behind the Scenes at the National Aquarium in Baltimore
Wednesday, July 18 | 4:00pm - 6:30pm

The start of the tour will include a technical lecture by Andy Aiken, an environment engineer specializing in design and operation of aquatic life support systems in zoos and public aquaria. Mr. Aiken will lecture on how aquatic life support systems differ from industrial, municipal and domestic water treatment systems. He and his staff will then lead a tour of the aquarium’s life support systems which process more than 24 million gallons a day. Processes utilized include sand filtration for particulate removal and nitrification, foam fractionation for DOC reduction and disinfection, autotrophic sulfur-based denitrification, ozone contact for disinfection & TOC reduction, gas exchange for CO2 removal, reverse osmosis and CO2 injection for alkalinity and pH reduction, among others.

New York City Water Protection Program Ticketed Breakfast
Friday, July 20 | 7:00am - 7:45am

The City of New York has developed and is managing a multifaceted long-term Watershed Protection Program to enhance and maintain water quality in its three upstate watersheds. The overview will be presented by Lowell Kachalsky from O'Brien & Gere and Jeff Graf from NYCDEP.
