Topic: Writing specifications is always challenging. Writing specifications that incorporate environmental permit requirements is especially challenging. After this presentation, attendees will understand the difference between contract and permit language, how to determine what parts of a permit should be in a contract, and how to translate permit language into enforceable contract language.
Presenter: Dave Jenkins, CPESC Dave has worked in construction erosion control for over 27 years. He recently retired after 22 years as the Port of Seattle Erosion Control/Stormwater Engineer. Prior to the Port, he was the WSDOT Statewide Erosion Control Coordinator, responsible for developing and implementing their first contractor erosion control certification program. All of Dave’s experience is in heavy civil, public works construction, primarily seaport, airport and roadway infrastructure.
Title: Tire Washes: Choosing, Specifying and Using
Topic: In this presentation you will learn how to decide if you need one, how to avoid using one, what to look for if you do need one, how to make them work even better, how to write some specifications.
Speaker: Dave Jenkins, CPESC. Dave has been working on heavy civil public works construction for almost 30 years. In that time, he has been trying to figure out how to avoid using tire washes. It turns out, when you are working a 600 acre earthwork job over four winter rainy seasons, you really do need a tire wash.
Here is a rare beast: a vacuum sweeper with working spray nozzles and nothing dripping out of the back.
This has been such a problem that I included the following language in my erosion control specification:
1.) Vacuum sweepers shall have on-board water spray systems operating at all times.
2.) Sweeper systems shall function per manufacturer specifications including, but not limited to, water spray systems, blowers, vacuum nozzles, hoses, debris hopper, hydraulics and electrical.
3.) At no time shall debris hopper seals leak debris and/or liquids

I wrote this biodegradable wattles specification for a riverbank habitat restoration project.
I wrote the last three sentences for this particular project, which has a 2:1 slope above an intertidal river. We will place 12 inches of compost before installing native plants this winter; without the wattles, wet compost will slide to the base of the slope.
BIODEGRADABLE WATTLES
Wattles shall consist of 100% biodegradable straw, coir, excelsior or compost encased in 100% biodegradable fabric or mesh.
Wattles shall be a minimum of 8 inches in diameter free of cuts tears and damage.
