LHINC Projects In Action

After a pressurized wastewater disposal system's pipe network is constructed (but before the piping is covered), the pump must be tested. To the right is an example of such a pressure test. The height of the water streams correlate to the system pressure. Each stream must also be equal in height to each other, or else the wastewater will not be evenly distributed throughout the entire area. And yes, we use potable water for the test.

Multi-Sector General Permit Information

On August 18, 2006 a new stormwater permit program for industry became effective. The Multi-Sector General Permit (MSGP) covers many different types of industrial facilities, which are listed by Standard Industrial Classification (SIC) codes, as required by the federal Clean Water Act.

What does this mean?

All listed facilities were required to file a Notice of Intent (NOI) to obtain coverage under the permit as of the effective date. Permitted facilities must then prepare a Stormwater Pollution Prevention Plan (SWPPP) and institute the best management practices (BMPs) at the facility by May 15, 2007

Directions on how to determine a facility SIC code is available on the State of Vermont website here (pdf):

What are the options?

If all of the industrial materials and activities at your facility are protected from exposure to rain, snow melt-water and runoff, then the facility may qualify for the “No Exposure Conditional Exclusion”, and a permit is not required. More information is available on the Vermont State website here:

Llewellyn-Howley Incorporated is experienced in MSGP permitting and preparation of SWPPPs. Our staff has written dozens of SWPPPs in southern New England in the 1990s. We can assist you to make a “No Exposure” determination or assist you in permitting.

Wastewater Permit Exemptions Will Soon Become Void

On July 1, 2007 all Town Wastewater Ordinances are superseded by the Vermont Chapter 1 Wastewater System and Potable Water Supply Rules unless the Town has been delegated authority to implement local rules.

What does this mean?

All previous wastewater/water exemptions are voided on July 1, 2007 for unimproved “pre-existing” and “existing exempt” lots. Several other exemptions for existing single-family residences on single lots will also be terminated. This means that a State Wastewater System and Potable Water Supply permit, meeting the current State Rules will be needed to develop these lots after the sunset date.

What can you do?

There is still time to permit and construct an upgrade or replacement to an existing system or a new wastewater and water supply system before the deadline and be only subject to a Town permit. The time is running short, however, and a new house permit means that the house and wastewater system must be “substantially complete” before July 1, 2007. In some cases, existing seasonal camps can be upgraded to year-round residences or bedrooms can be added to existing and/or upgraded wastewater systems under a town permit before July 1, 2007.
