Application Materials for State Stormwater Discharge Permit Applications
The Vermont
Stormwater Management Program is announcing several major changes
to its Operational (i.e. non-construction) Stormwater Discharge Application
process for projects seeking coverage under General Permit 3-9015,
and for those projects seeking coverage under an Individual Stormwater
Discharge Permit. These changes have been discussed with a number of consultants and with representatives of ACEC over the past year.
As you will read in the new "Application Instructions for State Stormwater Discharge Permits", we have extensively revised the 3-9015 Notice of Intent (NOI), the Individual Stormwater Discharge Permit Application form and the associated Schedule A's, as well as developed "worksheets" for stormwater treatment practices (STPs) , waivers, and credits. While the new forms will require more information than our previous forms, they serve to consolidate information regarding required design elements that previously was provided in the application narrative. They
will also provide additional technical guidance in areas of the VSWMM
where problems were frequently noticed in reviewing applications.
An important associated change
to the application process will be the introduction of a complete screening
of applications prior to their initial acceptance by the Program. Incomplete
or erroneous applications will be rejected, and will be returned with
a checklist of deficiencies. This change is necessary because
it has become evident that an increasingly inordinate amount of time
is currently being spent by our limited staff in back-and-forth discussions
with consultants in an effort to correctly complete sub-standard applications. Unfortunately
this effort comes at the expense of increased processing time for those
applications that are both administratively and technically complete. Implementation
of these new and comprehensive forms, coupled with the initial application
screening should lead to greatly reduced permit processing times, as
well as the creation of a new "express lane" for
relatively simple projects that employ standard practices for treatment
and control.
In summary, implementation of these changes will serve as a major step towards increased reliance on the certification by stormwater designers in our review of applications, and therefore significantly decreased application review times.
The new forms and complete instructions can be found below including
links to the new application forms and instructions.
Please be aware that the
new forms will be required for all applications received by the Stormwater
Program after June 15, 2006.
Instructions for use:
All
of the application forms must be downloaded, while the "worksheets"
can be downloaded as necessary depending on your project and which
STP, waiver and credit you might be employing for each discharge point. Essentially,
the Schedule A summarizes how compliance with the 5 stormwater criteria
has been achieved for each discharge point. As has always been the
case, the designer will indicate on the Schedule A how she/he has achieved
compliance with each of the stormwater criteria, either through the
use of an STP, a waiver, a credit, or some combination of the three. Now,
however, each STP, waiver or credit will also have a required worksheet
and, in some cases, accompanying guidance which will help the designer
demonstrate that she/he has complied with all of the required elements
in the VSWMM.
An
application will not be considered administratively complete, will not proceed on to technical review and will be returned to the designer (and the applicant copied) unless
all
of the items listed on the NOI form and on the narrative checklist
are provided, and all of the required worksheets for any STP, waiver
or credit listed on the schedule A's for a project are completed
and included with the submission.
The completion of these worksheets does not automatically constitute compliance with the 2002 VSWMM, and when in doubt, designers should review the 2002 VSWMM for verification of standards, treatment practices, waivers or credits or contact the Stormwater Section at 802-241-4320.
Please
note that these worksheets will be updated as necessary and thus you
should ensure that you have the most recent version of the worksheets before
submitting your application. You are welcome to send any questions,
comments or feedback to Megan Moir.
