prohibits the dumping of improper materials into the sto water onveya ce syst
Graphical icons, either illustrating anti-dumping symbols or ' ages eiving
water fauna, are effective supplements to the anti-dumping mess e. All storm ain
inlets and catch basins within the project area a stenciled with e
language (such as: "NO DUMPING — DRAIZibitive
TO AN") and/or graphical icons
to discourage illegal dumping. Signs and p Lang a and/or graphical icons,
which prohibit illegal dumping, must be p sted at p li cce oints along channels
and creeks within the project area.- Leg' ility of sten ' d sign must be
maintained.
Properly Design Outdoor Material Storage Areas \
Outdoor material storage areas refer to storage area, or stobage facilities solely for the
storage of materials. Improper storage of materials ou or; may provide an
opportunity for toxic compounds, o' ease, heavy m Is, nutrients, suspended
solids, and other pollutants to er the sto water conveyance system. Where
proposed project plans i de outdoo r'as or storage of materials that may
contribute pollutant o the storm to conv ance system, the following Structural
or Treatment BMPs ar equi=d:
l) Materials with the potential to co tamin to storm water must be: (1) placed in an
enclosure suc as, but not limite to, a c binet, shed, or similar structure that
prevents co tact th runoff or spi e o the storm water conveyance system; or
(2) prote ed by seco ary containmen structures such as berms, dikes, or curbs.
2) The sto age area st be ved and sufficiently impervious to contain leaks and spills.
3) The orage area ust ve a oof or awning to minimize collection of storm
wa r within vhq sec da ontainment area.
g. Properly De!'fgn Trash StZrage Areas
trash storage area refers to an area where a trash receptacle or receptacles
<< LL are located for use as a repository for solid wastes. Loose trash and
debris n be easily transported by the forces of water or wind into nearby storm

ollowing Stru ral or Treatment Control BMP requirements (individual single
family r,�si nces re exempt from these requirements):
1)ITrash container areas must have drainage from adjoining roofs and pavement
diverted around the area(s).
?) Trash container areas must be screened or walled to prevent off-site transport of trash.

Attachment 4
h. Provide Proof of Ongoing BMP Maintenance
Improper maintenance is one of the most common reasons why water quality controls
will not function as designed or which may cause the system to f e irely. It is
important to consider who will be responsible for maintenancef a permiw3ent BMP,
and what equipment is required to perform the maintenance per
y. f
project review, if a project applicant has included or is req 'red tru ral
or Treatment Control BMPs in project plans, the Permitt shall the
applicant provide verification of maintenance provision roughs as m y
be appropriate, including, but not limited to legal agreement ,coQA
mitigation requirements and/or Conditional Use Permits.
For all properties, the verification will includ he dev oper's signed statement, as
part of the project application, accepting res onsibili fo 1 structural and treatment
control BMP maintenance until the time t pro is ns ed and, where
applicable, a signed agreement from the ublic enti s ing r ponsibility for
Structural or Treatment Control BMP aintena ce. The transfer o property to a
private or public owner must have conditi s equinng t reci nt to assume
responsibility for maintenance of any Structural or -reatm nt Control BMP to be
included in the sales or lease agreement for that pro ierty, a d will be the owner's
responsibility. The condition of transfer shall include ro ision that the property
owners conduct maintenance inspec ' fall Structural o Treatment Control BMPs
at least once a year and retain of of insp ion. For residential properties where the
Structural or Treatment trol BMP a loc ted within a common area which will
be maintained by a meowner's o ation, language regarding the responsibility
for maintenance must incl ed i e proj ct's conditions, covenants and
restrictions (CC&Rs). Prin ed a ational m terials will be required to accompany
the first deed transfer to highlight th existe ce of the requirement and to provide
informationon w at storm water ma agem t facilities are present, signs that
maintenance is ee how the necess aintenance can be performed, and
assistance th the Perms a can provide. a transfer of this information shall also
be require ith any seq t sale of the property.
If Stru ral or T tme Co of BMPs are located within a public area proposed for
transfer, ey 11 be re onsibility of the developer until they are accepted for
transfer by t County or other appropriate public agency. Structural or Treatment
Control BMPs proposed for transfer must meet design standards adopted by the
p is entity for the BMP installed and should be approved by the County or other
ppro ate public agency prior to its installation.

NPDES Phase II Freouently Asked Questions
Does each agency have to prepare their own plan? What if the regional board does not
approve one agency's plan, do the others get a permit?
Each agency does not need to have their own plan. The MCSTOPPP agencies
can be co -permittees under one permit, using the Action Plan 2005 as their
one storm water management plan.
However agencies can have their own plans if they prefer. Santa Clara Valley URPPP
agencies each have their own individual storm water management plans (which they call urban
runoff management plans) to go along with the SCVURPPP program's plan. This obviously,
can make for more work for the co -permittee, the program managers, and Regional Board staff
however.
If there is a violation in one agency under the permit, who is
Responsible- the JPA, the agency where it occurred, or all under the joint permit?
Each agency is responsible for the storm drain system that it owns or
operates. If there is a violation in one agency under the permit, then the
agency is responsible. Typically Regional Board staff will cite the
individual agency with a Notice of Violation (NOV).
Can agencies have different standards to fulfill the stormwater plan requirements? For
example can street sweeping in one agency be weekly and in another monthly? Or will
the regional board require all agencies to meet the most stringent
standard?
The Regional Board wants to see equity across agencies and stormwater programs—that is
why they are getting more prescriptive in the permit language for the Phase I programs. But
agencies can have different standards as long as they meet the minimum standards as
outlined in the performance standards. In the MCSTOPPP Action Plan 2005, some
performance standards allow for alternative approaches (e.g., See Storm Drain Facilities under
Municipal Maintenance performance standards for which one performance standard allows for
the development of an alternative storm drain facility pollution control plan.)
What is being considered for TDML limits? There is a concern if numerical limits are
set.
The essence of TMDLs is to set Total Maximum Daily Loads for pollutants that are impairing
local waterways and the Bay. Stormwater agencies are required to implement best
management practices to be in permit compliance. For the TMDLs, stormwater agencies will
be implementing BMPs that will lead to the attainment of water quality standards. The TMDL
section of the Action Plan 2005 plan contains the TMDL planning schedule proposed for Marin.
Most of the TMDLs for Marin focus on the Tomales Bay watershed. Eastern Marin creeks are
being listed for is the pesticide Diazinon. MCSTOPPP has a regional strategy prepared in
cooperation with BASMAA to deal with Diazinon. Agencies should participate in the TMDL
process to ensure that their concerns are heard, MCSTOPPP works through BASMAA to voice
our concerns.

What is the penalty for a municipality that doesn't pay Its fees or that fails to submit the
N01?Any permit noncompliance constitutes a violation of the Clearl'Water Act and the Porter -
Cologne Water Quality Control Act and Is grounds for enforcement action and/or removal from
General Permit coverage. In the event that the Permittee is removed from General Permit
coverage, the Permittee will be required to seek coverage under an Individual or alternative
general permit.
