Current through Register Vol. 24-06, March 15, 2024
(1)
Inventory required. WSDOT shall prepare and maintain an inventory of all state
highways in the Puget Sound basin. The purpose of the inventory is to determine
where water quality BMPs need to be installed, to assist identification of
priority projects, and to provide a basis for the evaluation of the program.
WSDOT shall begin its inventory on highways with an ADT of fifty thousand or
greater. The inventory and rating of highways with an ADT of less than fifty
thousand shall be sufficient to provide projects for the six-year capital
improvement program plan.
(2)
Contents of inventory. The inventory shall be developed for homogeneous highway
segments and shall include, but not be limited to:
(a) Highway segment identification including
name, location, type, traffic volume classification, local government(s) with
jurisdiction, interested tribes, and WSDOT district;
(b) Status of stormwater management as
follows: (i) BMPs are present and/or a local government is receiving and/or
treating the highway runoff; (ii) BMPs are feasible or the local government
will receive and/or treat highway runoff; or (iii) BMPs are not practicable;
and
(c) Name of any water quality
project completed since the effective date of this chapter, length of project,
year of construction, and cost.
(3) Priority rating and ranking.
(a) WSDOT shall establish an annual project
priority list for each WSDOT district within the Puget Sound basin. For each
fiscal year WSDOT shall select needed improvements for each district
inventoried as required by subsection (1) of this section. WSDOT shall divide
these needed improvements into projects, considering funds available but in no
case less than one project per year in each district unless all needed projects
are completed.
(b) Priority rating
criteria. WSDOT shall develop a priority rating and ranking system and submit
it to ecology for concurrence.
(c)
Priority ranking. WSDOT, using the priority ratings and rankings prepared using
the system required in subsection (2)(b) of this section, shall determine which
projects are to be implemented in each WSDOT district during the fiscal year.
WSDOT may modify this ranking for good reason including the participation in a
joint project proposed by a local government or tribe.
(4) Capital improvement program plan.
(a) The capital improvement program plan is
to promote efficient use of resources, to coordinate projects, to aid
compliance with the long-range program targets set forth in subsection (5) of
this section and to ensure that difficult projects and those that require
lengthy lead time are constructed in a reasonable time.
(b) WSDOT shall prepare a biennially updated
water quality capital improvement program plan. WSDOT shall consult with
ecology, tribes, and local governments throughout the planning process
including the inventory. The capital improvement program plan shall be for a
six-year period and include the following:
(i)
An inventory of potential projects for the six-year period, including fiscal,
technical, work force, legislative requirements, restrictions, and an initial
evaluation of their relative priority;
(ii) A schedule for potential execution of
projects in a long-range program list which considers priority relationships of
projects coupled with legislative, fiscal, technical, and work force
restrictions;
(iii) Selection of
projects for early action from this schedule; and
(iv) Formal adoption by WSDOT after public
review.
(c) Ecology
shall review the proposed WSDOT capital improvement program plan and submit
written comments to WSDOT before public review and again before adoption by
WSDOT.
(d) After a public hearing,
WSDOT shall adopt the capital improvement program plan after making appropriate
revisions deemed necessary by public input.
(5) Long-range program.
(a) WSDOT shall complete all practicable BMP
projects or transmit highway runoff to tribes or local governments for
stormwater treatment for highways with an ADT of fifty thousand and greater by
December 31, 2005, and for other highways by December 31, 2015.
(b) At least every six years WSDOT and
ecology shall evaluate these target dates. Ecology or WSDOT may initiate
revision of the target dates. In evaluating any proposed revision of a target
date, ecology and WSDOT are to consider factors including, but not limited to,
the number and projected costs of the projects yet to be completed, the degree
of difficulty to construct the remaining sites, the projected level of funding,
any revisions to the state water quality standards and any revisions to the
manual required by WAC
173-270-030(1).
(6) Negotiations. Before
transmitting to or requesting treatment of highway runoff by a tribe, local
government or property owner, WSDOT shall negotiate with the tribe, local
government, or property owner. WSDOT shall provide relevant information that
shall include, but not be limited to, existing agreements to accept highway
runoff, characteristics of the highway runoff, the reasons WSDOT is not
treating the runoff on its own right of way and any proposed financial
considerations for quality and/or quantity control.
(7) Disposal sites. WSDOT shall prepare an
inventory, by district and maintenance area, of all sites, including all known
inactive sites, where WSDOT disposes highway sweepings and sediments from
stormwater facilities maintenance activities. Inventory information for WSDOT
owned and leased sites and sites WSDOT for which has an easement shall include
a scaled map illustrating property boundaries and the extent of the fill area,
and where possible, an estimate of the volume of the fill present.
