BOARD OF COUNTY COMMISSIONERS
AGENDA REQUEST
TO: Board of County Commissioners
Mark McCauley, County Administrator
FROM: Sophie DeGroot, Noxious Weed Control Coordinator
DATE: `, W evni 26'
SUBJECT: Noxious Weed Free Certification Program
STATEMENT OF ISSUE:
Washington's Noxious Weed Law (RCW 17.10) established that all landowners are responsible for helping
to prevent and control the spread of noxious weeds at their own expense. When landowners and
managers have access to certified weed-free materials, the chances of noxious weeds being spread
drastically decreases. Noxious weeds often spread at construction or renovation sites due to the
disturbances that remove established vegetation and leave the surface exposed and free of competition.
When materials are brought into these sites and projects, seeds can be moved great distances. This is also
true for materials such as mulch and woodchips that may travel across hundreds of miles and end up in
someone's yard. Providing weed-free materials prevents this spread of noxious weeds and keeps a wide
variety of lands healthy and weed-free.
While Scotch broom is not required for control across Jefferson County as its extent is vast, the Noxious
Weed Control Board did vote to require control of Scotch broom within 100-ft of aggregate piles and
storage facilities. This is to curb the spread of seeds to areas that are not currently infested with Scotch
broom.
ANALYSIS:
The Noxious Weed Control Board has created a certification program in which a Weed Board employee
would inspect a site (gravel pit, storage space, compost facility, etc.) to determine how many noxious
weeds are present. The Weed Board will also work with these sites to control their noxious weeds and
come into compliance. The program is entirely voluntary, but provides an important service to the citizens
and business owners in Jefferson County.
FISCAL IMPACT:
There is no additional cost for the County to implement this program. Keeping it free of charge for
participants will incentivize businesses to seek out an inspection and receive certification. If we can limit
the spread of seeds and propagative parts of noxious weeds, the cost of controlling noxious weeds
decreases for everyone.
RECOMMENDATION:
I recommend that the Board of County Commissioners approve of the Noxious Weed Board's Program
Standards in order to make Noxious Weed Free Certifications and Inspections available to aggregate pits
and storage facilities as soon as possible. The Noxious Weed Control Board approved of the program (with
minor changes that have since been made) at their November 27, 2023 Board Meeting.

Washington's Noxious Weed Law(RCW 17.10) established that all landowners are responsible for
helping to prevent and control the spread of noxious weeds at their own expense. When landowners
and managers have access to certified weed-free materials, the chances of noxious weeds being spread
drastically decreases. Noxious weeds often spread at construction or renovation sites due to the
disturbances that remove established vegetation and leave the surface exposed and free of competition.
When materials are brought into these sites and projects, seeds can be moved great distances.This is
also true for materials such as mulch and woodchips that may travel across hundreds of miles and end
up in someone's yard. Providing weed-free materials prevents this spread of noxious weeds and keeps a
wide variety of lands healthy and weed-free.
The following document detailing the proposed Noxious Weed Free Certification Program was prepared
with guidance from the North American Invasive Species Management Association (NAISMA) and the
Clallam Noxious Weed Control Board's varying weed free programs. It has been adjusted to be
introduced in Jefferson County. Creating a noxious weed free program is one pathway to the prevention
and management of noxious weeds.The standards are designed to support cross-jurisdictional
cooperation, provide assurance to all participants that certified materials meet a minimum acceptable
standards, and to generally limit the spread of noxious weeds through materials such as mulch,
woodchips, and gravel.This program will not include the certification of forage and hay, as that is run
through the Washington State Department of Agriculture.
As the Noxious Weed Coordinator, I propose that the County adopt this program,free-of-charge,to all
material sources in Jefferson County. Prevention of seed proliferation is a top priority when it comes to
controlling the spread of noxious weeds. By stopping the spread of seeds in the first place,this program
can also help limit the financial burden and time commitment placed on individual landowners who are
required to control noxious weeds on their property.The Noxious Weed Control Board voted to approve
this policy on November 27, 2023.

Jefferson County Noxious Weed Free Aggregate Certification Standards
INTRODUCTION
There is a growing demand in North America for the use of certified weed free gravel, soil, and other
aggregate materials to limit the spread of noxious weeds.The Jefferson County Noxious Weed Control
Board's Mission To protect lands within Jefferson County from the degrading impacts of noxious weeds
by educating residents, property owners, land managers, and public agencies in how to serve as
responsible stewards and aid in the protection and preservation of the land,water, and natural
resources.
The goal of a noxious weed free program is to work with local agencies and businesses to provide
guidelines, standards, and set minimum goals for a weed free Jefferson County.
DEFINITIONS:
Area of origin: Where the material is stored
Borrow/ Fill Pit:A location where the soil or other natural deposits on or in the earth are removed from
their location to make them suitable for use elsewhere.These areas include, but are not limited to:
surrounding ditches,topsoil piles, gravel/sand piles, fence rows, roads, easements, rights-of-ways,
working areas, storage areas, and a buffer zone surrounding the area. All areas must be included in the
inspection.
Inspector: A Jefferson County Noxious Weed Control Employee or designee.
Gravel: Small stones or pebbles, or a mixture of these with sand, stone, and gravel, as well as recycled
materials such as concrete of asphalt.
Aggregate material: Substances such as mulch, woodchips, gravel, and borrow or fill coming out or going
into the pit area.
Noxious Weed: a plant that when established is highly destructive, competitive, or difficult to control by
cultural or chemical practices.
Responsible Party: The individual or representatives of the entity that controls, directs,or manages the
operation of the site.
Propagules: Any part of a plant capable of enabling it to reproduce (seeds, roots, and/or stolons).
Soil:The natural medium for the growth of land plants on the surface of the earth; composed of organic
and mineral materials.
JEFFERSON COUNTY MINIMUM STANDARDS:
Revised 1/16/24
In order to receive a Noxious Weed Free Rating from the County:
1. Aggregate material shall be inspected by the authority designated by the Jefferson County
Noxious Weed Control Board
2. Aggregate material shall be inspected in the area of origin
3. Aggregate material shall be free of those species identified in Appendix A.
4. Gravel/borrow area which contains any species outlined in Appendix A, may be certified if the
following requirements are met:
a. Area upon which the gravel/borrow material was mined was treated to prevent seed
formation or seed ripening to the degree that there is reduced risk of dissemination of
the seed, or any injurious portion from such species, or the propagating parts of the
plant are not capable of producing a new plant.
b. Weeds are treated according to best management practices, prior to development, or
distribution of propagative parts.
5. When opening a new gravel pit or expanding an existing gravel pit with weeds present,topsoil
and materials and material should be removed and stockpiled appropriately. Infested material
must not be moved to vehicle traffic area (i.e. parking lots, road sides, construction sites).
An inspection certificate, as seen in Appendix D, shall document that the above requirements have been
met based upon a reasonable and prudent visual inspection 1-2 times per year.
Facilities will then display the graphic from Appendix E in a public-facing place where buyers can see it, if
applicable.This will provide transparency and provide further information on the meaning of being
"Noxious Weed Free."
A list on the County Noxious Weed Board website will be updated and maintained as the official source
for which sites have been inspected and what certification they received.
Appendix A:Jefferson County Noxious Weed Control List
Revised: 1/8/24
The designated authority shall inspect sites for these prohibited species.
Species can be petitioned for addition or removal at the first Jefferson County Noxious Weed Control
Board Meeting of each year.

Does This Rock Source Meet Forest Service and/or Clallam County Requirements for Use?
The Inspector will circle or highlight the option that best describes this quarry.This rating is not an endorsement.
Option A This rock source exceeds requirements.Invasive plants are rare to absent in quarry.
Use of materials would almost certainly not contribute to the spread of invasive plants.
This rock source meets requirements.Invasive plants are uncommon in quarry, and easily isolated.
• Invasive plants that are present—even those that are easily isolated-are not listed as high
priority or regulated species and/or are not species of particular concern.
• Non-regulated or lower priority species may be present,but are not pervasive.They may be
present in small,isolated patches within or near the rock source, but can be isolated by simple
Option B precautionary measures.
• Typically,less than 10%of the pit either has weeds growing on it or potentially could contain
weed seed or other propagules,and these areas are easily isolated from rock source materials.
• Treatment of weeds is recommended,but use of materials from this source as found on the day
of inspection would most likely not contribute to the spread of invasive plants on Forest Service
lands if simple precautionary measures are followed. County road or restoration projects may
require additional mitigation.
This rock source meets minimum requirements.
Invasive plants are common in quarry;precautionary measures will need to be followed carefully to
prevent spread.
• Any regulated species listed as priority or species of particular concern are absent in or around
II
rock source*.
• Non-regulated species listed as priority are present in patches,but some portions of the rock
source are relatively free of weeds,are most likely are not contaminated with a significant
Option C amount of propagules(seeds,roots,etc.)from these species.
• Typically,between 10—50%of the pit will have weeds growing on it and/or potentially could
contain seed or other propagules from these species,and these areas are easily isolated from
rock source materials.
• Treatment of weeds is highly recommended,and may be required as a condition of use by the
Forest Service or County projects. Distribution of materials from this rock source may contribute
to the spread of noxious weeds if precautionary measures are not followed carefully.County road
or restoration projects may require additional mitigation.
This rock fails to meet minimum requirements for use on Forest Service lands or Clallam County
Projects.
Distribution of materials from this rock source would likely contribute to the spread of noxious weeds.
• Regulated or weed species listed as priority 1 and/or species of particular concern are present in
Option D or around this rock source,OR weed species listed as priority 2 by the Forest Service are present
to the extent that plants and/or propagules(seeds,roots,etc.)are present in significant portions
(greater than half)of the rock source and/or cannot be isolated by simple precautionary
measures.
• Treatment of weeds followed by subsequent inspections will be required as a condition of use.
