Boulder Park 2018 Annual Report i EXECUTIVE SUMMARY

The Boulder Park Project Beneficial Use Facility (Boulder Park) enhances and enriches agricultural soils in Douglas County, Washington by applying biosolids, a nutrient-rich, organic soil amendment produced by the wastewater treatment system. Boulder Park is jointly permitted, operated, and managed by Boulder Park, Inc. (BPI) and King County Department of Natural Resources and Parks (King County). BPI provides project operations and land application services; King County provides application equipment and project management. This report summarizes annual operational and monitoring information from January 1, 2018 to December 31, 2018.

Three farmers started the Boulder Park Project in 1992 and it has grown to include over 90,000 permitted, tillable acres in primarily dryland wheat production on the Mansfield-Waterville plateau with smaller acreages of canola, sunflowers, and hay. Farmers pay for the soil amendment value of biosolids delivered to their farm. In 2018, Boulder Park Project contracted with 35 wastewater facilities to beneficially use biosolids as a soil amendment on agricultural lands.

Over 25 years of research and field observations by University scientists at the project have shown biosolids applications are an effective alternative to synthetic fertilizers, increasing soil organic matter and moisture retention, improving soil structure, enhancing soil fertility, encouraging microbial activity, increasing crop yields and residues, and maintaining crop quality. Additionally, project participants monitor soil, groundwater, and surface waters to help ensure that the project is protective of public health and the environment.

Boulder Park's operations reflect the values and guiding principles promoted by Northwest Biosolids, as well as the principles of an Environmental Management System for biosolids. Boulder Park continually supports and works towards excellence in biosolids management practices, surpassing regulatory compliance obligations, and providing meaningful opportunities for public participation.

Boulder Park 2018 Annual Report 4 1.0 Introduction

The Boulder Park Project Beneficial Use Facility (Boulder Park), jointly permitted, operated, and managed by Boulder Park Inc. (BPI) and King County Department of Natural Resources and Parks (King County), uses biosolids as a soil amendment on agricultural lands in Douglas County, Washington. Boulder Park is one of the largest farmer-owned and operated, multi-farmer biosolids projects in the United States. Since the first biosolids applications in 1992, the number of project participants has increased from three to over 100 landowners and farmers due to measurable benefits exhibited in their soils and crop yields they have witnessed either first-hand on their own farms or on their neighbors’ farms. Since project initiation, BPI has successfully applied over 2 million wet tons of biosolids for soil improvement and crop production on over 145,000 acres (Figure 1). Why Biosolids? King County Biosolids are Loop nutrient-rich organic Wet Tons material generated 1,688,800 through the process of municipal wastewater Total acres treatment and are of applied: such a quality they can be safely 145,025 recycled and beneficially applied to the land. Biosolids contain Other Participant organic matter, Wet Tons: nutrients, 378,579 microorganisms, metals, sand, Figure 1. Total wet tons and applied acres since 1992. grit, and synthetic and naturally occurring trace organic compounds. The nutrient fraction contains all essential plant macro- and micro-nutrients, such as potassium, phosphorous, sulfur, copper, iron, manganese, and zinc (Figure 2).

Biosolids are an excellent source of nitrogen for crops because microorganisms in the soil convert the nitrogen in the organic matter into plant-available nitrogen gradually over time. This slow release process minimizes the possibility of nitrates leaching out of the root zone because nitrogen is released at rates similar to plant uptake. Over 25 years of biosolids applications have demonstrated many benefits to soil tilth, crop quality, and increased yields (Cogger, 2013, Figure 3).

Boulder Park 2018 Annual Report 6 2.0 2018 Project Summary

In 2018, Boulder Park Other received 125,751 of Participant biosolids and applied Wet Tons: 122,138 wet tons of biosolids 38,596 on almost ten thousand 32% acres of farmland (Figure 4).

Thirty-five wastewater Total facilities participated at Acres Boulder Park and twenty- Applied seven delivered biosolids in 2018: (see Appendix B, Tables 1A 10,015 and 2A for application and storage activities). To join the project, facilities enter King County into a three-party agreement Loop with both King County and Wet Tons: BPI to beneficially use their 83,542 biosolids. All wastewater 68% treatment facilities ensure that their biosolids meet all Figure 4. Wet tons and acres applied in 2018. quality requirements, while King County and BPI ensure that delivered biosolids are managed in accordance to all applicable permits and regulations.

Biosolids Delivery and Storage

Temporary staging of biosolids occurs in designated areas within project sites that have been scheduled for applications. Staging areas are reviewed and approved by Ecology. Typically, biosolids are staged on site for a few days or weeks, except during the winter when biosolids can be stored several months or more until land application can resume. At year's end, there were 18,381 wet tons of biosolids stored in Figure 5. Loop truck delivering biosolids to a Boulder Park delivery designated over-winter site

Boulder Park 2018 Annual Report 7 staging areas for spring applications in 2019 (refer to Appendix B, Table 2 and 2A for storage activities).

The Right Amount of Nitrogen (and Phosphorus)

Agronomic biosolids application rates are determined for each individual site by scientists from Washington State University (WSU) Cooperative Extension and are approved by Ecology. Site specific biosolids application rates are based on the crop's requirements for nitrogen needs, WSU fertilizer guides, historical yield potential, residual soil nitrogen, and the plant-available nitrogen from the biosolids (Cogger et al., 2013).

The approved application rate is the desired or “target rate.” During applications, the number of spreader loads is tracked, along with periodic mass balance calculations, to ensure that the actual application rate is within ±15 percent of the target rate, which is an acceptable range for bulk fertilizer applications.

Project Operations

Biosolids currently used at Boulder Park are classified by federal and state regulations as either Class A or Class B. Class B means that biosolids have been treated by a process designed to substantially reduce pathogen indicators to 95-99% pathogen free, but is not 100% pathogen-free. Class B biosolids must meet additional requirements including, but not limited to, site management and access restrictions. For this project, biosolids are typically applied to wheat stubble 13-21 months prior to harvest. This ensures that crops are never harvested prior to the required 30-day harvest Boulder Park 2018 Annual Report 8 waiting period per state and federal regulations. Additionally, access restriction signs are posted at the primary access to each application field stating the dates for access restriction beginning with the first delivery and extending until 30 days after completion of the biosolids application.

Biosolids are applied by BPI personnel using standard farming practices. Large four-wheel drive tractors pull industrial manure spreaders across the site to uniformly apply biosolids at the approved agronomic rate. Equipment is regularly calibrated by BPI personnel to ensure application of biosolids is done as accurately as possible.

Farmers may incorporate the biosolids using a cultivator or other means appropriate for residue and soil conditions in the field. BPI personnel incorporate biosolids delivered to Boulder Park that do not meet vector attraction reduction requirements set forth in Chapter 173-308-180 WAC. BPI provides a 6-hour tillage service that ensures the incorporation requirement in Chapter 173-308-210(4)(b) WAC is met since the farmer may not be immediately available at the time of application.

Research and Innovation

Boulder Park has been an enthusiastic partner in supplying equipment, labor, and suitable sites to assist Washington State University Cooperative Extension (WSU) and University of Washington (UW) scientists in dryland wheat and biosolids research over the last 25 years. WSU scientists have been evaluating the effect of biosolids on nutrients, soil conditioning, and crop quality since the project began. Through long-term research, we know that that biosolids have both short-term and long-lasting positive impacts on soil and crop health (Cogger et al., 2013; Sullivan et al., 2018).

Researchers have also been studying the impact biosolids application has on carbon storage in soils. WSU and UW scientists have

found significant increases in soil carbon from Figure 7. Dave Ruud, BPI Operations biosolids applications at Boulder Park fields Manager, comparing wheat grown in (Brown et al., 2011). Through carbon storage, biosolids-amended soils (left) with wheat grown using synthetic fertilizer (right), biosolids applications can help reduce May 2017. greenhouse gases and mitigate climate change.

Boulder Park 2018 Annual Report 9 GP-17 Research Plots

Figure 8. A time lapse video of GP-17 showed the improved infiltration of water, a result of increased organic matter, in biosolids applied fields. The 2018 harvest marked the 23rd year of continuous data collection at the GP-17 test plots. GP-17 was planted to canola for the first time and this was the second harvest since biosolids were last applied in October 2015. Treatments at this site consist of three rates of biosolids (2, 3, 4.5, dry tons/acre), a fertilized treatment (50 pounds/acre of Nitrogen), and an unfertilized control.

Overall, research plots applied with biosolids yielded more seeds and more oil than the unfertilized control and commercial fertilizer plots in 2018 (Figure 9).

Boulder Park 2018 Annual Report 10 This year, Washington State University scientists published a paper (Sullivan et al., 2018) on the long-term impacts of biosolids application on this research plot, outlining how biosolids have:

 Increased soil organic matter by as much as 50% in the topsoil  Enriched the supply of immobile nutrients like phosphorus and zinc in the topsoil  Not increased soil salinity, despite repeated applications  Worked as an effective replacement for commercial nitrogen fertilizers  Increased crop yields

WSU scientists also published a biosolids application rate calculator (Sullivan, Bary, and Cogger, 2018) to help others effectively manage the nutrients in biosolids and apply them only in the amounts needed by the crop.

Soil Health In 2018, the Soil Health Institute selected the Boulder Park GP-17 research plots for a new study on soil health indicators. WSU scientists will be testing for over 50 soil health indicators over the next several years, beginning in spring 2019. The Boulder Park research plots are one of only two biosolids sites included in the study.

In addition to the Soil Health Institute work, WSU scientists also began examining the potential impacts of repeated biosolids applications on microplastics and silver nanoparticles in soil. Very little is known about the fate of these particles in soil or how they affect soil quality. In fact, this is the first study of its kind. Figure 10. Keeping track of yield numbers from the harvest Precision Agriculture

A significant number of Boulder Park farmers participate in the Conservation Stewardship Program (CSP), which is implemented by the U.S. Department of Agriculture, Natural Resource Conservation Service (NRCS) to promote conservation practices such as precision agriculture and conversation tillage farming practices. In 2015, the NRCS, King County, BPI, Ecology, and farmers developed a system to ensure that biosolids application met the Nutrient Management (590) Standard and requirements of CSP. Although it is more

Boulder Park 2018 Annual Report 11 complex to calculate agronomic rates for CSP fields, BPI continues to successfully meet CSP requirements.

Technological Advancements

A key part of implementing precision agriculture effectively is adopting technological advancements. All of the tractors are equipped with Global Positioning Systems (GPS) and automatic steering systems to provide applications that are more precise and improved documentation and mapping capabilities. GPS technology increases the precision of biosolids Figure 11. Trimble GPS display in tractor applications by decreasing overlap between passes, which means more acreage can be applied with the same amount of biosolids. GPS can improve recordkeeping by accurately documenting the location and acreage applied for each facility. GPS technology allows Boulder Park to better serve farmers participating in CSP by having the capability to apply varying rates of biosolids to different zones within a field (Figure 12). Figure 12. Zone map for nutrient management programs

3.0 Environmental Monitoring

Every year, Boulder Park goes beyond regulatory requirements for environmental monitoring. Throughout the lifetime of the project, we have collected:

 Biosolids quality data  Pre-application soil samples for background nutrient and metals data  Post-application soil samples to document any changes  Groundwater well and surface water quality data pre- and post- application  Periodic crop quality data

Our extensive monitoring efforts allow us to be proactive about managing biosolids applications. For instance, we were the first biosolids project to start self- regulating applications based not only on nitrogen, but also on phosphorus levels. We also test for all regulated metals (Figure 13).

All sampling and analyses are conducted in accordance with approved field and laboratory methodologies. Raw laboratory data sheets, quality control/quality

4.0 Public Involvement and Communication

Since the initiation of the Boulder Park Project, considerable effort has gone towards providing information to the general public and local agencies about the project and biosolids recycling in general. As required by state regulations, all sites are posted for at least 30 days prior to application to allow for public notice and comments. Public Figure 14. King County employees touring Boulder Park Project, June 2018. involvement has been encouraged by providing opportunities for public interaction with project participants via informal open houses and on project tours. Tours give interested persons the opportunity to learn about biosolids, biosolids-amended soils, and biosolids grown crops; to

Boulder Park 2018 Annual Report 13 see the Boulder Park Project area; observe biosolids delivery, storage, and land applications operations; and ask questions. In addition to planned tours, BPI has an open door policy at their Mansfield office for visitors wishing to learn about the project.

In 2018, 62 people toured the Boulder Park Project. Tour participants included:

Boulder Park 2018 Annual Report 14 5.0 Regulatory Information and Permits

Boulder Park Project Beneficial Use Facility is jointly permitted, operated, and managed by BPI and King County. The project was granted Final Coverage under Chapter 173-308 WAC, the General Permit for Biosolids Management on January 26, 2016. Coverage under the General Permit is effective for five years expiring in 2020.

Ecology requires all sites obtain a landowner authorization for biosolids application and the site be posted for public notice for 30 days to allow for public comment before a site can be added to Boulder Park’s permit coverage. Ecology inspects and approves application sites prior to biosolids applications. In addition, Ecology also approves site-specific biosolids application rates based on WSU's recommended nitrogen fertilizer needs of the crop, the amount of plant available nitrogen in the biosolids, and existing nitrogen content in the soil. The CDHD receives documents relative to the project for review and comment.

1 Samples will be collected from wells within 1,320 feet of application sites within one year of biosolids application.

2 All water quality parameters will be repeated one year after biosolids are no longer actively applied within 1,320 feet of a well, whether due to discontinued use of individual fields or termination of the project. 3 No Enterococcus samples collected in 2018. A discussion with Cascade Analytical Laboratory suggested that this analysis was unnecessary since fecal coliform testing could be used as an bacteriological indicator for water quality conditions that is used to determine additional testing needs.

1 Samples will be collected from surface waters within 500 feet of application sites annually (if present) within one-year of biosolids application to the sites. During a significant storm event, samples for nutrient and bacteriological parameters may be collected when operationally possible. 2 All water quality parameters will be repeated one year after biosolids are no longer actively applied to the application sites, whether due to discontinued use of individual fields or termination of the project. 3 No Enterococcus samples collected in 2018.
