Draft 2020 Annual Report and Work Plan Documents for the Oceano Dunes SVRA

State Parks provided the 2020 Draft ARWP and attachments (below), and based on Scientific Advisory Committee and SLO County APCD review of the first draft, the ARWP was deemed not acceptable in its current form. The SLO County APCD believes that the ARWP can be revised in time to approve and implement the winter 2020/2021 mitigations, however we must move quickly to revise the ARWP to meet required timelines. THe APCD, Parks and SAG anticipate coming to an agreement on a provisionally approvable ARWP in early October and holding a public workshop before or during the October 23, 2020 Hearing Board update meeting.

July 1, 2020 Update

SLO County APCD staff has received several inquiries by the community regarding air quality downwind of the Oceano Dunes State Vehicular Recreational Area (Oceano Dunes), SLO County APCD has developed a Frequently Asked Questions Guide (FAQ Guide) to help answer questions and help the public understand what immediate and long-term impacts may be realized from the COVID-19 related temporary closure of the Oceano Dunes.

Frequently Asked Question Guide - June 2020

May 29, 2020 Update

At the May 29 APCD Board Meeting the Scientific Advisory Group provided a presentation on the Oceano Dunes mitigation efforts. The presentation is linked below in PDF format. 

SAG Presentation

April 13, 2020 Update

As mentioned in our April 1 update, the Governor ordered the full closure of California State Parks to all recreational vehicular traffic effective March 29, 2020. Currently, recreational access to the Oceano Dunes State Vehicular Recreational Area (Oceano Dunes) is limited to non-campground and non-vehicular uses of outdoor areas. The sole motivation for these temporary changes is the need to reduce crowding and disease transmission to address the ongoing COVID-19 public health emergency.

SLO County APCD staff has received several inquiries as to what immediate and long-term impacts may be realized from the temporary closure of the Oceano Dunes. 

The SAG has developed a formal letter and guidance on this topic, and it can be found here

April 1, 2020 Update

In response to the COVID-19 Pandemic and statewide restrictions on non-essential activities, the APCD has closed its office to walk-in traffic and most staff are working remotely. The District's network of permanent air quality monitors continues to operate without interruption, including the CDF, Mesa2, NRP, and Oso Flaco stations near the Oceano Dunes Off Highway Vehicle (OHV) Park. In addition, all of the District's temporary monitors on the Nipomo Mesa continue to operate. The real-time data is still available on our website (www.slocleanair.org), www.airnow.gov, and through all the usual sites and apps that the public uses. AirAware blowing dust alerts will continue.

During the temporary closure of the OHV Park, the extensive network of monitors on the dunes and behind them are well suited to obtain emissions data. Although we are hopeful to see some immediate reductions in particulate emissions, we don’t expect the effects of long-term activity will disappear in a few weeks or months.  

In addition, all mitigation and monitoring projects that State Parks committed to implement in 2020 are still on track. State Parks has already fenced off and the planted the 48-acre foredune project, which is a key element of November's Stipulated Order of Abatement (SOA). They have also completed the 40 acres of temporary dust controls and the 4.2 acres of straw treatment in the back dune area, as required by the SOA. These 90+ acres of new controls are in addition to the existing controls that have been in place since 2018. Sand flux monitors, which measure how much sand is moving during wind events, have already been installed in these mitigation areas, and 15 temporary meteorology stations within the OHV Park are currently being installed. While upcoming in-person meetings have been cancelled, the SAG is continuing its work.

_________________________________________

Over the past 10 years, both the Air Pollution Control District and the OHV Division of State Parks have performed numerous scientific studies to determine the nature, cause and extent of the high particulate matter (PM) concentrations impacting air quality and public health on the Nipomo Mesa. In April 2018, a Stipulated Abatement Order was approved by the APCD Hearing Board. For more information on the numerous studies and all related documents, please click here

Efforts to reduce particulate matter on the Nipomo Mesa are underway through Stipulated Abatement Order 17-01 entered between the San Luis Obispo County APCD and California Department of Parks and Recreation Off-Highway Motor Vehicle Recreation Division (State Parks). The Order was approved by the APCD Hearing Board on April 30, 2018. This stipulated abatement order calls out specific actions to ensure significant reductions in particulate matter are achieved on the Nipomo Mesa over a five-year period. These actions include:

  • Formation of a Scientific Advisory Group (SAG) made up of experts in the fields of dune morphology, native plant cultivation and horticulture, as well as other fields, who will provide assistance to State Parks and the District in developing thoughtful and effective strategies to reduce dust.
  • Development of a Particulate Matter Reduction Plan (Plan) in the Fall of 2018 aimed at achieving state and federal ambient PM10 air quality standards.
  • Public outreach and inclusion in the form of workshops in the Winter/Spring of 2019 to review the draft Work Plan and solicit public comments and participation in review of the of the draft plan and SAG recommendations.
  • Integration of SAG and public comments into the Plan during the Spring of 2019.

An annual Report and Work Plan will be prepared with assistance from the SAG for each year of the five-year term of the Particulate Matter Reduction Plan for the Air Pollution Control Officer’s (APCO) approval. Each report will fulfill the following requirements:

  • Annual reports will review the dust controls implemented over the previous year, and using metrics specified in the approved Plan, will compare acheivements to increments of progress requirements approved in the previous Report.
  • Include increments of progress using tracking metric supplied in the approved Plan.
  • Provide for additional metrics to assess mitigation progress with input from the SAG.
  • Consideration of SAG recommendations for the mitigation techniques proposed in the annual Report.
  • Air quality modeling will be used to estimate the reductions of PM10 concentrations in populated areas due east of the ODSVRA on the Nipomo Mesa.
  • Detailed implementation schedules with deadlines associated with physical deployment of the mitigation, with duration of mitigation and anticipated impacts to emission reductions detailed
  • Methods to assess progress towards emission reductions.

The APCO will determine approvability of the Annual Reports and Work Plans (Reports) through the following process:

  • Draft reports will be submitted by State Parks to the APCO and SAG by August 1 of each year from 2019 through 2022.
  • The SAG will review each annual Report and submit comments to the APCO regarding the proposed control activities and recommendations for modifications to the proposed control activities no later than September 1 of each affective year.
  • After the SAG comments are incorporated, public workshop(s) will be held to review the Draft Work Plan and to receive public comment.
  • Upon conclusion of the public workshop the APCO will either approve the draft Work Plan or return the Work Plan to State Parks with an itemization of specific deficiencies for correction and reconsideration subsequent to the solicitation of public comments.
  • In October of each year from 2019 through 2022, the Hearing Board, upon request by the Chair or any two members, may convene a meeting to receive an informational update on the Report.
