Newport Beach El Segundo June 13th June 14th

Background

 Newport Beach request to the Coastal Commission to

remove fire rings

 Commission staff cited exemption in SCAQMD rules

as justification to deny request

 Large number of fire rings close to where people live,

work, & play

 Wood smoke poses a localized health impact on beach

goers and nearby residents

Agency Positions on Wood Smoke

 California Air Resources Board

  • Wood smoke a serious threat to public health
  • Aggravates lung and heart disease
  • Can cause 10% increase in children's hospital admissions

for respiratory symptoms  U.S. Environmental Protection Agency

  • Wood smoke can affect everyone

 Children, persons with existing health conditions most vulnerable

 Health risks can be reduced by switching to gaseous fuels

PM Health Guidance

 National Ambient Air Quality Standards for PM2.5:

 Annual Average: 12 mg/m3  24 Hour Average: 35 mg/m3

 Guidance for Public Health Officials for Wildfire Smoke

 Recommended protective measures based upon shorter term

PM exposure

 Includes Time frames as short as 1 to 3 hours

for both PM2.5 and PM10:

 89 - 138 mg/m3 - Unhealthy for Sensitive Groups (USG)  139 - 351 mg/m3 - Unhealthy – “consider canceling public events, based on public health and travel considerations”  352 - 526 mg/m3 - Very Unhealthy

Beach Fire Pit Emissions

 Assessed the emissions of a single fire ring for

  • ne evening

 One fire event assumed to burn 2 bundles of

wood (approx. 32 lbs total)

 Assumed CARB fireplace emission factor  Compared emissions to that of an average on-

road 2013 Heavy Duty Diesel Vehicle (HDDV)  One fire pit in one evening estimated to

emit as much PM2.5 as one Heavy-Duty Diesel Truck driving 564 miles

SCAQMD Monitoring Studies

 Purpose

 Assess potential for human exposure to wood smoke

from beach fires  Approach

 Deploy a combination of monitoring technologies and

sampling strategies  Other Considerations

 Shifting meteorology, variable activity levels, technology

limitations

Gradient Surveys

Objective:

Assess the PM impacts of the Beach Fires at multiple locations downwind over the course of an evening

Methods:

TSI Inc. DustTrak DRX – Measures PM1, PM2.5, PM10

  • n a second-by-second basis

Advantages: small, portable, high time resolution, good survey tool for relative measurements Limitations: not certified to federal reference method criteria. A drying inlet implemented to remove humidity effects

Methods:

E-BAM – Measures PM2.5 on an hourly basis Advantages: portable, low power, same measurement principle as a Federal Equivalent Method Limitations: less accurate at low levels Aethalometer – Measures Black Carbon, an indicator of combustion, on a continuous basis Condensation Particle Counter (CPC) - Measures Ultrafine particles, indicative of nearby sources of combustion

Filter analysis

Corona del Mar (3/30 to 4/19), Huntington Beach (4/24 to current)

  • PM2.5 Mass (24 hour average) – Daily Samples
  • All below 12.5 ug/m3, under the 24 hour NAAQS level (35 ug/m3)
  • One day nearly 40 ug/m3, day had very high gusty winds
  • PM10 mass (4 hour sample, 4/6) - One Sample Only
  • Sample collected from 5 to 9pm with burning activity shown to

have PM10 mass concentration of 95 ug/m3.

  • 30% higher concentration than sample collected from 1 to 5pm
  • Elevated levels of Potassium, an indicator for wood smoke

Preliminary Air Monitoring Conclusions

  • Beach fire activity is impacting PM2.5 levels at the

beach and extending into neighboring communities

  • Concentrations can be over 10 times background levels

for short periods of time in beach parking areas, up to 3 times background at residential locations

  • 1-hour average PM concentrations can exceed public

health guidance levels

  • Some measurements are higher than observed across

the Basin over a whole year

Proposed Rule 444 Amendments

 Initial proposal prohibited all beach burning (March 21, 2013)  Revised Language released on June 6, 2013

 Provision for cities to remove rings if they are declared to be a public nuisance  All rings more than 700 feet from residences are allowed  Spacing requirements if within 700 feet

 100 feet apart, or  50 feet apart if 15 or less pits in a city

 No-burn days if high particulate levels are forecast in that coastal area  Only applicable to pits on the sand

slide-14
SLIDE 14

6/14/2013 14

Impacts of Revised Proposal

 Provides additional authority and discretion to cities to remove fire rings through a nuisance declaration  If a city does not make a nuisance declaration

 All fire rings outside 700 ft. residential buffer zone are still allowed at any spacing  Fire rings within 700 ft. zone subject to spacing requirements (50 or 100 ft.)  Burning is subject to coastal “no-burn” days (once in last 3 years)

 Net effect:

 Huntington State Beach: ~30 rings would be moved or spaced out  Doheny State Beach: ~20 of 60 rings would be moved or spaced out  Aliso, San Clemente: slight shifting of rings would meet requirements

Next steps

  • Seek public input
  • Continue field sampling as necessary
  • Continue to report findings to public as they

become available

  • Continue to work with potentially impacted cities

and state parks

  • Demonstration project for propane and natural gas

beach fire options

  • Public Hearing scheduled for July 12, 2013
