• CONFORMITY DETERMINATION
FOR
RANCHO PALOS VERDES
FEASIBILITY STUDY
The Clean Air Act (CAA), as amended in 1990, specifies in Section 176(a) that no department,
agency, or instrumentality of the Federal Government shall engage, in, support in any way, or
provide financial assistance for, license or permit, or approve, any activity which does not
conform to an implementation plan after it has been approved or promulgated under Section 110
of the Act. "Conformity" is defined in Section 176(c) of the CAA as conformity to the State
Implementation Plan's (SIPs) purpose of eliminating or reducing the severity and number of
violations of the national Ambient Air Quality Standards (NAAQS) while achieving expeditious
attainment of such standards.
Air quality standards in the feasibility study area is under the jurisdiction of the South Coast Air
Quality Management District (SCAQMD). In 1995, SCAQMD measured pollutant
concentrations from all their monitoring stations within their jurisdiction. Pollutant concentrations
exceeded federal and state standards for ozone, carbon monoxide, and particulate matter, and the
state standard for sulfate. Standards for nitrogen dioxide, sulfur dioxide, and lead were not
exceeded.
Calculations of the emissions associated with initial constructions and future operations and
imaintenance activities were performed using guidance f om SCAQMD's 1993 California
Environmental Quality Act (CEQA) Air Quality handbook, and following federal Applicability
criteria for non-attainment areas.
The analysis in this Appendix demonstrates that the activities associated with this project are
below de minimis levels prescribed in 40 CFR 93.153(b), and is, therefore, exempt from
demonstrating conformity to State or Federal Implementation Plans.

EMISSION CALCULATIONS
Construction activities associated with the construction of the dike for the Palos Verdes
Feasibility Study is expected to take 1.5 years. Operations and Maintenance activities are
expected to take one year. The emissions calculations in this Appendix uses the equipment lists
and hours of use identified in the Cost Engineering Appendix(Volume II) and is performed using
guidance from SCAQMD's 1993 California Environmental Quality Act (CEQA) Air Quality
handbook(SCAQMD 1993).
I. OFFSHORE DIKE (400' from shore) CONSTRUCTION-Island Rock Source
EMISSIONS =F x G x H (in lbs./day)
(Formula from Table A9-8 of SCAQMD 1993 where F =no. of equipment; G= daily hrs. of
operation/day;H=time specific emission factor in lbs./hr. from Table A9-8A and B)
A. Loader's Emissions
CO Emissions =3 x 8 x .57= 13.7 lbs./day
ROC Emissions= 3 x 8 x .002 = 0.1 lbs./day
NOx Emissions =3 x 8 x .01 = 0.24 lbs./day
SOx Emissions =3 x 8 x .0005 = .01 lbs./day
PM10 Emissions=3 x 8 x ..00005 = .001 lbs./day 11111:
B. Crane's Emissions
CO Emissions = 8x 8 x .009 = .6 lbs./day
ROC.nisi Jlls G 8 x 8 x .0'33 = .2 ibs./daJ
NOx Emissions = 8 x 8 x .023 = 1.5 lbs./day
SOx Emissions = 8 x 8 x .002 = .13 lbs./day
PM10 Emissions= 8 x 8 x .0015 = .1 lbs./day
G-2
C. Tug Boat's Emissions
► 10 tug boat round trips/day
► 30 miles from Rancho Palos Verdes Peninsula to Catalina Island
► 10 round trips/day x 30 miles=300 miles traveled/ day (i.e., Vehicle Miles
Traveled [VMTs])
1. Tug Emissions=VMTs (in miles/day)x Emission Factor* ([grams/mile]x
[1 lb./454 grams])=Emissions in lbs./day
CO Emissions=300 x(27,000/6000)x (19.49/454) = 58.0 lbs./day
ROC Emissions= 300 x(27,000/6000)x(2.36/454) = 7.0 lbs./day
NOx Emissions = 300 x (27,000/6000)x(5.07/454) = 15.1 lbs./day
PM10 Exhaust Emissions =300 x(27,000/6000)x (.22/454) = .65 lbs./day
2. Cold Start/Hot Start Truck Emissions=#Trucks started x Emission Factor
Cold Start: 10 tug boat cold starts
CO Emissions= 10 x(27,000/6000)x(28.65/454)=2.8 lbs./day
ROC Emissions= 10 x(27,000/6000)x(1.82/454) =0.18 lbs./day
NOx Emissions= 10 x(27,000/6000)x(1.98/454) =0.18 lbs./day
• Hot Start:20 tug boat hot starts
CO Emissions=20 x(27,000/6000)x(3.12/454)=0.62 lbs./day
ROC Emissions=20 x(27,000/6000)x(0.45/454)=0.09 lbs./day
NOx Emissions=20 x(27,000/6000)x(.93/454)=0.18 lbs./day
*Emission factor for tug boats was based on the formula:
(weight of 330 hp diesel tug boat/weight of 6000 lb heavy duty truck)x
emission factor for heavy-duty truck at 10 mph[from Table A9-51(-7 of SCAQMD 1993]
For example: Tug Emissions Factor for COQ(27,000lbs/6000l s) x(19.49/454)= 0.19
(The formula is based on coordination between SCAQMD and USACE for the Air Quality
analysis performed for<<USACE 199X: Appendix XX»)
