Introduction
1.0 INTRODUCTION
Pursuant to Section 21 081.6 of the Public Resources Code and the California Environmental Quality Act (CEQA) Guidelines Section 15097, public agencies are required to adopt a monitoring or reporting program to assure that the mitigation measures and revisions identified in the Environmental Impact Report (EIR) are implemented. As stated in Section 21 081.6 of the Public Resources Code:
" ... tlze public agency shall adopt a reporting or monitoring program for the changes to the project which it has adopted, or made a condition of project approval, in order to mitigate or avoid significant effects on the environment. " Pursuant to Section 21081 (a) of the Public Resources Code, findings must be adopted by the decision maker coincidental to certification of the EIR. The Mitigation Monitoring and Reporting Program (MMRP) must be adopted when making the findings (at the time of approval of the project).
As defined in the CEQA Guidelines, Section 15097, "reporting" is suited to projects that have readily measurable or quantitative measures or which already involve regular review. "Monitoring" is suited to projects with complex mitigation measures, such as wetland restoration or archaeological protection, which may exceed the expertise of the local agency to oversee, are expected to be implemented over a period of time, or require careful implementation to assure compliance. Both reporting and monitoring would be applicable to the proposed project.
The Initial Study/Mitigated Negative Declaration prepared for Remington Condominiums (SCH #2006081041) provided an analysis of the environmental effects resulting from construction and operation of the project. A thorough scientific and engineering evaluation of each alternative was undertaken in compliance with CEQA, including the identification of measures designed to avoid or substantially reduce the potential adverse effects of each alternative.
1.1 DESCRIPTION OF PROPOSED PROJECT
The proposed project includes the development ofa 272-unit condominium development and associated amenities on approximately 19 acres. Within the City of Calexico, these parcels are zoned Residential Apartment and Residential Single Family. The project proposes a zone change to Residential Condominium and will be constructed in two phases.
1.2 MITIGATION MATRIX
In order to sufficiently track and document the status of mitigation measures, a mitigation matrix has been prepared and includes the following components:
• Mitigation measure number
• Mitigation measure (text)
• Implementation Action
• Monitoring Method
• Responsible Monitoring Party
• Monitoring Phase
• Verification/Approval Party
• Mitigation Measure Implemented? (YIN, and date)
• Documentation Location (Monitoring Record)
L """''":l Remington Condominiums rLI.' Mi/iga/ion Monitoring and Reporting Program 1- 1 City of Calexico
October 2005
Introduction
Mitigation measure timing of verification has been apportioned into several specific timing increments.
Of these, the most common are:
1. Prior to issuance of grading permit
2. Prior to issuance of building permit(s)
3. During construction
4. Prior to issuance of certificate of use and occupancy
1.3 MITIGATION MONITORING PROCEDURES
The City of Calexico Planning Department is the designated lead agency for the Remington Condominiums MMRP. The City is responsible for review of all monitoring reports, enforcement actions, and document disposition. The City will rely on information provided by the monitors (e.g. archaeologists, biologists, etc.) as accurate and up-to-date and will field check mitigation measure status as required.
1.3.1 In-Field Monitoring
Project monitors shall exercise caution and professional practices at all times when monitoring construction. Protective wear (hard hats, glasses, etc.) shall be worn at all times in construction areas.
Injuries shall be reported immediately to the mitigation monitor.
1.3.2 Coordination with Contractors
The construction manager/superintendent is responsible for coordination of contractors, and is also responsible for contractor completion of required measures in accordance with the provisions of this program.
1.3.3 Recognized Experts
The use of recognized experts as a component of the monitoring team is required to ensure compliance with scientific and engineering based mitigation measures. While the mitigation monitoring team recognized experts assess compliance with required mitigation measures, consultation with the City of Calexico planning staff shall take place in the event of a dispute.
1.3.4 Arbitration/Dispute Resolution
If the mitigation monitor has identified an action which, in the opinion of the monitor, has not been implemented or has not been implemented correctly, the problem will be brought to the attention of the City of Calexico for resolution. If the problem cannot be satisfactorily resolved by City staff, it will be brought before the Planning Director or designee for resolution. The City will have the authority to issue stop work orders until the dispute is resolved.
1.3.5 Enforcement
Agencies may enforce conditions of approval through their existing police power, using stop work orders, fines, infraction citations, loss of entitlements, refusal to issue building permits or certificates of use and occupancy or, in some cases, notice of violation for tax purposes. Criminal misdemeanor sanctions could be available where the agency has adopted an ordinance requiring compliance with the monitoring program, similar to the provision in many zoning ordinances which affirm the enforcement power to bring suit against violators of the ordinances provisions.

EXISTING CONDITIONS
METEOROLOGY/CLIMATE
The proposed project site is located in the Imperial County portion of the Salton Sea Air Basin (SSAB). The SSAB was part of the Southeast Desert Air Basin (SEDAB) until May 1996. The project site is in the hottest and driest part of California. The climate is characterized by hot, dry summers and relatively mild winters. Rainfall is scant in all seasons, so differences between the seasons are marked principally by differences in temperature. Average annual precipitation in the project area averages 3 inches per year.
Seasonal temperature differences in the basin are large, confirming the absence of marine influences due to the blocking action of the mountains to the west. Average monthly maximum temperatures in the project vicinity range from 109°F in July to 69°F in January. Average monthly minima range from about 38°F in January to about 75°F in July.
During much of the year, California is covered by a moderately intense high pressure system. In winter, the Pacific High retreats to the south, so that frontal systems from the North Pacific can move onto the California coast. On average, 20 to 30 frontal systems pass through California each winter. The first front usually arrives around the middle of October, and the average period of frontal activity is five to six months. Most of these systems are relatively weak by the time they reach the SSAB, however, and they become more diffuse as they move southeastward.
Spring is a transition season between the winter period of frontal activity and the generally dry summer; some precipitation continues during the early part of the season.
During the summer, the Paci fie High is well developed to the west of California, and a thermal trough overlies the SSAB. The intensity and orientation of the trough varies from day to day.
While the rugged mountainous country prevents a normal circulation, the influence of the trough does permit some inter-basin exchange with coastal locations through the passes. Summer is also the season with occasional moisture influx from the Gulfs of Mexico or California which causes isolated thundershowers and flash flooding (the summer "monsoon").
Fall is the transition period from the hot summer back to the season of frontal activity, but it is still very dry and temperatures are still mild.
Desert regions tend to be windy, since little friction is generated between the moving air and the low, sparse vegetation cover. In addition, the rapid daytime heating of the lower air over the desert surface leads to convection activity. The exchange between lower and upper air layers tends to accelerate surface winds during the warm part of the day when convection is at a maximum. During winter, however, the rapid cooling in the surface layers at night retards this exchange of momentum, and the result is often a high frequency of calm winds, especially at night.

During all seasons, the prevailing wind direction across the project site is predominantly from the west. Periodic winds from the south blow into Calexico from Mexicali. A high population density and less strict pollution controls in Mexico result in elevated levels of air pollution in Calexico during periods of cross-border transport. However, the frequency and intensity of any air pollution episodes during south to north wind events appears to have dramatically diminished in Calexico during the last five years.
The mixing depth, i.e., the height available for dispersion of airborne pollutants emitted near the surface, is limited by the occurrence of temperature inversions. A temperature inversion is a layer of air in which the temperature increases with height. The temperature inversion conditions of the SSAB are quite different from those of the coastal regions of California. In coastal environments, warm, subsiding air aloft creates a lid above the shallow marine layer at the surface. The base of this subsidence inversion is perhaps 1,500 feet above the surface in coastal portions of the Los Angeles Basin. When a subsidence inversion exists over the desert, the height of the inversion base lies some 6,000 to 8,000 feet above the surface.
Nighttime surface inversions in the desert are common, especially during the cooler months.
Mixing heights are predominantly 1,000 feet or less. These inversions are caused by nighttime radiational cooling of the land surface in contact with overlying air that cools more slowly. They tend to be destroyed early in the day in summer, due to intense solar radiation and heating of the land surface. In winter, however, these radiation inversions tend to persist until mid-morning, limiting mixing in the lower atmosphere to heights of 200 to 2,000 feet above the surface. "Nuisance" air quality problems in the Imperial Valley, such as dust near mining operations or odors near feedlots or wastewater plants, occur mainly late at night or early in the morning when winds are nearly calm and such radiation inversions are strongest.

Ambient Air Quality Standards (AAQS)
In order to analyze the air quality impact of operations at the proposed Remington condominium development, that impact, together with baseline air quality levels, must be compared to the applicable ambient air quality standards. These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect that segment of the public most susceptible to respiratory distress or infection such as asthmatics, the elderly, the very young, people weak from other disease or illness, and persons engaged in heavy work or exercise, called sensitive receptors. Healthy adults can tolerate periodic exposure to air pollution levels somewhat above these standards before adverse health effects are observed. Recent research has shown, however, that chronic exposure to ozone even at the federal clean air standard level can create unhealthful reactions through pulmonary distress. Just meeting clean air standards may therefore ultimately not be enough to protect human health such that an additional margin of safety may need to be created to achieve all clean air objectives.
The Clean Air Act Amendments (CAAA) of 1970 established national AAQS with states retaining the option to adopt more stringent standards or to include other pollution species.
Because California already had standards in existence before the federal AAQS were established, and because of unique meteorological problems in California, there is considerable diversity between state and federal standards. California Ambient Air Quality Standards (CAAQS) and National Ambient Air Quality Standards (NAAQS) for the criteria air pollutants are listed in Table I. Health effects of these criteria pollutants are described in Table 2.
The entries in Table I include the recently (I 997) adopted federal standards for chronic (8-hour) ozone exposure or for ultra-small diameter particulate matter of 2.5 microns or less in diameter (called "PM-2.5"). The Environmental Protection Agency's (EPA) authority to adopt such standards was subsequently challenged. In a unanimous decision published at the end of February 200 I, the Court ruled the EPA did have authority to promulgate standards without specific congressional authority, and that a cost-benefit analysis was not required for healthbased standards. The Court also ruled, however, that there was an attainment schedule inconsistency between "old" and "new" standards. This inconsistency was resolved through a consent decree signed by the EPA in 2002. EPA has designated Imperial County as a "marginal" non-attainment area for the 8-hour ozone standard. The former non-attainment designation for the one-hour standard was revoked when the 8-hour standard took full effect in 2005.

Analysis of the most current data on the health effects of inhalation of fine particulate matter prompted the California Air Resources Board (ARB) to recommend adoption of the statewide PM-2.5 standard that is more stringent than the federal standard. This standard was adopted on June 20, 2002. The state standard became enforceable in 2003 when it was incorporated into the California Health and Safety Code. There are currently no State PM-2.5 standard attainment deadlines. Although the Imperial Valley experiences high dust levels due to very dry soils, only a small fraction of earthen material is in the PM-2.5 size range. PM-2.5 levels are therefore not as frequently or severely above standards as are PM-10 concentrations.
Because of the strong evidence that chronic ozone exposure is more harmful than short-term hourly levels, the ARB has adopted a new ozone standard. The new standard mirrors the federal longer-term (8 hour) exposure limit. The California 8-hour ozone standard is slightly more stringent than the federal standard. It does not have a specific attainment deadline, but only that continued progress toward attainment must be demonstrated.
BASELINE AIR QUALITY
Existing levels of ambient air quality and historical trends and projections in the project area are best documented from measurements made by the Imperial County Air Pollution Control District (ICAPCD). The closest air monitoring station to the project site with the most complete data record is located in Calexico at the "Ethel Street" monitor. From this data resource, one can readily infer that baseline air quality levels near the project site are occasionally unhealthful, but there are some encouraging signs that the air is slowly, but surely, getting better. Attainment may still be years away, but the frequency and magnitude of air pollution episodes, especially those considered unhealthy for all people, has dropped considerably in the last decade.
Table 3 summarizes the last five years of published monitoring data from the Ethel Street air monitoring station. PM- I 0 levels around Calexico exceed the state standard on a large number of days. Several of the PM- I 0 episodes exceed the federal standard. It had been argued by the U.S. Environmental Protection Agency that most violations of federal PM-10 standards occur due to cross-border dust transport or during high wind episodes, and therefore Imperial County should not be considered a non-attainment area for the PM-I 0 standard. This conclusion was not upheld by federal courts which agreed that the non-attainment designation and any associated planning requirements should remain in place.
The Salton Sea Air Basin stands as non-attainment for ozone. Summer ozone levels routinely exceed standards, particularly the more stringent State one-hour standard. However, since 2002, there has been a dramatic improvement in ozone air quality. Since 2002, there has been an average of only three days above the state ozone standard, and there have been no violations of the federal one-hour, and only one violation of the federal eight-hour standard in three years.
Any air-shed that does not exceed federal standards more than three times in three years is considered to be in attainment. The Calexico area, based upon monitoring data from the Ethel Street monitor, did meet federal clean air criteria for ozone from 2002-2004.

The federal 8-hour CO standard was exceeded five times in 2002-04 (no more than three violations is required for attainment).
However, there was only one violation in the last two years of published data.
Air basins where ambient air quality standards are exceeded are called "non-attainment" areas. If standards are met, they are designated as "attainment" areas. If there is inadequate or inconclusive data to make a definitive attainment designation, they are considered "unclassified." Federal "non-attainment" areas are considered extreme, serious or moderate as a function of deviation from standards. The current attainment designations for the project area are as follows:

Revised federal clean air standards for particulate matter were adopted by EPA on September 21, 2006. A more stringent 24-hour standard for PM-2.5 was adopted, and the PM-I 0 standard was revoked. A new class of "coarse particulates" (PM-10 minus PM-2.5) was developed, but coarse particulate standards may not be enforced in more rural areas. Revisions to federal attainment designations related to particulate matter will therefore be forthcoming.

STANDARDS OF SIGNIFICANCE
Many air quality impacts from dispersed mobile sources, i.e., the dominant pollution generators affecting the proposed project, often occur hours later and miles away after photochemical processes have converted primary exhaust pollutants into secondary contaminants such as ozone.
The incremental regional air quality impact of an individual source is generally immeasurably small. The ICAPCD has therefore developed suggested significance thresholds based on the volume of pollution emitted rather than on actual ambient air quality because the direct air quality impact of a project is not quantifiable on a regional scale. The ICAPCD CEQA Air Quality Handbook (2005) states that any projects in Imperial County with daily emissions that exceed any of the following thresholds should be considered as having an individually and cumulatively significant air quality impact:
Pollutant Threshold
ROG 55
NOx 55
co 550
PM-10 150
SOx 150
Projects that do not exceed the above thresholds are considered Tier I projects. If the projectrelated emissions are below the above thresholds, and if standard mitigation measures are implemented as per the ICAPCD CEQA Handbook, then emissions impact may be considered less-than-significant, and a mitigated negative declaration (MND) is considered the appropriate form of CEQA clearance. If these thresholds are exceeded, the project is considered a Tier II project, and an EIR is considered to be required.
CONSTRUCTION IMPACTS
Construction activities will generate dust from surface disturbance and equipment exhaust from heavy off-road equipment. The URBEMIS2002 model indicates that the maximum simultaneous project disturbance size during grading will be 4.2 acres. Emissions of particulates (PM-I 0) from construction activity soil disturbance were evaluated using factors in the SCAQMD CEQA Handbook. Fugitive dust particulate matter is calculated as follows with the use of minimum dust control:
PM-I 0 = 4.2 acres X 26.4 pound/acre/day c 111 pound/day Even with only minimum (once-daily watering) dust control and with maximum daily simultaneous disturbance, the daily PM-I 0 significance threshold of 150 pounds per day will not be exceeded. However, ICAPCD rules require use of best available control measures (BACMs) X U02J5 1 Caty. or C&lrnco\l2957 R<rNngtcnlll QAUSMND·Fin.tl\CommenuOnllr>l\ll\espondm&Kespoi>ses'JINu!ftroo•~ lll Remington Condommh•n·AQtllDRccnvn<111<doc 9 for all construction projects in its adoption of Regulation VI 11. With mandatory use of BACMs, the accepted fugitive dust (PM-I 0) emissions factor is reduced to I 0.0 pounds per acre per day (California Air Resources Board). Project-related construction activity PM-10 emissions will be reduced to 42 pounds per day as a worst-case condition, or 28 percent of the adopted significance threshold of 150 pounds per day.
The ICAPCD CEQA Air Quality Handbook contains a number of standard dust control measures that should be implemented at all construction sites. For sites larger than four (4) acres, such as the Remington Condominiums, use of additional discretionary measures beyond the standard dust control program is recommended. The menu of standard measures and of candidate discretionary measures is included in the mitigation discussion to support a finding of a lessthan-significant impact. The ICAPCD CEQA Handbook does not reflect the passage of Regulation VIII in its present form. Regulation VIII has converted many of the dust control recommendations to mandatory implementation. Preparation and approval of a formal dust control plan is required fo r any substantial construction projects. The language of "should be implemented" as part of CEQA process mitigation has been replaced with "must be implemented" as part of a rule and regulation. Mandatory compliance with Regulation VIII will further strengthen the conclusion that dust emissions during project construction will be maintained at a less-than-significant level.
In addition to particulate matter, construction activities will generate exhaust emissions from onsite equipment, (mainly NOx from diesel equipment), and reactive organic gases (ROG) from application of paints and coatings. ROG and NOx are precursors to regional ozone formation. If temporary construction activity emissions are generated in substantial amounts during the warmer months (the "smog season"), they could be considered to have a significant impact.
Exhaust emissions from typical construction equipment during site clearing and grading activities were calculated using the California ARB URBEMIS2002 computer model. Emissions were calculated for an equipment "fleet" as follows:
Grading Construction Paving
Grader Grader Paver
Dozer Forklift Roller
Water Pull Backhoes (2) Water Truck
Scrapers (2)
The URBEMIS2002 computer model results for construction equipment emissions, plus the fugitive PM-I 0 sources, are as follows:

The 272 condominium unit project will create around 2, 176 trips per day. The regional emissions from this level of trip generation were calculated using the California Air Resources Board URBEMIS2002 computer model. The results are shows in Table 4. Maximum daily emissions from project traffic, plus minor "area source" emissions such as personal care or cleaning products, paints, and solvents, natural gas combustion, etc., are no more than 72 percent of the significance threshold. Regional project-related air quality impacts are therefore individually less-than-significant. Project-related traffic will not cause any intersection to operate at a congested level of service, and the total CO burden is less than the ICAPCD threshold. With mitigation, project vicinity intersections carrying combined existing plus project plus cumulative area growth traffic will continue to operate at acceptable levels. The potential for any local CO "hot spot" is minimal. A CO impact screening analysis was not conducted.
Because of the role of general growth in contributing to the regional air pollution burden, the CEQA Handbook contains a number of standard measures to minimize cumulative air quality impacts from all regional growth. Those standard measures applicable to the proposed project are included in the mitigation discussion.
Air quality effects from rapid Calexico area growth have been identified by ICAPCD staff as a serious local and regional air quality concern, particularly because of the additional influence of cross-border transport of air pollution. However, that rate of growth has been incorporated into regional plans for mobility, air quality and essential services such that projected levels of growth can be accommodated while still meeting most quality of life goals. The Southern California Association of Governments (SCAG) forecasts the following growth for Calexico between 2005 and 2010:
Analysis Year Pooulation Housin2 Employment
2005 38,233 9,293 10,622
2010 48,720 12,865 16,521

County Growth +23,953 +9,608 +15,673
Calexico Share 44% 37% 38%
The City of Calexico is forecast to accommodate 44 percent of all new population in Imperial County in the current 5-year planning interval. An increase of 3,572 dwelling units is forecast.
The Remington Condominium project would absorb 7.6% of Calexico's forecast growth. The project's scope is such that it is consistent with growth forecasts that are included in regional air quality planning. However, the current "Imperial County Air Quality Attainment Plan (AQAP) for Ozone" is based on the City's General Plan growth forecasts developed in 1992. Updated growth projections, including Remington Condominiums, far exceed the pace of previously planned growth included in the AQAP. The cumulative air quality impact from all growth is considered significant and not fully mitigable due to conflicts with the adopted AQAP.

The City of Calexico requires implementation of all reasonably available control measures for both construction and operation. The matrix of reasonably available measures (RACMs) derived from Chapter 7 of the JCAPCD CEQA Air Quality Handbook (2005) is detailed below.
Subsequent to the release of the CEQA Handbook, The Board of Supervisors adopted a countywide dust control rule (Regulation VIII) that requires use of best available control measures (BACMs) on construction projects. Use of BACMs has a more beneficial PM-10 reduction than does use of RACMs. All projects must use measures that limit visible dust emissions (VDE) to less than twenty percent opacity, and establish a stabilized surface on any previously disturbed sites. For projects exceeding ten acres, a dust control plan must be submitted and approved by JCAPCD. Failure to comply with an approved plan subjects a construction contractor to possible fines and a cease and desist order to chronic or willful violations.
CONSTRUCTION EQUIPMENT AND FUGITIVE PM-10 MITIGATION MEASURES Standard Mitigation Measures for Construction Equipment:
a. Maintain all construction equipment in proper tune according to manufacturer's specifications.
b. Fuel all off-road and portable diesel-powered equipment, including but not limited to bulldozers, graders, cranes, loaders, scrapers, backhoes, generator sets, compressors, auxiliary power units, with ARB-certified motor vehicle diesel fuel (non-taxed version suitable for off-road).
c. Maximize to the extent feasible, the use of diesel construction equipment meeting the ARB's 1996 or newer certification standard for off-road heavy-duty diesel engines. d. Install diesel oxidation catalysts (DOC), catalyzed diesel particulate filters (CDPF) or other District-approved emission reduction retrofit devices.
Standard Mitigation Measures for Fugitive PM-IO Control:
a. The entire site shall be pre-watered for 48 hours prior to clearing and grubbing. b. Reduce the amount of the disturbed area where possible. c. Water at least twice daily or otherwise stabilize all active construction areas. d. All dirt stock-pile areas should be sprayed daily as needed.

Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites. f. Haul trucks shall cover loads or maintain at least 6 inches of freeboard when traveling on public roads.
g. Pre-moisten, prior to transport, import and export materials that have a silt content of 5% or greater. Water all materials with a silt content of 5% or greater with a spray bar, or cover trucks hauling dirt, sand, or loose materials. Empty trucks and trucks carrying asphalt material are excluded from this requirement.
h. Sweep streets at the end of each day if visible soil material is carried onto streets, or wash off trucks and equipment leaving the site.
BACM Mitigation Measures for Fugitive PM-I 0 Control:
a. Use of water trucks or sprinkler system in sufficient quantities to prevent airborne dust from leaving the site. When wind speeds exceed 15 mph, the operators shall increase watering frequency.
b. Apply chemical soil stabilizers, or apply water to form and maintain a crust on inactive construction areas (disturbed lands within construction projects that are unused for at least four consecutive days).
c. Apply non-toxic binders (e.g. latex acrylic copolymer) to exposed areas after cut and fill operations, and hydroseed areas.
d. Plant vegetative ground cover in disturbed areas as soon as possible and where feasible. e. Cover or apply water or chemical suppressants to form and maintain a crust on inactive storage piles.
f. All roadways, driveways, sidewalks, etc. to be paved should be completed as soon as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.
g. Vehicle speed for all construction vehicles shall not exceed J 5 mph on any unpaved surface at the construction site.
h. Install wheel washers, rumble gates, provide a gravel pad or pave the area where vehicles enter and exit unpaved roads onto streets, or wash off trucks and equipment leaving the site.

RESIDENTIAL PROJECTS
Standard Site Design Measures:
a. Link cul-de-sacs and dead-end streets to encourage pedestrian and bicycle travel; b. Allocate easements or land dedications for bikeways and pedestrian walkways; and c. Provide continuous sidewalks separated from the roadway by landscaping and on-street parking. Adequate lighting for sidewalks must be provided, along with crosswalks at intersections.
Standard energy Efficiency Measures:
a. Increase the building energy efficiency rating by I 0% above what is required by Title 24 requirements. This can be accomplished in a number of ways (increasing attic, wall or floor insulation, etc.).
With implementation of the above measures, project-related air quality impacts will be reduced to an individually less-than-significant level. Because of the cumulative air quality impact from all Calexico area growth, especially a rate of growth that has not been adequately incorporated into the County's air quality plan for ozone, cumulative impacts are considered significant and will not be reduced to less-than-significant by implementation of the above mitigation measures.
