71 the potential to result in varying degrees of temporary ground vibration, depending on the specific construction activities and equipment used. Ground vibration levels associated with various types of construction equipment are summarized on Table 11-4. Based on the representative vibration levels presented for various construction equipment types, it is possible to estimate the potential Project construction vibration levels using the following vibration assessment methods defined by the FTA. To describe the human response (annoyance) associated with vibration impacts the FTA provides the following equation: PPVequip = PPVref x (25/D)1.5
TABLE 11-4: VIBRATION SOURCE LEVELS FOR CONSTRUCTION EQUIPMENT Equipment PPV (in/sec)
at 25 feet
Small bulldozer 0.003
Jackhammer 0.035
Loaded Trucks 0.076
Large bulldozer 0.089
Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual Using the vibration source level of construction equipment provided on Table 11-4 and the construction vibration assessment methodology published by the FTA, it is possible to estimate the Project vibration impacts. Table 11-5 presents the expected Project related vibration levels at the nearby receiver locations. At distances ranging from 51 to 5,046 feet from the Project construction activities, construction vibration velocity levels are estimated to range from less than 0.01 to 0.03 in/sec PPV. Based on maximum acceptable continuous vibration threshold of

0.30 PPV (in/sec), the typical Project construction vibration levels will satisfy the building damage thresholds at all receiver locations. Therefore, the Project-related vibration impacts are considered less than significant during the construction activities at the Project site.

In addition, the typical construction vibration levels at the nearest sensitive receiver locations are unlikely to be sustained during the entire construction period but will occur rather only during the times that heavy construction equipment is operating adjacent to the Project site boundaries.

73 12 ON-SITE AIRCRAFT NOISE IMPACTS
An on-site exterior aircraft noise impact analysis has been completed to determine the noise exposure levels that would result from adjacent JFTB Los Alamitos aircraft noise sources in the Project study area, and to identify potential noise abatement measures for the proposed Project that would achieve acceptable Project noise levels.

The JFTB Los Alamitos is located adjacent to, and northwest of the Project. Exhibit 3-B shows the Project site in relation to the airport’s projected noise level contour boundaries, as provided by the 2020 Noise Assessment for Los Alamitos Airfield, Joint Forces Training Base Los Alamitos (18).

As shown on Exhibit 12-A, the northwestern portion of the Project site would locate residential uses between the 60 and 65 dBA CNEL noise level contours of JFTB Los Alamitos. The compatibility criteria (16), shown on Exhibit 3-D, indicates residential land uses exposed to noise levels less than 60 dBA CNEL are “normally consistent”, less than 65 dBA CNEL are considered “conditionally consistent” which requires an acoustical analysis to ensure that the interior CNEL does not exceed 45 dBA CNEL. The ALEUP does not require any additional considerations for exterior locations exposed to noise levels below 70 dBA CNEL.

As discussed in Section 7.2.1, typical building construction will provide a Noise Reduction (NR) of approximately 12 dBA with "windows open" and a minimum 25 dBA noise reduction with "windows closed." Based on future JFTB Los Alamitos aircraft noise levels ranging from 60 to 65 dBA CNEL, interior noise levels would range from 35 dBA to 40 dBA CNEL. This noise level analysis shows that the 45 dBA CNEL interior noise standard can be satisfied using standard construction and complying with statutory and regulatory noise requirements for all residential units exposed to aircraft noise from JFTB Los Alamitos. Therefore, the Project would not expose people residing or working in the project area to excessive noise levels from airport or aircraft operations, and impacts would be less than significant.

4 REFRIGERANT CHARGE ADJUSTMENTS
Liquid Line Size Puron Charge oz/ft
3/8 0.60
(Factory charge for lineset = 9 oz)
5/16 0.40
1/4 0.27
Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line. The factory charge for 3/8” lineset 9 oz. When using other length or diameter liquid lines, charge adjustments are required per the chart above.

Charging Formula:
[(Lineset oz/ft x total length) – (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4“ liquid line. What charge adjustment is required? Formula: (.27 oz/ft x 15ft) – (9 oz) = (-4.95) oz.

Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment? Formula: (.40 oz/ft. x 45ft) – (9 oz.) = 9 oz.

Net result is to add 9 oz of refrigerant to the system

LONG LINE APPLICATIONS
An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.

For Air Conditioner systems, the chart below shows when an application is considered Long Line.
