CEIE - Coord - Part 1 of 2 Air Quality Comments General Construction. 1. Any portable equipment powered by an internal combustion engine with a rated horsepower of 50 bhp or greater used for this project must be registered in the California State-wide Portable Equipment Registration Program or have a valid Santa Barbara County Air Pollution Control District Permit to Operate. Examples of such equipment are portable generators, compressors and light-carts. 2. Offroad construction equipment must be compliant with all Federal, state and local regulations. 3. Unconfined abrasive blast materials must be certified by the California Air Resources Board. Certification statement must be on abrasive container and abrasive must be approved through the HazMat Tracking Activity/Hazmart. POC: , 08/20/2026 15:16:07

Conversation 08/20/2026

CEIE - Coord - During excavation/trenching, should you encounter any buried pipe or conduit that is anything other than uncoated metal or plastic material (e.g. cementitious or transite pipe, pipe insulation, pipe wrap, or coating applied to pipe), stop work, and contact the 30 CES/CEIEC Toxics Manager, , for assessment. Asbestos-containing material (ACM) shall not be disturbed. ACM pipe/insulated pipe can legally be abandoned in place. If removed, it must be accomplished by a Certified Asbestos Contractor.

Conversation 08/20/2026 CEIE - Coord - Avoid removal of oaks and chaparral shrubs; trimming is preferred, see attached "NR_Oak Tree Trimming Guide" for trimming guidelines. Provide planting plan strategy if chaparral is removed south of Hwy 1. Coordinate for weed seed inspection of heavy equipment used and planting plan approval; see attached "NR_VegetationWeedSeedCleaning_PlantingPlan".

Conversation 08/20/2026

CEIE - Coord - Any trenches or holes left open must be properly covered or have a ramp in place to prevent the entrapment of animals. See attached "NR_TrenchesAndPits" for guidance. If vegetation removal is necessary and work is conducted between 15 Feb and 15 Aug, nesting bird surveys are required and further coordination with Natural Resources. If any nesting birds are found, work will likely be delayed until the young fledged. See attached, "NR_Birds_VegTrimmingAndRemoval". POC:

STANDARD HAZARDOUS WASTE MANAGEMENT

COMMENTS/INSTRUCTIONS

Program Manager:

Directional boring may generate CCR Title 22 regulated drilling mud-slurry mix. The Contractor is required to submit drilling lubricant/additives/Bentonite cut sheets/SDS for all chemicals proposed for use.

Contact and/or email information to . Characterization of these chemicals will determine material drying and disposal options. Drilling- process wastes using any combination of the lubricants noted above must be captured/contained and shipped to an off-base facility permitted to accept this type of waste. Waste management and disposal is the responsibility of the individual contractor, however off-base shipment of these wastes must be coordinated/approved with this office (30 CES/CEI - ).

NOTE: If the drilling process uses only hydrant-water, the resulting mix of water/sand/soil can be dried within in a typically constructed concrete-type containment/washout, for later disposal off-base as Non- Hazardous waste. Deposition of dried waste drilling muds in on-base borrow pits is prohibited.

Oak Tree Trimming Guide

From Oak Tree Trimming Guide: Best Practices and Techniques https://mcculloughtreeservice.com/tree-trimming/oak-tree-trimming-guide/

Key Items

• Oak tree trimming should preferably be done in the winter months, from January to March.

• Clean and sanitize trimming tools before use to prevent the spread of diseases.

• Encourage the growth of a dominant leader branch for structural integrity.

• Cuts should be made at proper angles and outside the branch collar to avoid damage.

• No more than a third of the canopy should be removed at a time.

Cleaning and Sanitizing Your Tools

To minimize the risk of spreading diseases between oak trees, it’s essential to thoroughly clean and sanitize your trimming tools before you begin. This involves soaking all cutting equipment such as clippers and saw blades in a solution made up of nine parts water to one part bleach. After immersing the tools in the solution, allow them to air dry before usage. This sanitization practice is one of the best practices for trimming oak trees, helping to maintain the health of your oaks and preventing the transmission of harmful pathogens.

Selecting the Proper Equipment for Trimming

Equally as important as tool sanitization is selecting the correct trimming tools for the job. The key here is to use high-quality tools that are sharp enough to make precise cuts and suitable for the size of the branches you’re intending to trim.

Choosing the right equipment for your oak tree trimming task can prevent poor healing and unnecessary damage to the tree. The ideal kit should include pruning shears for smaller branches, lopping shears for branches that are slightly out of reach, and durable saws for larger branches.

Remember, a decent trimming job starts with the right tool selection.

Trimming Tool Ideal For

Pruning Shears Trimming smaller branches and twigs

Lopping Shears Trimming branches that are slightly out of reach

Saws Trimming larger branches

Covering Trenches and Power Line Pole Holes to Avoid Safety Issues and Animal Trappings

The typical powerline pole hole size is 8- 9 ft deep and 2 ft wide.

If plywood or wood is used make sure it is thick enough to not bend or warp with the weight of dirt and gravel bags on top.

Completely cover the edges with soil, plastic, etc. so that animals cannot climb in around the edges. Cover with gravel bag and a safety cone.

This contractor used a metal rectangular cap from a roofing project to cover this hole.

You can be creative with your cover as long as it’s safe and keeps animals and people out and away.

This contractor made use of the used wire spools. This worked great because the diameter of the spool was larger than the hole. They blocked the smaller holes with tape.

For odd sized holes or trenches you can also cover the hole with plastic or landscape fabric first and then cover the hole with wood or other type of solid cover. A long piece of 2x4 (or wider) wood can be put in shallow trenches (less than 2 feet deep) for animals to climb out.

Weed Seed Inspection Guidelines General guidance on cleaning prior to bringing equipment to Vandenberg SFB

Human activities often result in the unintentional introduction of non-native species into new areas.

Vehicles, earth-moving equipment, pumps, trailers, as well as clothing, shoes, and waders can become vectors that contribute to the spread of invasive species. Inspecting work equipment is essential in preventing the spread of invasive species and is much cheaper than controlling and managing invasive species after introduction. All vehicles and equipment being brought onto installation for a project must undergo this weed-seed inspection before being brought to the work site.

Vehicle Types (including but not limited to):

• Rubber-tired land vehicles & Drill Rigs

• Tracked land vehicles

• Construction and facility equipment

To prepare for these inspections, contractors should thoroughly clean and maintain equipment offsite to the required standards to prevent delays. Vegetation, soil, mud, and loose debris that can be removed or rubbed off by hand all have a chance of containing plant cuttings or seeds. This type of material must be entirely removed to prevent introduction of weeds to work sites. Wash stations are not provided on Vandenberg SFB.

Vehicle Areas that Warrant Particular Attention
