Abstract: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Scope: This guide documents methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Purpose: Intrusion by animals into electric power supply substations has been a problem experienced by most of the electric utility industry. The costs associated with outages caused by animals continue to escalate. Although animal problems differ in nature geographically, the damage to equipment, interruption of or loss of service to customers, and safety problems encountered by operating personnel result in similar general concerns. This guide identifies various animals, the problems they cause, and mitigation methods. Further, it recommends criteria for applying mitigation methods, documents survey-reported effectiveness of various methods, and recommends factors for evaluating effectiveness of methods once they are applied.
The United States Food and Drug Administration and the National Coffee Association recommended standard temperature for safe hot coffee is around 160°F to 165°F (71°C to 74°C). This temperature range is considered hot enough to be enjoyable while minimizing the risk of scalding or burning.
These agencies do not have specific regulations or guidelines solely dedicated to cold brew coffee. However, there are general principles and best practices for handling and storing perishable food products that can be applied to cold brew coffee to ensure safety.*
Cold brew coffee typically requires more time to prepare than traditional hot brew coffee. While hot brew coffee can be made in just a few minutes, cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, usually between 12 to 24 hours.
The longer steeping time allows the coffee to extract more slowly and results in a smoother, less acidic coffee concentrate. After steeping, the coffee grounds are usually filtered out and the resulting concentrate can be diluted with water, milk, or other liquids and served over ice.
While cold brew coffee does require more time to prepare, many coffee drinkers prefer its smoother, less bitter taste and lower acidity compared to hot brewed coffee. Additionally, the longer shelf life of cold brew coffee concentrate makes it a popular choice for those who like to prepare coffee in advance and have it ready to drink throughout the day.
We cover the technical standards applicable to small to medium sized coffee preparation installations in a cross-cutting way during our Kitchens 200 colloquium.
* These recommendations are based on general food safety practices:
Water quality: Start with clean, potable water to brew your cold brew coffee. Make sure the water source is safe and free from contaminants.
Brewing process: Follow good manufacturing practices and ensure that your brewing equipment and utensils are clean and sanitized. Cold brew coffee is typically brewed using room temperature or cold water over an extended period. Ensure that the brewing container is properly sealed and protected from any potential sources of contamination.
Filtration: After the brewing process, filter the cold brew coffee to remove any sediment or particles. This can be done using a fine-mesh sieve or a dedicated filtration system.
Storage: Store the cold brew coffee in a clean, airtight container in the refrigerator. This helps to inhibit the growth of bacteria and maintain the quality of the coffee. Cold brew coffee can typically be stored for a few days to a couple of weeks, depending on the specific recipe and preparation method.
Temperature control: Keep the cold brew coffee refrigerated at a temperature below 41°F (5°C) to prevent the growth of harmful bacteria.
Serve safely: When serving cold brew coffee, use clean and sanitized utensils, containers, and dispensing equipment to avoid cross-contamination. If you add any additional ingredients like milk or sweeteners, ensure that they are stored properly and do not exceed their recommended storage times.

In these clips — selected from Canadian Parliamentary debate in 2013 — we observe three points of view about Incorporation by reference(IBR); a legislative drafting technique that is the act of including a second document within a main document by referencing the second document.
This technique makes an entire second (or referenced) document a part of the main document. The consensus documents in which we advocate #TotalCostofOwnership concepts are incorporated by reference into legislation dealing with safety and sustainability at all levels of government. This practice — which many consider a public-private partnership — is a more effective way of driving best practices for technology, and the management of technology, into regulated industries.
Parent legislation — such as the Higher Education Act of 1965, the Clean Air Act and the Energy Policy Act – almost always require intermediary bureaucracies to administer the specifics required to accomplish the broad goals of the legislation. With the gathering pace of governments everywhere expanding their influence over larger parts of the technologies at the foundation of national economies; business and technology standards are needed to secure that influence. These standards require competency in the application of political, technical and financial concepts; competencies that can only be afforded by incumbent interests who build the cost of their advocacy into the price of the product or service they sell to our industry. Arguably, the expansion of government is a reflection of the success of incumbents in business and technical standards; particularly in the compliance and conformity industries.
About two years ago, the US debate on incorporation by reference has been taken to a new level with the recent statement released by the American Bar Association (ABA):
The incorporation by reference policy dilemma has profound implications for how we safely and economically design, operate and maintain our “cities-within-cities” in a sustainable manner but, admittedly, the results are only visible in hindsight over a time horizon that often exceed the tenure of a typical college or university president.
A recent development — supporting the claims of ANSI and its accredited standards developers — is noteworthy:
The National Institute for Standards and Technology (NIST) manages a website — Standards.GOV — that is a single access point for consensus standards incorporated by reference into the Code of Federal Regulations: Standards Incorporated by Reference Database. Note that this database does not include specific reference to safety and sustainability codes which are developed by standards setting organizations (such as NFPA, ICC, IEEE, ASHRAE and others) and usually incorporated by reference into individual state public safety and technology legislation.

Alumni Memorial Hall was built as a war memorial and multi-purpose alumni building — not originally as an art museum; though it became — and still is — a gathering point for alumni who donated their collections to the University. Its inspiration originated in 1864 shortly after the Civil War, to honor University of Michigan students, faculty, and alumni who died in that conflict and all conflicts thereafter.
Today we review a draft of an article that covers, in our view, an obvious oversight in the 2026 National Electrical Code. It is an expansion of a proposal already submitted to the National Electrical Code Technical Correlating Committee and will support challenges to its adoption into the 2029 NEC revision.

Restore the NESC to the Front End of the NEC
Michael A. Anthony | Glenn T. Keates
Abstract. It may seem like a small thing — to restore the cross-reference to the IEEE National Electrical Safety Code (NESC) at the front end of the NFPA National Electrical Code (NEC) where it used to be — but it is not. This paper explains why restoration of the NEC’s peer document is necessary in the 2029 Edition of the NEC, now under development.
The reasons are both technical and cultural, touching on a minefield of sensitivities about safety, sustainability, and economic development associated with the data center (artificial intelligence) zeitgeist.
Customer owned interactive sources are not new. Customer-owned load-side electric services at transmission voltages for private developers and university-adjacent hyperscale installations present consideration are new.[x]
The NESC, in contrast, maintains a clear “handshake” reference to the NEC in its Scope statement (Section 011). This paper argues for the restoration of a prominent NESC cross-reference in NEC Article 90.2(A)(2) for the 2029 edition. The proposal (Public Input No. 3687-NFPA 70-2026) has already been submitted to NFPA Technical Committee CMP-1.
