“How can we describe parcels and food freight shipments that can be moved in small containers?”

Freight transportation is typically talked about as if it exclusively belongs in large, heavy containers moved by rail, cargo ship, or truck. However, people can move smaller items like parcels and food by ferries and cargo bikes for “last-mile” delivery as Microfreight. Microfreight transportation is much less carbon and infrastructure-intensive. Cities can become more sustainable by switching more freight to microfreight. New York City is pioneering microfreight deployment.

“Why do people remove dams?”

Dams are constructed to harness hydroelectric power, suppress floods, irrigate agriculture, store drinking water, and much more. However, dams will degrade over time, and their drawbacks may outweigh their benefits. Consequently, people will undertake Dam Removal projects. Dam removal can restore riverine ecosystems to their natural state.

“How can we take a practical, secure approach to environmental safety in organizational operations?”

Environmental safety in organizational operations can vary drastically, ranging from simple catch-basin cleanup to nuclear remediation. While we can’t completely remove risk, we can heavily reduce to as low as reasonably achievable (ALARA, reduce it as much as you can achieve, such as going beyond basic care in heavy radiation settings) or as low as reasonably practicable (ALARP, reduce risk to as low as whatever fits guidelines/standards and is cost-benefit optimal). These ALARA/ALARP Principles are fundamental to creating a safe place for everyone.

“How can we make sure we’re safe during hazardous energy appliance maintenance?”

Maintaining an appliance with hazardous energy can be very dangerous. So what can we do to make sure we’re safe during this time? Well, what if we identify the hazardous energy sources, deenergize the energy sources,  use a lock to physically isolate the source of energy to ensure no accidental activation occurs, add a warning tag with our name and contact information, test the system to make sure energy was isolated, conduct maintenance work, and then get everyone out before removing locks and tags to renergize the system? Well, this is the idea behind Lockout/Tagout, a widely adopted hazardous energy maintenance protocol.

“How can we quantify the total amount needed to start a fund to generate enough interest to pay for a project?”

People can put down money to fund a project or scholarship for perpetuity. But how can we accomplish this? Well, what if we make an investment fund so large that the money made from interest will pay for annual costs? This is the principle behind Capitalized Costs, equal to the annual operating cost divided by the interest rate.

“How can we determine if waste will leach toxic chemicals when it rains?”

Surface waste management has to account for a lot of variables. One of them includes determining if the waste will leach toxic chemicals when it rains. SO what if we were to grind waste down like it was in a landfill, mix the waste with a weak acidic solution similar to acid rain, tumble the mixture for 18 hours, and chemically analyze the leachate output for contaminant limits? Well, these are the steps behind the TCLP — Toxicity Characteristic Leaching Procedure, an EPA RCRA procedure to determine the potential toxicity of waste leachate.

“What models the rules and regulations for U.S. engineering and surveying licensing boards?”

The NCEES Model Law defines the powers and duties of U.S engineering and surveying licensing boards. But it’s not complete by itself. The boards also require rules and regulations for member boards to implement the concepts defined in the law. These come in the form of The NCEES Model Rules. As an analogy, the NCEES Model Law is like defining a tool, while the NCEES Model Rules explain how to use the tool.

“What defines the powers and duties of U.S. engineering and surveying licensing boards?”

In the U.S., obtaining an engineering or surveying license is incredibly important to practice these professions in public service. Each state has its own licensing board that governs how engineers and surveyors are licensed to safeguard the health, safety, and welfare of the public. To help develop suitable and uniform licensing laws across all states, the National Council of Examiners for Engineering and Surveying (NCEES) has developed The NCEES Model Law to define licensing boards’ powers and duties.

“How does the U.S. federal government regulate solid and hazardous waste disposal?”

Solid and hazardous waste needs proper disposal and maintenance to protect public health. In 1976, the U.S launched the Resource Conservation and Recovery Act (RCRA) to administer “cradle to grave” requirements for hazardous waste landfill/disposal criteria for non-hazardous solid wastes.
