We have all heard the jokes like "How many engineers/lawyers/bureaucrats etc. does it take to change a light bulb." The basic premise is that the task is very simple, and rather than following the straightforward approach, these professionals overcomplicate the process. The purpose of a public notice is simply to inform the public that a permit has been applied for and is undergoing review, or that the final permit is about to be issued. There are public notices for many kinds of permits, water discharge permits, air permits and hazardous waste facility permits, but they all have the same purpose.

Pond algae and algae blooms are probably the most common recurring problem for ponds and lakes. Sometimes it seems that they appear out of nowhere, especially as the temperatures begin to rise. Eliminating and preventing an algae bloom can seem like an impossible task and can be very frustrating. Sometimes, they seem to keep reappearing no matter what action is taken. Treating and preventing algae blooms can be a daunting experience, however, there are several ways to reduce the frequency and severity of an algae bloom.

The American Burying Beetle (Nicrophorus americanus) is a federally endangered species characterized by its large size and distinctive black and orange coloring. This nocturnal beetle utilizes carrion for its life cycle, and therefore competes with vertebrates many times its size. Within the Mid-Continent region of the United States, the American Burying Beetle (ABB) is most commonly found in open fields, prairie-like grasslands, oak-pine and oak-hickory ecosystems, and along edge habitat. When an endangered species or its habitat may be impacted by a project, the US Fish and Wildlife Service (USFWS) often requires consultation under the Endangered Species Act (ESA). For projects where the ABB is concerned, presence/absence surveys are the first step of the consultation process. Apex has USFWS permitted surveyors on staff, who can perform surveys throughout the Mid-Continent region including; South Dakota, Nebraska, Kansas, Oklahoma, Texas, and Arkansas.

According to the U.S. Environmental Protection Agency (EPA), a "brownfield site" is a real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. After EPA established its Brownfields Program in the mid-1990s to promote the redevelopment of sites that were orphaned or abandoned due to actual or perceived environmental contamination, many states adopted voluntary cleanup programs (VCP) to oversee the assessment and remediation of brownfields and to encourage redevelopment of these sites by developers that had no involvement in the former site operations that may have resulted in contamination. A chief incentive for enrolling a site into a voluntary program is the issuance of a certificate of completion, something akin to a closure letter indicating no further action is required by the state, and something most lenders require before agreeing to loan money for redevelopment of contaminated sites.

Underground storage tanks (USTs) are used at numerous commercial and residential properties to store fuels and oils for refueling and maintaining vehicles and equipment, providing emergency back-up power, and for on-site heating systems. USTs may be used to store hazardous chemicals or other products, but petroleum storage tanks are by far the most common and are the focus of this article. Due to the nature of the stored substances, the volumes of liquid typically requiring storage, as well as the limited available space on most properties, it often becomes necessary to install storage tanks below grade. A UST is defined by Federal regulations as a tank that stores a regulated substance which has 10% or more of the system's volume—including the tank and associated piping—below the ground surface. Typical USTs vary in size from 550 gallons up to 50,000 gallons in capacity and can be found almost anywhere and everywhere including gas stations, automobile dealerships, commercial office buildings, industrial plants, colleges/universities, hospitals, and residences, just to name a few examples. Standard USTs are horizontal cylinders constructed of fiberglass, steel, and/or a composite material (e.g. fiberglass reinforced plastic (FRP), carbon fiber wrapped around a steel liner). USTs are often considered a necessary evil based on the environmental liabilities associated with their presence on a property.

On a recent project involving excavating a trench, Apex personnel suspected that the utility mark-out done by the state had mismarked a few lines. Acting on their hunch, Apex's crew hand dug around where the mark out was, as well as where they thought the line should be. The utility line was in the spot that was unmarked and a utility interruption was successfully avoided.
