Securing a Jurisdictional Determination

[vc_row][vc_column][vc_column_text]

 

A Jurisdictional Determination also known as a “JD” represents that US Army Corp of Engineers (Corps) determination of the presence and/or extent of “waters of the US” on a property. However, there are two types of JD’s. One represents the official findings of the Corps and the other is more or less an estimate. Both JD’s have their purposes. It is important to recognize the difference between the two types because one could get you into a lot of trouble.

Approved JD’s

An approved JD is an official Corps determination that jurisdictional “waters of the United States,” or “navigable waters of the United States,” or both, are either present or absent on a particular site. An approved JD precisely identifies the limits of those waters on the project site determined to be jurisdictional under the Clean Water Act and/or the Rivers and Harbors Act.

An approved JD:

  1. Constitutes the Corps’ official , written representation that the JD’s findings are correct;
  2. Can be relied upon by a landowner, permit applicant, or other “affected party” (as defined at 33 C.F.R. 331.2) who receives an approved JD for five years (subject to certain limited exceptions explained in RGL 05-02);
  3. Can be used and relied on by the recipient of the approved JD (absent extraordinary circumstances, such as an approved JD based on incorrect data provided by a landowner or consultant) if a CWA citizen’s lawsuit is brought in the Federal Courts against the landowner or other “affected party,” challenging the legitimacy of that JD or its determinations; and
  4. Can be immediately appealed through the Corps’ administrative appeal process set out at 33 CFR Part 33

If wetlands or other water bodies are present on a site, an approved JD for that site will identify and delineate those water bodies and wetlands that are subject to Clean Water Act jurisdiction, and serve as an initial step in the permitting process.

Preliminary JD’s

Preliminary JDs are non-binding, “… written indications that there may be waters of the United States, including wetlands, on a parcel or indications of the approximate location(s) of waters of the United States or wetlands on a parcel. Preliminary JDs are advisory in nature and may not be appealed.”

The main purpose of a Preliminary JD is speed a project along. There are several scenarios where this type of JD would accomplish this.

  1. An applicant, or other “affected party” may elect to use a preliminary JD to voluntarily waive or set aside questions regarding CWA jurisdiction over a particular site, usually in the interest of allowing the landowner or other “affected party” to move ahead expeditiously to obtain a Corps permit authorization where the party determines that is in his or her best interest to do so.
  2. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S.
  3. Preliminary JDs are also commonly used in enforcement situations because access to a site may be impracticable or unauthorized, or for other reasons an approved JD cannot be completed in a timely manner. In such circumstances, a preliminary JD may serve as the basis for Corps compliance orders (e.g., cease and desist letters, initial corrective measures). The Corps should support an enforcement action with an approved JD unless it is impracticable to do so under the circumstances, such as where access to the site is prohibited.

It is the Corps’ goal to process both preliminary JDs and approved JDs within 60 days as detailed in paragraph 5 below, so the applicant or other affected party’s choice of whether to use a preliminary JD or approved JD should not affect this goal.

In 2008 the Corps published a Regulatory Guidance Letter (RGL) No.08-02 dated 26 June 2008. This RGL should be consulted prior to applying for either type of JD. It is also important to note that it is also required that a JD form be completed and submitted with the JD application. This form sets forth the data required to make the JD determination. Most Corps districts have guidance on how to fill out the form and “short cuts” that are district specific. The above RGL and attached JD form sometimes referred to as the “Rapanos Form” can be found here ==> RGL 08-02.[/vc_column_text][/vc_column][/vc_row]

Wetland Soil Auger Buyers Guide

Wetland Soil Augers

augers

One of the most frequently asked questions by our wetland delineation students is, “what type of soil auger should I buy?”

A quick browse though any of the forestry supply companies catalogs and you are quickly overwhelmed. Who would have thought that there we so many different types of soil augers. Some of them are quite expensive. Many are modular and you end up buying part of an auger and have to order more parts. You do not want to drop a grand on an auger only to find out it is not what you needed or expected.

To help you get a handle on this I have put together a brief pros and cons of the most common soil augers used for wetland delineation. This list is based upon my personal field experience with these augers. Each has its place so be prepared to buy a few. I do have a favorite all around auger which I will also cover, but I own a bunch.

Tube Sampler

tubesampler

This is a favorite for the beginning wetland delineator. One of its biggest assets is it is the cheapest. However it has limitations. The basic construction is a simple tube that is cut open at the bottom. There is usually about a 16 inch half pipe slice that is used to examine the soil profile in-situ. The very end is a ring that everyone gets their fingers stuck in. A good one is about 24 inches in length with an opening extending about 16-18 inches. There is a short t-handle on the top. Sometimes this is detachable with a screw fitting. Others have the handle welded on. The former is a bit more expensive.

One of the biggest advantages to this type of auger is the small footprint it makes. In glacial regions it is sometimes the only auger that can get in between the rocks. It is also very handy for quick assessments.

The biggest disadvantage is the relatively small amount of soil sample this auger extracts. Oftentimes, it just is not enough sample to make a wetland determination. Small rocks are also a problem as they will plug up the tube end. The issue of cleaning it the sampler end out is also a challenge. Don’t stick your finger in the end. It is sharp and just the right size to get your finger stuck. Use a stick to clean it out.

Screw Sampler

This auger looks like a giant cork screw. The screw is about a foot long and is about 2-3 feet in total length. The screw is usually attached by extension bars that can be added to achieve a comfortable length. It has a slightly larger footprint than the tube sampler and is similarly useful in glaciated regions.

The biggest challenge with using this auger is the ability to measure the thickness of a hydric soil feature. The screw blades are about .5 inches thick. This results in a stretching of the soil sample. It is hard to estimate how thick a feature may be using this auger. It also provides a very small about of soil sample.

Bucket Auger

This is probably the most common type of auger used by soil scientists. Not necessary wetland delineators however. The basic design looks like a coffee can with one end open and the other end has two blades welded onto it. An extension bar connects in between the bucket and a t-handle on the top. All of these items can be customized to fit the user’s needs.

If you are just starting out delineating, you will probably be handed one of these bucket augers. There always seems to be one hiding in a closet in the office. Someone bought it, used it once and there it sits.

I do not have a lot of pros to offer with this type of auger. The biggest problem is that it grinds up the soil profile making it very hard to distinguish the hydric features if the soil. It also requires that once you auger down and grab a sample you then have to tip the bucket upside down and bang out the sample. This also obscures the features.

Soil scientists like these augers because they are trying to obtain a discrete sample at a specific depth. This is usually why the extension bars are so long. I have seen some augers used in the field that were over 6 feet long. This is very hard to use if you are 5’6” tall.

Dutch Auger (My Favorite)

This auger was made for wetland delineations. It is a double blade at the end of an extension bar and t-handle. It cuts a very nice sample without disturbing the profile integrity. You can usually auger down several feet fairly easily and lay out the samples in more or less the same way they would be found in the pit. You also get a decent amount of sample to play with.

There are a number of brands and styles of this type of auger. The biggest difference between the individual styles is a represented by the size and pitch of the blades. The original use of the Dutch auger was for muddy soils. However, there have been many modifications to the design and there is such a thing as a combination auger that works well in loamy soils as well as mud.

Sharp-Shooter

shovel

 

This is also known as a tree planting spade. It is simple a shovel that is 4 inches wide and 16 inches long. It digs a small hole and cuts a nice sample. In a pinch this shovel will work in almost any circumstance.

The biggest advantage to this sampler is the cost. You can pick one if these up in your local home improvement center for about $25. Most of the other augers mentioned are well north of $200.

The biggest down side to this device is the work associated with it. Digging a hole is a lot of work. You get a nice amount of sample and you can even cut a nice sidewall to see the profile. However, this took a lot of work.

Quick Connect or Not

One last note on the issue of quick connects. To be frank, I have yet to see one of these work once they were put into field use. The fittings get gummed up with dirt and the quick connects jamb. I would suggest going with an all welded design. You are not going to take these apart anyway so why spend the extra money. If you need to travel by airplane, TSA is not going to let you carry these on so there is no need to break them down. Just check them or better yet, buy a shovel for $25 when you get to the job site.
