Environmental Statements
Environmental Statements
Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.
Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.
The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:
- environmental baseline conditions
- potential environmental impacts
- mitigating measures
- residual environmental impacts
There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.
Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.

Becoming Energy Efficient – Save the Planet
Becoming Energy Efficient – Save the Planet
Save the planet! As Earth Day approaches April 22, what are you doing to get ready? Earth day is an event that started to bring attention to our environment. How we handle our garbage reflects our environment. Here are three tips to help save our environment.
- First, recycle. Recycling is taking some of our garbage and reusing it, directly or indirectly. To recycle a water bottle, you may reuse it again and again. But for gallon milk jugs or 2 liter soft drink bottles, you may opt to collect them and bring them to a recycling center. The recycling center will forward them on to a company that will melt them down and reprocess them.
- Second, shop efficiently. Try using what your Grandma used when she cleaned her house. Try using vinegar and baking soda. There are lots of sites that recommend natural cleaning products instead of chemicals. Also, buy those products in bulk. It reduces packaging which ends up in our garbage dumps and it may be cheaper, the more you buy, the cheaper it is.
- Third, conservation. Since I already have compact fluorescent light(CFL) bulbs installed, turning off the lights when I leave is the next best thing. My Mom always told me to turn off lights when I leave a room. She was right. Using more electricity only raises your electric bill. It will also increase your carbon footprint.
Education is a goal of Earth Day. Educating everyone from adults to children can get involved. Challenge your kids to come up with projects to bring attention to our environment. When we teach our next generation, we are saving our planet. But first, we must start ourselves. Be a steward of what God gave you. Become energy efficient by recycling and conservation. Our planet is worth it.
And now I would like to invite you to join me in learning energy saving tips you can do yourself to decrease your electric bill at http://energyconsciousconsultant.com Energy conservation should be out goal.
Is Making Biodiesel at Home Safe? – Home Bio Diesel Production
Is Making Biodiesel at Home Safe? – Home Bio Diesel Production
The flammability point of biodiesel.
I’ve mentioned that it’s biodegradable that it’s safe to use blah, blah, blah, all these different things, but I want to show you how safe this is. This biodiesel, I’ve made from canola oil, so I’m going to pour a little bit in here, and now it’s time to play with fire. We’re going to come down here. Light up our torch, notice I have my fire extinguisher people.
We now have a nice blow torch going. Notice I’ve got some nice biodiesel on the ground here. I want to show you that biodiesel is very, very safe to have around. I can’t light it on fire. This torch is a really hot torch. I’m actually using map gas. Map gas actually has a higher flame temperature. So I’m just trying to light this sucker on fire, and you know what, she’s not going. That’s because biodiesel isn’t actually that flammable. It has a much higher flash point than normal diesel, and I’ve just proven it.
And that’s one of the reasons people like biodiesel is because it’s so safe to use. In fact, if this stuff spills on the ground the MSDS and things that it calls for is get a garden hose and wash it off. It’s not going to light up. It’s as safe to have around as vegetable oil. No I have to cavy up that this biodiesel has been cleaned. We have got all the methanol out of it, and we’ll talk a little bit about that later, but I just want to show you that it’s very clean and it just doesn’t burn. That’s that little fun experiment. We want to show you that biodiesel will burn though. When it’s under pressure it does burn quite well. For this experiment I’m just going to start a fire, and I’m going to spray it into it. As you can see it will burn, so when it’s in your diesel and it becomes injected, it will burn beautifully. That’s biodiesel burning.
The DR Performance Diesel Products & Edge Diesel Products are both fully compatible with biodiesel- Nathan Young
