Sorry, any area with petroleum products was ingrained into my head - head why I indicated "all". It's floor drains that have oil, grease, or flammable wastes that have the potential to discharge through the drains.

For New York State, it's in the Plumbing Code. Requires all floor drains to discharge to an oil/water separator prior to discharging to sanitary sewer (could be as simple as a retrofited septic tank). Your DEC or even EPA probably regulates the discharge of floor drains to storm systems...

How should I run a dual hydrologic soil group (A/D) in TR-55? It appears the soil group is defined A/D due to the shallow water depth, however, still has drainage characteristics of an A soil. Should I run it as all A soil or 50% A / 50% D?

Hi All - I'm working on a project located adjacent to a CP Railway - anywhere from 20-50 ft from the tracks. It's a main trunk sewer main - 18" diameter. We originally designed the pipeline to be PVC, however, during the review process with CP Rail and in accordance with AREMA standards, they...

Thanks for the replies. I'll be talking to my supervisor to discuss this issue. This was never really an issue previously because I never had the workload to work past 40 hrs per week. I've worked for this company for 2 years. In the past 6-9 months my responsibilities have grown (without...

How's overtime typically work with the firms you work with? I currently am a civil PE that works for an A/E firm and a majority of us are salary. We're overly busy with too much work right now. We are not paid for overtime, so I generally do not work overtime unless it's necessary (i.e...

How old is it? General rule of thumb for our area is 20-25 years depending on maintenance and soil conditions. You could try putting dye into the sink and running water, lots of water, to see if the system could accept it. Just a thought. If it fails, the dye might come out of the ground or...

I previously worked for a Design-Build company and have since moved on to a traditional engineering company. The design-build company had an in-house civil engineering division and an in-house excavation (construction) division. Since I've moved on, I've always wondered if this situation would...

I have a project with a maintenance garage floor drains discharging directly to the sanitary sewer. According to the Town sewer ordinance and plumbing code, an oil/water separator is required prior to discharging to the sewer. Did some research, called reps, etc. Found a wide variety of...

If your closest hit was a couple miles away, I bet you'll be fine. Fill out the SHPO form and send it to them. My guess is you'll get the "no impact" letter. Quick project description, location map, and photos....should take you 0.5 hrs to complete. SHPO will then determine if Phase IA or IB...

Did you look at their new GIS based website to see if you are in an archaeological sensitive area? I've been lucky enough to only receive their "no impact" letters. Had one that was located in a sensitive area but in my description, we indicated that it had been completely disturbed (upper...

Google "Proposed Accessibility Guidelines for Pedestrian Facilities in the public Right-of-Way" - July 26, 2011.....Around pg 94, it discusses ADA for parallel parking. I had to use this standard for a NYSDOT highway work permit.

Thanks for the input. I ended up modeling this in AutoDesk's Storm and Sanitary Analysis. Fairly straight forward once you figure out the input parameters.

You should be fine. I took the 2013 April exam. Started studying Feb 1st and didn't have a problem. I took the week before the exam off, as well.

I'm looking for a good resource or design manual for the design of infiltration chambers. Particularly separation from groundwater and bedrock. I've contacted a couple manufacturers, however, each of their 'simple' designs do not take into account infiltration rates, groundwater levels...

Have you tried bringing orthos into AutoCAD?

Your 10' of head seems low for 20 gpm. For these systems, you'll need effluent pump only. Check out the NYSDOH septic design handbook, they have good examples on how to design these systems.

Skip the review class. I just took mine in April and used online resources. Check out these sites: www.learncivilengineering.com engineeringregistration.tamu.edu/tapedreviews engineerboards.com I started off with the Texas A&M videos. They are old but most of the info is still good. I...

I'm in the process of designing/researching the removal of TDS from a stormwater pond at a mining facility. The facility that I'm working on is pumping mine water to a stormwater pond. TSS settles in the forebay, however, TDS (currently a stained, greenish tint in the water) is present in the...

Phase I Environmental Site Assessment is usually required by banks during commercial property transactions. Basically a building inspection but aimed towards environmental issues (i.e., spills, petroleum, asbestos, etc). There's deed research and interviews performed, as well. This is usually...
