Not necessarily. If you submit for a NDDB Review Request after receiving a Site Assessment report, the response will be based on project details provided in your application. If the reviewing biologist determines that additional information is needed, details will be indicated in a follow-up letter. Read your letter carefully (*see sample below). In some cases, a habitat evaluation may be sufficient, or you may need a qualified biologist to conduct specific biological field surveys. Ideally, field surveys are recommended in order to evaluate potential habitat and species presence, and use of the site. Highly developed sites with little suitable habitat or projects with minimal or temporary impacts may not need surveys. You may be able to minimize disturbance or pollution; develop avoidance, preservation, or mitigation measures; or design habitat buffers or improvements based on your knowledge of the site conditions alone.
Sample Site Assessment Letter (This is an example only. Language provided may differ slightly depending on the individual review.)
According to our records, there are known extant (existing) populations of state-listed species that occur within or close to the boundaries of this property. Attached is a list of species known from this area. Please be advised that this is a preliminary review and not a final determination. A more detailed review will be necessary to move forward with any environmental permit applications submitted to DEEP for the proposed project. This preliminary assessment letter cannot be used or submitted with permit applications at DEEP. This letter is valid for one year.
To prevent impacts to state-listed species, field surveys of the site should be performed by a qualified biologist with the appropriate scientific collecting permits at a time when these target species are identifiable. A report summarizing the results of such surveys should include:
Responding to a Survey Requirement
The site surveys report should be sent to the reviewing biologist and the CT DEEP NDDB Program (deep.nddbrequest@ct.gov) for further review.
Incomplete reports may not be accepted.
NDDB information includes all information regarding critical biological resources available to us at the time of the request. This information is data collected over the years by the DEEP’s Natural History Survey, other DEEP scientists, landowners, private conservation groups, and the scientific community. This information is not necessarily the result of comprehensive or site-specific field investigations. Consultations with the NDDB should not be substitutes for onsite surveys necessary for a thorough environmental impact assessment. The result of this review does not eliminate the possibility that listed species may be encountered on site and that additional action may be necessary to remain in compliance with certain state permits.
It is important to keep track of your filing numbers. In My Home/Filings, find the filing in your online portal under Finalized Filings. Under Info, select the fourth icon, the circle arrows, and follow the prompts to renew with no modifications or to copy forward if there are modifications needed.
If you cannot find your filing, or if your original determination was not entered in the portal, you can always submit a new request. For a renewal of a determination that was not entered in the portal, you can make note in the project description that this is a renewal of a previous determination, and include the previous determination number, and if applicable the reason for the renewal.
Each application should be for one project type at a single site; however, multiple areas within a reasonable distance can be added. For example, you can draw your construction footprint and stormwater discharge location as two polygons in the same application. Polygons that are too far apart may make it difficult to interpret your results. You can either upload a zipped shapefile, or draw multiple polygons. For each polygon, you will be required to fill out all the attributes in order to continue. If you draw multiple polygons, a pop-up alert will appear stating that one or more of your polygons is missing one or more required attributes. Select "okay" and you will be prompted to fill in those attributes.
Upload instructions: Prior to uploading, create a polygon shapefile of your project area, including the area of work and any access, staging, or discharge areas. Zip all components of a single polygon shapefile and use the upload tool to navigate to your saved zipped file. After uploading, you will need to click on each individual polygon in the map and add labels before you can continue.
