S.No Query Reply 1. Form-1 for project attracting CRZ Notification, 2011 as per Annexure-IV in Form-1 for project attracting CRZ Notification, the said notification is not available, 2011 as per Annexure-IV is enclosed as which is one of the statutory documents Annexure I as per the CRZ regulations. 2. It was also observed that the proposed As a wetland ecosystem the Pulicat lake area project may affect the migratory bird, is important for the breeding and roosting birds since Pulicat Bird Sanctuary is located and several other fauna and flora. within 10 km of the project site. Therefore, report of the study already It is important for the development authorities conducted by Salim Ali Institute of to note that any construction activity must Ornithology may be submitted. commence and complete before the bird migratory season. M/s. Salim Ali Institute of Ornithology (SACON) has conducted study for assessing the Impact of dredging and opening of the sea mouth into the Pulicat lake at Rayadoruvu village of Vakadu Mandal on the habitat of Pulicat Bird Sanctuary at Andhra Pradesh and Proposed High Level Bridge across Pulicat Lake at Tamil Nadu with Special Focus on Birds, which is very near to the location of site for Permanent Stability of Bar Mouth. So the study by SACON towards migratory bird for the S.No Query Reply Bridge work is enclosed herewith for reference. Necessary mitigation measures must be undertaken to reduce indirect impact on the Pulicat Bar mouth at various phases of development to the surrounding wetland habitat, woody vegetative cover and the overall ecology of the site. The indirect impact may be due to the release of contaminated, polluted or untreated water, debris, or other materials from the construction phase. Abstract of the Study Report conducted by Salim Ali Institute of Ornithology enclosed as Annexure II 3. Data on fishery as to how much As per the marine fish production data from the reduction in fishery has been observed in Fishing Department, fish production capacity past years may be submitted was 12025 during the period 2004-2005, which was reduced to 9498 in 2018-2019. Detailed fishery data is enclosed as Annexure III. Ramanibai Ravichandran, Department of Zoology University of Madras, study which was carried out from September 2013 to August 2015 clearly indicates that fish samples collected were of 83 different fish species, 14 orders and 50 families. In which the major dominant order of the collections were observed as Perciformes which is nearly 44 species out of 83. However, according to the recent survey, the above mentioned fish species in the pulicat lake region are currently moving towards an extinction and they are recently specified as an endangered species in the vicinity. Therefore a serious conservation action/step is to be taken in view of preventing the loss of biodiversity. By opening of Bar mouth the species growth will be enhanced by the flow of Sea water in to the Pulicat Lake. 4. Since the proposal is related to making a Secondary data collected from the previous permanent opening at the bar mouth study highlights, the important trends in annual data on salinity of the lake is also and seasonal differences in mean salinities important, therefore available data on variations (in the range of 21 −36 ppt) as salinity of the lake over the past 10-20 observed in the period 1996–2015.The Study years shall be submitted report by M/s.
