Rapid Marine Environmental Impact Assessment (RMEIA) studies off Pydibhimavaram Foreword M/s Aurobindo Pharma Limited was commenced operations in 1988-89 with a single unit manufacturing Semi-Synthetic Penicillin (SSP) at Pondicherry. It became a public company in 1992 and listed its shares in the Indian stock exchange in 1995. In addition to being the market leader in Semi-Synthetic Penicillins, it has a presence in key therapeutic segments such as neurosciences, cardiovascular, anti-retrovirals, anti-diabetics, gastroenterology and cephalosporins, among others. Aurobindo Pharma Limited (APL) has set up a bulk drug manufacturing unit at Pydibhimavaram village, Ranasthalam Mandal, Srikakulam District of Andhra Pradesh during 2001 in order to meet its market and export demand. The Industry is discharging the treated effluent into the sea through a pipeline from the coast as a safe disposal for quick dispersion. The Industry has proposed expansion of the existing facility to meet the global demand. It is mandatory for a costal base industry to monitor the marine environment and bioassay tests for the treated effluent to study the effects. In this process the M/s Aurobindo Pharma Limited (APL) has approached CSIR-National Institute of Oceanography, Regional Centre, Visakhapatnam for these studies to know the cumulative effects, if any, on the ecology, water quality and sediment quality due to the discharge of treated effluent into the marine environment. After examining the proposal, CSIR-NIO agreed to carry out the field study to generate one time <ul style="display: flex;"><li style="flex:1">site specific data on the oceanographic parameters including dispersion. </li><li style="flex:1">CSIR-NIO has </li></ul>conducted a field campaign for in-situ observations and sample collection for chemical, biological and microbiological parameters and sediment characteristics at and around the marine outfall point (MOP) of the APL, off Phydibhimavaram, during 26 May - 6 June 2018.

M/s APL, Unit XI is currently producing 45 products out of 64 products at a time excluding consent for captive power generation is included in Group C along with the products consented to be manufactured. In order to meet the global demand the industry has once again proposed to go for expansion by introducing new products developed by R&D. During the expansion, the industry has proposed to increase its manufacturing capacity from 583.31 TPM to 1518.3 TPM and captive power plant to 8.85 MW within the existing site area of 165 acres. The Industry is discharging the treated effluent into the sea through a pipeline from coast as a safe disposal for quick dispersion. Monitoring of the marine environment and bioassay tests for the treated effluent are mandatory for any coastal based industry discharging its effluent into the sea. Council of Scientific and Industrial Research – National Institute of Oceanography (CSIR-NIO) has conducted a field campaign for in-situ observations and sample collection for chemical, biological and microbiological parameters and sediment characteristics at and around the marine outfall point (MOP) of the APL, off Phydibhimavaram, during 26 May - 6 June 2018 in order to study the cumulative effects, if any, on the ecology, water quality and sediment quality due to the discharge of treated effluent into the marine environment. Physico-chemical parameters such as temperature, salinity, pH, dissolved oxygen (DO), biological oxygen demand (BOD), dissolved inorganic nutrients (phosphate, silicate, nitrite, nitrate and ammonium), chlorophyll-a, phenols and total suspended matter, and the biological characteristics such as abundance and composition of phytoplankton, zooplankton and benthic plankton in the study region are consistent with the ambient seawater conditions. Based on the 9Rapid Marine Environmental Impact Assessment (RMEIA) studies off Pydibhimavaram baseline monitoring studies available for site and modelling studies (near-field and far-field), it is recommended that the effluents can be released with two options. The effluent to the tune of 3.5 MLD can be released at present location 18°04’23.00’’N 83°40’51.00’’ E as an option I or the combined effluent to the tune of 5.0 MLD can be released at another location, 18°04’51.21’’ N 83°41’04.00’’ E, with a well defined diffuser specifications (chapter 12) as an option II. During the lay down of pipeline an area of about 0.53 ha is likely to be disturbed assuming a corridor width of 5 m and total length of 1060 m. Based on the results the probable loss of standing stock of macrobenthos (biomass and population) and affected faunal groups during the construction phase would be relatively low. Considering the benthic potential of the study area, such losses are unlikely to be reflected on the overall biopotential of the coastal marine system off Pydibhimavaram coast. Moreover, this loss would be temporary and the benthos would recolonise in due course after the laying is completed and construction activities are terminated. Probable impact of release of the treated effluent at the designated site through a suitably designed diffuser on water quality is predicted based on probable dilution that the effluent would attain and assuming conservative behaviour of constituents in the receiving water. Concentrations of pollutants such as BOD in the receiving medium would be lower than predicted on the basis of conservative mixing because of decay and/or physical transformations of several pollutants on entering water that leads to reduction in their concentration. Based on model results, salinity may decrease by about 0.1 ppt in a limited area around the diffuser subsequent to the effluent release. An incremental decrease of this order, that too in a small area, is unlikely to negatively influence the biota even in the vicinity of the diffuser. The model also predicts an increase of about 1.8 mg/l in option I and increase of 1.5 mg /l in option II for BOD. The field of influence of increase in salinity and BOD would vary between 20 m and 70 m length along the adverted plume. The impact would not be evident beyond 70 m (max) distance from the outfall location.
