2.  Site boundary was marked and verified from the Engineer-in-charge before taking up
                       the field work.
                   3.  All existing features like, trees, all types of structures/ buildings, concrete platforms,
                       roads, garage, workshops, weigh bridges, high-mast lighting units, power/ telephone/
                       OFC  lines,  pylons,  drainage  course  (both  lined  &  unlined),  green  space,
                       encroachments, hutments, etc., were located accurately.
                   4.  Top and bottom edges of MSW heaps were located accurately.
                   5.  Based  on  the  site  conditions,  survey  was  carried  out  beyond  site  boundary  up  to
                       about 30-50m to locate habitation, religious centers, roads, wells, drain, stream/ river/
                       creek or any other prominent features as per the directions of the Engineer-in charge.
                   6.  Block levels were taken at 5m interval within the site in a systematic manner along
                       the grid lines. Wherever the topography changes sharply, extra levels were taken to
                       get the realistic ground profile. Reduced Levels were calculated with respect to the
                       GTS Bench Mark.
                   7.  Contours were generated at 0.5 m interval.

                       WEIGHMENT STUDY:
                       For quantity of daily waste coming to the site, all the vehicles involved in collection
                       and transportation of solid waste should be weighed at the nearest weighbridge. The
                       vehicles made 2 -3 trips per day. Every trip of the vehicle should be measured at the
                       weigh bridge to get the accurate data. The net weight of waste should be calculated
                       by  adding  all  the  data.  Similar,  activity  should  be  conducted for  three  consecutive
                       days. The average of waste quantity for all the three days will give the quantity of
                       waste dumped at site per day.
                       At present, the weighment data has not been received from the RNN, considering the
                       population of 132559 and floating population of 12344 as well as assuming the per
                       capita  generation  of  400  gm/capita/day,  the  total  per  day  waste  generation  of
                       Rishikesh city is 57.96 TPD. The same will be verified after receiving the weighment
                       data from RNN.

               3.5 LEGACY WASTE QUALITATIVE ASSESSMNET

                      The qualitative assessment for legacy waste is yet to be carried out for Rishikesh
                      city. The legacy waste sampling methodology and parameters to be analyzed was
                      adopted as per CPHEEO Manual.
                      The qualitative assessment of the dumped legacy  waste at the dumping ground,
                      especially  its  physical  and  chemical  properties  is  essential  for  determining  the
                      future  technological  options  for  its  treatment  and  disposal.  The  finding  from  this
                      study is feed into the process and facilitates taking future decisions, especially in
                      terms of selection of the technology.

                      Details of the characterization study are attached in Annexure IV.
                 3.5.1 SAMPLING METHODOLOGY

                   1.  Identification of different locations considering the surface gradient of the dumpsite
                       from up-gradient to down-gradient. 2 samples in cross-gradient of the site need to be
                       taken.
